Broomfield, Colorado USA, May 19, 2010 — MWH Soft, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced the worldwide availability of InfoSWMM 2D, a powerful, highly-advanced geospatial modeling solution for building and analyzing comprehensive 2D models that simulate urban stormwater, sanitary sewers, river flooding and pollutant transport. The breakthrough application allows engineers to accurately model two-dimensional (2D) above-ground urban and rural flooding combined with the power of one-dimensional (1D) hydraulic and water quality sewer systems analysis — all directly within the powerful ArcGIS (ESRI, Redlands, CA) environment.

The new product demonstrates MWH Soft’s ongoing commitment to delivering pioneering technology that raises the bar for urban drainage network modeling and simulation, helping to shape the future of this critical sector. It gives wastewater utilities the flexibility to continue to use InfoSWMM, the industry’s premier ArcGIS-centric urban drainage modeling solution, while gaining new power to predict the extent and duration of urban and rural flooding for comprehensive stormwater management.

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. 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 2Dcan 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.

Built atop ArcGIS and using exceptionally robust and efficient numerical simulation capabilities, InfoSWMM 2Dseamlessly integrates advanced 1D and 2D functionalities in one environment, enabling users to 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 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, which is particularly suitable for rapidly varying flood flows such as those through steep streets and road junctions and those associated with bank overtopping or breaching. The unparalleled 1D/2D dynamic linking capabilities ofInfoSWMM 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 also be effectively used to simulate and analyze tidal surges, dam breaks and breaches on sewer networks. The combined water level and velocity results throughout the flooded areas can be viewed as graphs, tables or animated, thematic flood maps.

“InfoSWMM 2D greatly extends the core features of InfoSWMM, providing the most powerful and comprehensive ArcGIS-centric tool kit ever for managing the risks of flooding,” said Paul F. Boulos, Ph.D., Hon.D.WRE, F.ASCE, President and COO of MWH Soft. “This milestone solution marks a new direction in advanced sewer collection systems simulation and analysis. It is the only GIS-centric analysis, design and management software users need to work faster and smarter in a competitive environment — not only to power system performance, but to safeguard critical wet infrastructures and maximize their effectiveness in protecting public health. This is the ultimate tool for accurately assessing the impacts of urban and rural flooding, then formulating and evaluating sound and cost-effective mitigation strategies. MWH Soft is very proud to offer this revolutionary product to our clients.”
