The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM)^[1]^[2]^[3]^[4]^[5]^[6]^[7] is a dynamic rainfall-runoff-subsurface runoff simulation model used for single-event to long-term (continuous) simulation of the surface/subsurface hydrology quantity and quality from primarily urban/suburban areas. The hydrology component of SWMM operates on a collection of subcatchment areas divided into impervious and pervious areas with and without depression storage to predict runoff and pollutant loads from precipitation, evaporation and infiltration losses from each of the subcatchment. In addition Low Impact Development (LID) and Best Management Practice (BMP) areas on the subcatchment can be modeled to reduce the impervious and pervious runoff. The routing or hydraulics section of SWMM transports this water and possible associated water quality constituents through a system of closed pipes, open channels, storage/treatment devices, ponds, storages, pumps, orifices, weirs, outlets, outfalls and other regulators. SWMM tracks the quantity and quality of the flow generated within each subcatchment, and the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period composed of multiple fixed or variable time steps. The water quality constituents such as water quality constituents can be simulated from buildup on the subcatchments through washoff to a hydraulic network with optional first order decay and linked pollutant removal, Best Management Practice (BMP) and Low Impact Development (LID) removal and treatment can be simulated at selected storage nodes. SWMM is one of the hydrology transport models which the EPA and other agencies have applied widely throughout North America and through consultants and universities throughout the world.

SWMM was first developed between 1969–1971 and has undergone several major upgrades since those years. The major upgrades were: (1) Version 2 in 1975, (2) Version 3 in 1981 and (3) Version 4 in 1988. The current SWMM edition, Version 5, is a complete re-write of the previous Fortran releases in the programming language C, and it can be run under Windows XP, Windows Vista and Windows 7 and with a recomplilation under Unix. The code for SWMM5 is open open source and public public domain code that can be downloaded from the EPA Web Site.

Broomfield, Colorado USA, March 26, 2013 — Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the release of the V3.5 Generation ofInfoWorks ICM. A comprehensive urban drainage modeling solution enabling users to work more efficiently and get the reliable information they need to make better design and operational decisions for optimal performance, InfoWorks ICM has rapidly become the solution of choice for integrated river, sewer and overland flow modeling among utilities, municipalities, local authorities and their consultants around the world. This release represents the leading edge in integrated, best-in-class smart catchment modeling for water utilities and river authorities. It incorporates many of the features requested by its global customer base — clear indication of the Innovyze commitment to providing its users with significant value and competitive advantages while quickly responding to their needs.

A hallmark of InfoWorks ICM is its dynamic integration of one-dimensional (1D) hydrodynamic simulation of flows in rivers, open channels and pipe networks and two-dimensional (2D) hydrodynamic simulation of surface flooding in the urban environment and river floodplain. The combination, achieved through an implicit coupling of 1D and 2D flow equations, provides a powerful solution for simultaneously modeling belowground and aboveground elements of catchments to accurately represent all flow paths and improve understanding of processes occurring in the holistic environment. The software also takes interactions of natural and man-made environments into account, and effectively simulates the impact of polluting runoff and effluent from urban areas on water quality.

Such advanced features give water utilities greatly enhanced capabilities for predicting flood risks; supporting cost-effective drainage design and management; developing online urban flooding forecasts; conceiving and evaluating sound and reliable urban catchment strategies such as storm sewer separation, active real-time control and provision of adequate additional storage; and improving drainage system operation.

InfoWorks ICM V3.5 delivers groundbreaking gains in speed, fidelity and productivity for both 1D and 2D simulations of large and complex models. It also provides direct support to all 2D structures, including bridges, as well as sophisticated 1D/2D breach (dam break) modeling. The 1D model is used to represent breach growth and flow, while the 2D model is used to predict flood propagation in the inundated areas. This integrated 1D/2D approach allows improved flood risk and damage evaluation and better assessment of effective mitigation measures. V3.5 also includes numerous improvements in river and water quality modeling as well as enhanced results presentation including comprehensive statistical reporting of 2D simulation results. New functionalities also include hydrogen sulfide modeling and support of the Federal Highway Administration inlet and access hole energy loss method (FHWA HEC 22) and scalar and spatial Time Series Databases (TSDBs).

Innovyze Releases ICM TSDB, Enabling Real-Time Data and Event Management

New Time-Series Database Allows Users to Transform Real-Time and Historical Data and Events into Actionable Information for Comprehensive Urban and Rural Catchment Modeling

Broomfield, Colorado, USA, February 19, 2013

Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced the worldwide release of ICM TSDB. For the first time, this revolutionary time-series database for industry-leading InfoWorks ICM lets utilities archive, analyze and aggregate real-time and historical data, including radar images and meteorological forecasts, into user-defined actionable information. They can then use this data to drive simulations of past and future events for optimal management of urban and rural catchment systems.

Despite the widespread availability and use of 2D rainfall data and time-series network data (e.g., rain gauge, level gauge, flow gauge), collection system models are not continuously updated with real-time field and radar data. Their applications are therefore generally confined to offline analyses. While such analyses can provide useful information for network design and long-range capital planning applications, they lack the predictive accuracy critical to operational and emergency event management. ICM TSDB provides accurate network performance and operational information from real-time data, enabling engineers and operators to quickly and reliably assess the integrity of the network and respond to potential overflows, flooding and other non-routine events.

ICM TSDB extends the utility of smart network modeling to encompass real-time field and radar data-driven simulations and predictive forecasting capabilities. It brings all relevant data from disparate sources into a single system readily available for detailed analysis using InfoWorks ICM. This enables operators to detect problems before they become events, and gives them crucial time to react and reduce or eliminate the impacts of these events. Such advanced capabilities greatly enhance the ability of wastewater utilities and river authorities to predict flood risks, support cost-effective drainage management and online urban flooding forecasts, and improve drainage system operation.

ICM TSDB delivers a powerful combination of 2D rainfall data and time-series data, along with a suite of analytic and visualization tools that monitor the performance and capacity of collection systems. It gives users a comprehensive, real-time view into current system operations, enabling them to make informed, timely decisions. ICM TSDB provides:

Flexible import, storage and export of time-series data including import from existing InfoWorks ICM events
Import, storage and export of 2D rainfall data on a range of geometries (both Cartesian and Polar) with a variety of source formats
Visualization and animation of 2D rainfall data
Creation, storage and management of user edits of time-series data
Addition of missing data or deletion/change of invalid data
Creation of custom overrides of the base data (what-if scenarios)
Merging of externally-supplied, user-edited and recurrent time series for input to a simulation or comparison with simulation results
Interpolation of time-series data at various stages in the data flow
Combination of rain gauge profiles and 2D rainfall profiles for direct simulation, including time-dependent prioritization of sources
Ability to use non-regular time steps for time-varying data (e.g., inflows, levels)
Seamless integration with any InfoWorks ICM model

“ICM TSDB elevates the standards for smart network modeling by enabling operational and engineering level integration throughout the utility organization,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President and Chief Operating Officer of Innovyze. “This critical software tool will allow utilities and river authorities to productively learn from past events as well as effectively monitor, forecast and better react to future events. These capabilities enable a new level of vulnerability assessment and collection system protection while reducing or eliminating property and environmental damages and safeguarding public health. This is another step in our ongoing commitment to delivering superior value to our customers who plan, design, manage, operate, and sustain safe, reliable water and wastewater infrastructure systems.”

Innovyze Releases BalanceNet for IWLive,
Next Generation of Real-Time Operations Optimization Software for Smarter Water Utilities

New Release Raises Bar for Energy Management and Sustainability Software,
Delivers Economic, Operational and Environmental Benefits

Broomfield, Colorado USA, February 12, 2013 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced the release of BalanceNetfor IWLive This new state-of-the-art real-time energy management and sustainability solution for drinking water distribution systems is designed to change the way water utility operators around the world make informed decisions on operating and managing their complex water networks to minimize energy costs and environmental impact while meeting production and performance requirements.

Water utilities are energy-intensive, and consumers use water in energy-intensive ways, like water heating and pressurizing. Approximately 80% of municipal water processing and distribution costs are for electricity, the vast majority of it consumed by pumps. In California, water-related energy use consumes roughly 20 percent of the state’s electricity, 30 percent of its natural gas, and 88 billion gallons of diesel fuel every year — and the demand is growing. Nationally, About 13 percent of U.S. electricity consumption is related to water, and the CO₂ embedded in the nation’s water represents 5% of all U.S. carbon emissions.

BalanceNet is designed expressly to assist water distribution system operators and train new operators in managing their energy consumption more effectively. It does so by equipping control rooms with the unprecedented real-time ability to develop sound, cost-effective pump scheduling policies that reduce operational and chemical costs, improve system performance and enable more reliable operations.

Designed for online applications with existing SCADA systems, BalanceNet reads real-time field data, instantly updates the network model and determines which pump and treatment plant schedules will yield the lowest operating cost while satisfying the desired system performance requirements (e.g., target tank trajectory curves, minimum and maximum flows and velocities, total pump flows). It uniquely combines an optimized mass balance model with an advanced network solver to quickly produce a set of near-ideal solutions for improving system operations. The network solver automatically defines the mass balance model, accounting for changes in demand, controls and other factors in each time step. The mass balance model is then optimized using Genetic Algorithms. Both energy consumption and pump switching costs are explicitly considered, and JET, Oracle, SQL and Pi databases are fully supported. The optimized pumping schedule can then be fed to the SCADA system for use in implementing resulting network control policies. These advantages represent fundamental advances in how readily water utilities operators can evaluate the efficiency of their water networks, then quickly and confidently develop improved system operations and more reliable performance.

“Since day one, our mission has been to bring powerful product development capabilities to the smart water network modeling community and foster its expansion,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE,Dist.D.NE, F.ASCE, President and Chief Operating Officer of Innovyze. “BalanceNet is a significant leap — an invaluable new water distribution systems planning and operations tool that will greatly aid utilities in improving the efficiency of their distribution systems and ensuring more reliable operations at maximum cost savings. This new software greatly enhances their ability to produce the best possible pumping schedules with minimum effort, reduced labor requirements and significant cost savings. The release demonstrates our strong commitment to continually delivering innovative technologies and superior value to our customers who manage, operate and sustain safe, reliable drinking water distribution systems. Innovyze is very proud to offer this revolutionary new power tool to the global waterworks industry.”

From the Dish - The Wisdom of Play

2013-02-10T20:32:55Z

The Wisdom Of Play

FEB 10 2013 @ 1:43PM

Mark Rowland meditates on the well-lived life, arguing that it “is play, and not work, that gives value to our lives”:

It might be that most of the things we do in life we do for the sake of something else. But there are still some things we do just to do them — for their own sake and not for the sake of anything else. If the former category is work, then the latter category is play. Work is activity directed at an external goal. Play is activity whose goal is internal or intrinsic to it. In its pure form, play has no external purpose or reward. We play just to play. When my sons’ volleys have been sufficiently consistent and accurate, their tennis coach will instigate a game. He yells, ‘Fruit basket!’ and lobs several balls into the air in quick succession. They have to drop their rackets, run and catch the balls before they stop bouncing. This is done amid much cackling and squeals of delight on their part — almost as if the rest of their lesson was work aimed at unleashing this bout of play. I love watching this, because I cannot imagine a purer form of play. There is no external goal or purpose. My sons do it simply because at that precise moment in time — and the squeals of delight are testament to this — there is nothing in the world they would rather be doing.

Innovyze Announces Release of ICMLive;
Real-Time Operational Forecasting of Urban and Rural Catchments

Revolutionary New Product Equips Water Utilities and River Authorities
with Unprecedented Decision-Making Capability

Broomfield, Colorado USA, February 05, 2013 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced the worldwide release ofICMLive for real-time operational forecasting of urban and rural catchments. The pioneering release provides water utilities timely, accurate and reliable forecasts of what will happen within a catchment, based on past and current observations of a multitude of parameters along with future rainfall predictions. The product combines the comprehensive integrated catchment modeling capabilities of InfoWorks ICM with sophisticated real-time operational forecasting, early warning, and emergency management. This debut reflects Innovyze’s vanguard position in the water industry and its ongoing commitment to delivering pioneering smart water solutions that enhance the safety, reliability and sustainability of the world’s wet infrastructure systems.

Advances in computer simulation and hardware have made real-time operation of stormwater, wastewater, river and combined systems a reality. ICMLive allows both large and small utilities and water authorities to manage their systems more efficiently and effectively than ever before. A powerful risk assessment and real-time decision making tool, it enables managers and operators to consider the influence of a full range of catchment factors in the management of flooding and the reduction of unregulated discharges; the optimization of storage and existing infrastructure, leading to savings on capital works; and the optimization of pumps to lower energy costs and reduce CO₂ emissions.

ICMLive is designed to work automatically. Once a system is configured, real-time data is continually and automatically harvested and quality checked. This data can be defined by a number of parameters, including observed and forecast radar rainfall, online water quality measurements, and ancillary structure and pump operation time series. Simulations are run automatically at a user-defined frequency using the full hydrodynamic and technological capabilities of InfoWorks ICM, including one- and two-dimensional modeling techniques, real-time control, dynamic water quality analysis, and GPU-enhanced and remote simulation. Simulation frequency can change in response to user-defined conditions. For example, increased rainfall intensity can trigger a reduction in the interval between simulations.

Warnings or alerts triggered during the forecast period are instantly displayed via the rich ICMLive user interface, allowing system operators to see at a glance which areas need attention and what options might be taken. Comparison alerts can be used to highlight differences between observed and modeled results, enabling users to refine their models — creating unprecedented confidence in simulation results.

ICMLive also allows operators to perform additional scenario analysis simulations, exploring alternative real time control scenarios, such as the impact of switching on a pump earlier than planned, and quickly seeing the effect of these changes on the system. The wide range of capabilities available in ICMLive allow it to be used as a key tool in the decision making process, enabling operators to take action to avoid system issues, release timely alerts, and quickly deploy response teams if necessary.

“Integrated catchment modeling is an invaluable tool for water utility planning, engineering and water quality departments,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President and Chief Operating Officer of Innovyze. “However, translating these benefits to real-time operations has proven difficult. With ICMLive, Innovyze has changed the paradigm for how and where integrated catchment models can be applied. This milestone solution gives engineering professionals the most advanced and comprehensive toolset available for planning, designing, operating and sustaining safe, reliable and efficient drainage systems while effectively protecting public health and our waterways.”

Ten years of cumulative precipitation

Ten years of cumulative precipitation

January 28, 2013 to Mapping by Nathan Yau

We've all seen rain maps for a sliver of time. Screw that. I want to see the total amount of rainfall over a ten-year period. Bill Wheaton did just that in the video above, showing cumulative rainfall between 1960 and 1970. The cool part is that you see mountains appear, but they're not actually mapped.

The hillshaded terrain (the growing hills and mountains) is based on the rainfall data, not on actual physical topography. In other words, hills and mountains are formed by the rainfall distribution itself and grow as the accumulated precipitation grows. High mountains and sharp edges occur where the distribution of precipitation varies substantially across short distances. Wide, broad plains and low hills are formed when the distribution of rainfall is relatively even across the landscape.

See also Wheaton's video that shows four years of rain straight up.

Is there more recent data? It could be an interesting complement to the drought maps we saw a few months ago. [Thanks, Bill]

Arizona Tourist Destination Selects InfoSWMM for Advanced Wastewater Network Modeling and Management

Decision Arms Bullhead City with Comprehensive GIS-Centric Solution for Managing its Sewer Infrastructure System

Broomfield, Colorado USA, January 22, 2013 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced that Bullhead City, Arizona, has selected the powerful smart drainage modeling solution InfoSWMM to implement system improvements based on the City’s Wastewater Master Plan. The purchase equips Bullhead City Public Works with comprehensive geospatial modeling technology that will allow it to better evaluate and optimize collection system operations and capacity.

Bullhead City, a community of 40,000 located 90 miles of south of Las Vegas in west-central Arizona, is a fast-growing regional tourism destination. It currently operates two major wastewater treatment plants, 15 sewer lift stations, and 190 miles of collection system. The Wastewater Master Plan was established to better address wastewater collection for the growing city. The City also intends to address effluent reuse system issues; plan for future collection, treatment and disposal; and identify, investigate and develop options for maximizing resources.

“Using this sophisticated technology to analyze and optimize our system will be a key factor in achieving our ultimate objectives,” said Bob Leuck, Assistant Public Works Director of Bullhead City. “InfoSWMM’s dependability, functionality and outstanding usability will empower us to better operate and sustain a safe and reliable wastewater system for our customers.”

InfoSWMM is a fully dynamic geospatial wastewater and stormwater modeling and management application that can be used to model the entire land phase of the hydrologic cycle as related to urban stormwater and wastewater collection systems. The model can perform single event or long-term (continuous) rainfall runoff simulations that account for climate, soil, land use, and topographic conditions of the watershed.

In addition to simulating runoff quantity, InfoSWMM can also predict runoff quality, including buildup and wash-off of pollutants from primarily urban watersheds. Once runoff quantity and quality are simulated and wastewater loads at receiving junctions are determined, the routing portion of InfoSWMM uses either steady routing, kinematic wave routing or dynamic wave routing to virtually transport this flow through a conveyance system of pipes, channels, storage/treatment devices, pumps, and hydraulic regulators such as weirs and orifices. The model also features a highly advanced Real-Time Control (RTC) scheme for the operational management of hydraulic structures.

“Bullhead City’s capital plan called for a cost-effective yet powerful tool to address its wastewater infrastructure needs,” said J. Erick Heath, P.E., Innovyze Vice President and Director of Americas Operations. “We are proud that progressive cities like this one continue to recognize our software as the best way to address their water and wastewater infrastructure concerns. We look forward to working with the City as it turns its capital plans into realities.”

Stopping Tolerance in InfoSWMM, H2OMAP SWMM and SWMM5 Internal Units

2013-01-18T02:39:00Z

Stopping Tolerance in InfoSWMM, H2OMAP SWMM and SWMM5 Internal Units

InfoSWMM, H2OMAP SWMM and SWMM 5 share the same underlying dynamic engine code but one small difference is that InfoSWMM and H2OMAP SWMM allows the user to select the node stopping tolerance instead of always using the default SWMM 5 stopping tolerance of 0.0005 feet. SWMM 5 uses internal units of feet and shows the output in meters if you are using SI units, as does InfoSWMM and H2OMAP SWMM. The following table shows how the stopping tolerance translates to inches and millimeters in the engine of a US and SI model. The smaller the tolerance the larger the number of iterations used during the simulation but using a very small tolerance does not always mean a better simulation. If possible, for example, with pumps it is better to use a small time step and a medium level tolerance – for example 1 millimeter is a good starting value, but maybe 2 or 3 millimeters may help if you have a continuity error at a pump node.

The nodes are considered converged if the depths between successive iterations is less than the stop tolerance of the program (the default stop tolerance is less than the stopping tolerance (Figure 1)


Stopping Tolerance	Inches	Millimeters
0.1000000	1.2000000	30.4800000
0.0500000	0.6000000	15.2400000
0.0100000	0.1200000	3.0480000
0.0050000	0.0600000	1.5240000
0.0001000	0.0012000	0.0304800
0.0005000	0.0060000	0.1524000
0.0000100	0.0001200	0.0030480
0.0000500	0.0006000	0.0152400
0.0000010	0.0000120	0.0003048
0.0000050	0.0000600	0.0015240
0.0000001	0.0000012	0.0000305

Figure 1 If the node depths between successive iterations are less than the stopping tolerance then the node is considered to be converged.

Importing a Link Shapefile into InfoSWMM via GIS Gateway

Importing a Link Shapefile into InfoSWMM via GIS Gateway

Here is how you map the shapefile pipe fields to the InfoSWMM data fields. One note, you had two diameter fields (feet and inches) and the feet column was mostly zero so I used the inch column. Here are the four steps and mapping you need to import all of the data from your shapefile. You will have to use blockedit and convert the diameter from inches to feet in the DB link table (Step 5 – note there are still three missing pipe diameters).

Step 1. Use the GIS Gateway command and set up the import of the file name, and ID field

Step 2. Set up the mapping between the Shapefile fields and InfoSWMM. We used link offset and the pipe diameter in inches.

Step 3. Load the mapped shapefile

Step 4. The imported data from your shapefile into the DB table of InfoSWMM

Step 5 Convert to feet from inches

Climate-proofing cities

Here's just one example, from Singapore:

RnD.de.PortraitsSingapore's Marina Barrage.

The Marina Barrage and Reservoir, which opened in 2008, is at the heart of Singapore's two-billion-dollar campaign to improve drainage infrastructure, reduce the size of flood-prone areas, and enhance the quality of city life. It has nine operable crest gates, a series of enormous pumps, and a ten-thousand-hectare catchment area that is roughly one-seventh the size of the country. The system not only protects low-lying urban neighborhoods from flooding during heavy rains; it also eliminates the tidal influence of the surrounding seawater, creating a rainfed supply of freshwater that currently meets ten percent of Singapore's demand. More over, by stabilizing water levels in the Marina basin the barriers have produced better conditions for water sports. The Marina's public areas, which include a sculpture garden, a water-play space, a green roof with dramatic skyline vistas, and the Sustainable Singapore Gallery, bolster the city's tourist economy as well.

That's a brilliant way to address two climate impacts -- large precipitation events and rising sea levels -- at once. Singapore has also elevated all access points to its underground subway a least a meter above high-water flood levels. It's also building desalination plants and systems to reuse waste water. It's also burying its power lines.

Engineers at the Dutch firm Arcadis recently proposed a large new sea barrier for north of New York City's Verrazano-Narrows Bridge. The price tag: $6.5 billion. And that's just one small piece of the puzzle. All this stuff is prudent, but it's expensive.

Singapore - Catching Every Drop of Rain

Singapore - Catching Every Drop of Rain

The source of the map of the rivers of Singapore is the Singapore PUB

As a small island that doesn't have natural aquifers and lakes and with little land to collect rainwater, Singapore needs to maximize whatever it can harvest.

Currently, Singapore uses two separate systems to collect rainwater and used water. Rainwater is collected through a comprehensive network of drains, canals, rivers and stormwater collection ponds before it is channelled to Singapore's 17 reservoirs for storage. This makes Singapore one of the few countries in the world to harvest urban stormwater on a large scale for its water supply.

The newest reservoirs are Punggol and Serangoon Reservoirs which are our 16th and 17th reservoirs. By 2011, the water catchment area has increased from half to two-thirds of Singapore’s land surface with the completion of the Marina, Punggol and Serangoon reservoirs.

With all the major estuaries already dammed to create reservoirs, PUB aims to harness water from the remaining streams and rivulets near the shoreline using technology that can treat water of varying salinity. This will boost Singapore’s water catchment area to 90% by 2060,

The goal is to capture every drop of rain (Figure 1)

Advances in artificial intelligence: deep learning

Advances in artificial intelligence: deep learning

November 25, 2012 – 12:34 am

If you want to keep up with advances in artificial intelligence, the New York Times has an essentialarticle on a recent step forward called deep learning.

There is a rule of thumb for following how AI is progressing: keep track of what Geoffrey Hinton is doing.

Much of the current science of artificial neural networks and machine learning stems from his work or work he has done with collaborators.

The New York Times piece riffs on the fact that Hinton and his team just won a competition to design software to help find molecules that are most likely to be good candidates for new drugs.

Hinton’s team entered late, their software didn’t include a big detailed database of prior knowledge, and they easily won by applying deep learning methods.

To understand the advance you need to know a little about how modern AI works.

Most uses abstract statistical representations. For example, a face recognition system will not use human-familiar concepts like ‘mouth’, ‘nose’ and ‘eyes’ but statistical properties derived from the image that may bear no relation to how we talk about faces.

The innovation of deep learning is that it not only arranges these properties into hierarchies – with properties and sub-properties – but it works out how many levels of hierarchy best fit the data.

If you’re a machine learning aficionado Hinton described how they won the competition in a recent interview but he also puts all his scientific papersonline if you want the bare metal of the science.

Either way, while the NYT piece doesn’t go into how the new approach works, it nicely captures it’s implications for how AI is being applied.

And as many net applications now rely on communication with the cloud – think Siri or Google Maps – advances in artificial intelligence very quickly have an impact on our day-to-day tools.

Innovyze Announces SCADAMaster for Smart Water Grids, Enabling Real-Time Management and Viewing of SCADA Information

Innovyze Announces SCADAMaster for Smart Water Grids, Enabling Real-Time Management and Viewing of SCADA Information New Product Allows Users to Seamlessly Connect Telemetry Data to Their Innovyze Product Suites

Broomfield, Colorado USA, December 18, 2012 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced the worldwide release of SCADAMaster. This new real-time network data management tool for water distribution and sewer collection systems turns traditional offline analyses into extremely accurate, high-fidelity online network simulations — giving utilities the most cost-effective way of viewing and synthesizing SCADA and other real time telemetry data with network modeling and other enterprise applications. Despite the widespread availability and use of Supervisory Control and Data Acquisition (SCADA) or equivalent telemetry systems, water distribution and sewer collection network models are not continuously updated with real-time field data and their applications are generally confined to offline analyses. While these analyses can provide useful information for network design and long-range capital planning applications, they lack the predictive accuracy critical for operational and emergency event management. SCADAMaster provides accurate network performance and operational information from real-time data enabling control room operators to quickly and reliably assess the integrity of the network and respond to upsets, failures, and other non-routine situations. SCADAMaster extends the utility of smart network modeling to encompass real-time, field data driven simulations and predictive forecasting capabilities. It can be configured in a “read only” mode or one that enables bidirectional communication. When used in conjunction with IWLive and BalanceNet, the solution suite can provide optimized control schemes to the control room for operational review, or send them directly to the SCADA system. This powerful setup enables problems to be detected before they become events, and reduces the risk of system or performance failure. SCADA systems give utilities real time information about the status of their collection and distribution systems. Most SCADA systems are optimized to provide fast and reliable data directly to the control room — not to the planning level for decision support. SCADAMaster fills this void by cost effectively linking via an OPC UA/DA client to an existing OPC Server via a secure connection and warehousing the data in a configurable SQL Server relational database. SCADAMaster users decide which tags are polled and at what frequency, and are free to design a data warehouse that best fits their organizational needs. (OPC is the most widely used standard for collaboration by a number of leading worldwide automation suppliers working in cooperation with Microsoft. Originally based on Microsoft’s OLE COM [component object model] and DCOM [distributed component object model] technologies, OPC was created to facilitate interoperability by defining a standard set of objects, interfaces and methods for process control and manufacturing automation applications.) “SCADAMaster opens new doors to operational- and engineering-level integration throughout the utility organization,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President and Chief Operating Officer of Innovyze. “This critical software tool will allow utilities to cost effectively bring the power and accuracy of real-time field data to their water enterprises and jumpstart smart water projects, making the distribution and collection of water more efficient and reliable. It’s another step in our ongoing commitment to delivering superior value to our customers who plan, design, manage, operate, and sustain safe, reliable water and wastewater infrastructure systems.”

Chana Joffe-Walt examines Lego's dominance despite their products' high cost and lack of exclusive patent:

Lego goes to great lengths to make its pieces really, really well, according to David Robertson, who is working on a book about Lego. Inside every Lego brick, there are three numbers, that identify exactly what mold the brick came from, and what position it was in in that mold. That way, if there's a bad brick somewhere, the company can go back and fix the mold. For decades this is what kept Lego ahead. It's actually pretty hard to make millions of plastic blocks that all fit together.
