Computer application determines optimal green infrastructure strategies
Innovyze announced worldwide availability of the V2.0 Generation of its InfoSWMM Sustain for comprehensive urban storm water treatment and analysis. The new version lets users quickly and reliably determine optimal green infrastructure strategies for reducing volume and peak flows to combined sewer systems as well as evaluating the benefits of distributed green infrastructure implementation on water quantity and quality in urban streams.
InfoSWMM Sustain is a comprehensive geocentric decision support system created to assist storm water management professionals in developing and implementing plans for flow and pollution control measures to protect source waters and meet water quality goals. The software lets users locate, develop, evaluate and select optimal BMP, low impact development (LID) and Sustainable Urban Drainage Systems (SUDS) combinations at various watershed scales based on cost and effectiveness. It can accurately model any combination of LID controls, such as porous permeable pavement, rain gardens, green roofs, street planters, rain barrels, infiltration trenches and vegetative swales to determine effectiveness in managing storm water and combined sewer overflows.
Also, InfoSWMM Sustain automaticallys assesses the geographic properties in the study area including soil properties, land use, slope, building footprint, groundwater, land ownership and imperviousness to determine all possible locations of feasible green infrastructure alternatives. These expanded capabilities can assist users in developing cost-effective and reliable implementation plans for flow and pollution control aimed at protecting source waters and meeting water quality goals. They do so by helping users answer crucial questions: How effective are BMPs in reducing runoff and pollutant loadings? What are the most cost-effective solutions for meeting water quality and quantity objectives? Where, what type and how extensive should BMPs be?
By seamlessly integrating ArcGIS 10.x (Esri, Redlands, CA) with SWMM 5.1, InfoSWMM Sustain expands and improves on the USEPA SUSTAIN software to provide needed support to watershed practitioners at all levels in developing storm water management evaluations and cost optimizations to meet their program needs. The software can automatically import any SWMM 5.1, InfoSWMM or InfoWorks ICM (exported to SWMM 5.1) model, then evaluate numerous potential combinations of BMPs and LIDs to determine the optimal combination to meet specified objectives such as runoff volume or pollutant loading reductions. Both kinematic wave and full dynamic wave flow routing models are fully supported. Among its many vital applications, InfoSWMM Sustain can be used in developing TMDL implementation plans, identifying management practices to achieve pollutant reductions under a separate municipal storm sewer system (MS4) storm water permit, determining optimal green infrastructure strategies for reducing volume and peak flows to combined sewer systems, evaluating the benefits of distributed green infrastructure implementation on water quantity and quality in urban streams, and developing a phased BMP installation plan using cost effectiveness curves.
Among its many major enhancements, Version 2.0 lets users optimize the entire system using advanced genetic algorithms, not just individual subcatchments. Users can also choose a systemwide budget constraint and reduction target for runoff and pollution, compare hydrographs for runoff and pollutants of the various solutions on the Cost Effectiveness Curve, implement desired LID design solution in InfoSWMM, and display the optimal systemwide runoff and pollutant reduction. The new release also introduces an improved interface that visually highlights and simplifies the workflow process. Users can now evaluate complex decisions about green infrastructure selection and placement performance, costs for meeting flow or water quality targets, or both.
“With InfoSWMM Sustain, we are extending our success in the smart network modeling marketplace to address the specific needs of stormwater management professionals and their engineering consultants,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, Dist.M.ASCE, NAE, President, COO and Chief Technical Officer of Innovyze. “The new release performs very sophisticated hydrologic and water quality modeling in watersheds and urban streams, and enables users to determine optimal management solutions at multiple-scale watersheds to achieve desired water quality objectives based on cost effectiveness. It also gives users the power tool they need to maximize water quality benefits, minimize storm water management costs and combined sewer overflows, and protect the environment and public health. This is a must-have for predicting the environmental outcomes of different design and management approaches as well as developing optimal plans for flow and pollution control to protect source waters and meet water quality goals.”
