Everyone Should Write

Everyone Should Write

Says James Somers:

You should write because when you know that you’re going to write, it changes the way you live. I’m thinking about a book I read called Field Notes on Science & Nature, a collection of essays by scientists about their notes. It’s hard to imagine a more tedious concept — a book of essays about notes? — but in execution it was wonderful. What it teaches you, over and over again, is that the difference between you and a zoologist or you and a botanist is that the botanist, when she looks at a flower, has a question in mind. She’s trying to generate questions. For her the flower is the locus of many mental threads, some nascent, some spanning her career. Her field notebook is not some convenient way to store lifeless data to be presented in lifeless papers so that other scientists can replicate some dull experiment; it’s the site of a collision between a mind and a world.

More interesting insight:

When I have a piece of writing in mind, what I have, in fact, is a mental bucket: an attractor for and generator of thought. It’s like a thematic gravity well, a magnet for what would otherwise be a mess of iron filings. I’ll read books differently and listen differently in conversations. In particular I’ll remember everything better; everything will mean more to me. That’s because everything I perceive will unconsciously engage on its way in with the substance of my preoccupation. A preoccupation, in that sense, is a hell of a useful thing for a mind.

Weekend DWF Patterns in H2OMAP SWMM and InfoSWMM

Dry Weather Flow in InfoSWMM and H2OMap SWMM

 

Dry weather flow can be added to any node in H2OMAP SWMM.  The dry weather flow is computed as the average flow * the monthly pattern * the daily pattern * hourly pattern * the weekend daily pattern to give the Dry Weather Flow at any time step (Figure 1).   Since the four types of patterns (Figure 2) are all multiplied together then for Saturday and Sunday the hourly pattern and the weekend hourly pattern will both be used.   This will have the effect of overestimating the flow if the multipliers are greater than 1 and underestimating the flow if the multipliers are less than one.  You should enter the  Pattern X for the Weekend Hourly Pattern in H2OMAP SWMM  where

 

X  = Weekend Hourly Pattern / Hourly Pattern

 

So that when the pattern X is multiplied by the Hourly Pattern the program will use the intended Weekend Pattern.

City of Toledo Adopts Innovyze Smart Water Network Modeling Solution

InfoWater Selected to Support Comprehensive Geospatial Water System Management 

 

Broomfield, Colorado USA, October 30, 2012 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced that the City of Toledo, Ohio, has chosen the company’s industry-leading InfoWater software as its advanced water distribution modeling and maintenance solution. With this purchase, Toledo gains a full range of high-performance ArcGIS-centric (Esri, Redlands, CA) smart water network asset modeling and management capabilities that will keep its water system functioning at peak performance levels and with maximum service reliability and value.

The fourth-largest municipality in the state of Ohio, the City of Toledo is responsible for providing safe drinking water to more than 454,000 customers in the greater metropolitan area via a water system that comprises 1,100 miles of pipeline and 10,000 fire hydrants. Toledo will use InfoWater as the basis for developing a comprehensive GIS-based solution for modeling and managing its drinking water infrastructure and optimizing its capital improvement projects.

“InfoWater software has the ideal combination of power, functionality, GIS integration, and capabilities we need to support our enterprise-wide GIS network modeling and management activities,” said Scott Sibley, Administrator – Utility Engineering for the City of Toledo. “These advantages, along with InfoWater’s excellent training and technical support, will help insure our ability to accurately model our system for years to come.”

Built atop ArcGIS, InfoWater seamlessly integrates sophisticated analytics, systems dynamics, and optimization functionality directly within the ArcGIS setting. The InfoWater product suite comes equipped with everything water utility owner–operators need to best design, operate, secure, and sustain their distribution systems — from fire flow and water quality simulations, valve criticality, and energy cost analysis to pressure zone management and advanced Genetic Algorithm and Particle Swarm optimization. In addition, the software serves as a base platform for advanced smart network modeling, operational, capital planning, and asset management extensions. These critical applications include IWLive (real-time operations and security), InfoWater UDF (unidirectional flushing), CapPlan (risk-based capital planning), InfoMaster and InfoMaster Mobile (asset integrity management and condition assessment), InfoWater MSX (multispecies, temperature, and particle transport/deposition modeling), InfoWater BTX (event/particle backtracking), InfoSurge (surge/transient analysis), and Sustainability (carbon footprint calculation).
