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.

Innovyze Press Release

InfoWorks ICM V3.5 Launches New Era of Smart Integrated Catchment Modeling
Major Advances in New Release Deliver Today’s Best-in-Class Solution
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

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.”
