Innovyze announced the worldwide availability of the V13 Generation of its industry-leading InfoSWMM 2D for ArcGIS (Esri, Redlands, CA). InfoSWMM 2Ddelivers new ways to quickly and accurately build and analyze very large and comprehensive two-dimensional (2D) models that reliably simulate complex urban stormwater, sanitary sewers, river flooding and pollutant transport. It allows users to accurately predict the extent and duration of urban and rural flooding for comprehensive stormwater management directly within the powerful ArcGIS environment.
A fully hydrodynamic geospatial stormwater modeling and management software application, InfoSWMM 2D can be used to model the entire land phase of the hydrologic cycle as applied to urban stormwater systems. Built atop ArcGIS and using exceptionally robust and efficient numerical simulation capabilities, the model can perform single-event or long-term (continuous) rainfall/runoff simulations accounting for climate, soil, land use, and topographic conditions of the watershed. In addition to simulating runoff quantity, InfoSWMM 2D can reliably predict runoff quality, including buildup and washoff of pollutants from primarily urban watersheds. It also features very sophisticated Real-Time Control (RTC) schemes for the operational control and management of hydraulic structures.
A hallmark of InfoSWMM 2D is its dynamic integration of one-dimensional (1D) hydrodynamic simulation of flows in open channels, HEC-22 inlets and closed pipe networks with two-dimensional (2D) hydrodynamic simulation of surface runoff, evaporation, infiltration and flooding in the urban environment. The dynamic integration, achieved through an explicit coupling of 1D and 2D flow equations, provides a powerful solution for simultaneously modeling belowground and aboveground elements of watersheds to accurately represent all flow paths and improve understanding of holistic processes. InfoSWMM 2D also directly simulates the rainfall and infiltration on both the watershed and the 2D surface to better simulate 1D flooding, 2D surface flooding, 2D shallow groundwater recharge and complex 1D and 2D surface interactions.
The full 2D free-surface shallow water equations are solved using a highly advanced finite volume method, which is particularly suitable for rapidly varying flood flows such as those moving through steep streets and road junctions and those associated with bank overtopping or breaching. The unparalleled 1D/2D dynamic linking capabilities of InfoSWMM 2D give engineers the unprecedented power to analyze and predict potential flood extents, depth and velocity and accurately model the interaction of surface and underground systems in an integrated 1D/2D environment. The software can be used to simulate point sources, 2D boundaries, multiple 2D mesh and simulation polygons in a sewer or stormwater network. The combined water level and velocity results throughout the flooded areas can be viewed as various comprehensive graphs; tables; or animated, thematic flood maps.
Among its many new enhancements, Version 13 uses a significantly improved 2D simulation engine, the flexible InfoSWMM ArcMap polygon tools, a 1D InfoSWMM engine based on the latest EPA SWMM 5.1, a new 1D and 2D graphics engine and a comprehensive Output Report Manager and Statistical Event Manager for both 1D and 2D output. In addition, the new release allows users to instantly visualize the maximum extent of flooding in vivid 2D and 3D maps.
“We’re deeply committed to providing a geospatial modeling experience that is both intuitive and powerful, and InfoSWMM 2D V13 embodies that commitment,” said Paul F. Boulos, Ph.D., BCEEM, NAE, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “This release delivers major geotechnological and computational enhancements in short release cycles to make sure our customers are always equipped with the ultimate ArcGIS-centric decision support tool for stormwater and urban drainage systems. It greatly extends the core features of InfoSWMM, providing the most powerful and comprehensive ArcGIS-centric tool kit ever for managing the risks of urban and rural flooding. This is a must have for effectively controlling and managing sanitary sewer and combined sewer overflows.”
