InfoSWMM 2D Version 5.0 Delivers New Level of Surface Mesh Automation and Faster, Higher-Fidelity Simulation Results

InfoSWMM 2D delivers new ways to quickly and accurately build and analyze large and comprehensive two-dimensional (2D) models that reliably simulate urban stormwater, sanitary sewers, river flooding and pollutant transport. Users can accurately predict the extent and duration of urban and rural flooding, giving them comprehensive stormwater management directly within the powerful ArcGIS environment.

 

A fully hydrodynamic geospatial stormwater modeling and management software application, InfoSWMM 2D can model the entire land phase of the hydrologic cycle as applied to urban stormwater systems. 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 sophisticated Real-Time Control (RTC) schemes for the operational control and management of hydraulic structures.

 

Built atop ArcGIS and using exceptionally robust and efficient numerical simulation capabilities, InfoSWMM 2D seamlessly integrates advanced 1D and 2D functionalities into one environment. Users can model the most complex storm and combined sewer collection systems and surface flooding with incredible ease and accuracy.

 

When overland flows are routed through a complex urban area or highly varied terrain, the numerous elevation changes and obstacles can significantly impact modeling results. This problem can be further complicated by the presence of sewer networks, where flows can both enter and exit the system during flood events. With InfoSWMM 2D, users can employ 1D simulation to identify the location of flooding and 2D simulation to investigate the direction and depth of flood flows in specific areas.

 

The full 2D free-surface shallow water equations are solved using a highly advanced finite volume method. This is particularly suitable for rapidly varying flood flows, such as those through steep streets and road junctions, as well as 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, as well as depth and velocity. Engineers can also accurately model the interaction of surface and underground systems in an integrated 1D/2D environment. The software can simulate point sources, 2D boundaries, and multiple 2D mesh and simulation polygons in a sewer or stormwater network. Even better, the combined water level and velocity results throughout the flooded areas can be viewed as various comprehensive graphs, tables or even animated thematic flood maps.

 

Version 5.0 delivers new benefits in three major areas: (1) Higher productivity via a new fully automated surface mesh generation scheme and log file; (2) Greater fidelity via an improved surface mesh solver that can automatically detect and correct many types of problems, including duplicate vertices and segments, overlapping segments and crossing of 2D elements with 2D boundaries; and (3) Performance modeling with significantly greater computational speed.

 

“We’re deeply committed to providing a geospatial modeling experience that is both intuitive and powerful, and InfoSWMM 2D V5.0 embodies that commitment,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, F.ASCE, President and Chief Operating Officer of Innovyze. “This release delivers major geotechnological and computational enhancements in a short release cycle 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 toolkit ever for managing the risks of urban and rural flooding.”
