Drainage and Flooding

InfoSWMM is a highly advanced and comprehensive GIS-centric hydrologic, hydraulic, and water quality simulation model for the management of urban stormwater drainage and wastewater collection systems. It can be used to model the entire land phase of the hydrologic cycle. Built atop Esri’s ArcGIS, InfoSWMM seamlessly integrates advanced hydrologic and sewer collection system modeling and optimization functionality, enabling users to leverage existing GIS investments in one complete and affordable package.

ARCGIS INTEGRATED URBAN DRAINAGE NETWORK MODELING

APPLICATIONS

• Design and size drainage system components for flood control

• Size detention facilities and their appurtenances for flood control and water quality protection

• Map flood plains of natural channel systems

• Design control strategies for minimizing sanitary and combined sewer overflows

• Evaluate the impact of inflow and infiltration on sanitary and combined sewer overflows

• Generate non-point source pollutant loadings for waste load allocation studies and TMDLs

• Assess reduction in constituent concentration through treatment in storage units or by natural processes in pipes and channels

• Control site runoff using LID practices

• Evaluate the effectiveness of BMPs for reducing wet weather pollutant loadings

• Master plan sewer collection systems and urban watersheds

• Analyze hydrogen sulfide generation and corrosion in sewers

• Model sediment transport and deposition

• Estimate the production of pollutant loads associated with stormwater runoff

• Route water quality constituents through the drainage system

• Model future climate change projections

UNEQUALED GEOSPATIAL HYDROLOGIC MODELING CAPABILITIES

InfoSWMM performs dynamic rainfall-runoff simulations for single event or long-term (continuous) simulations accounting for climate, soil, land use and topographic conditions of the watershed. The runoff component operates on a collection of subcatchment areas onto which rain falls and runoff is generated. It can account for various hydrologic processes that produce runoff from urban areas including time-varying rainfall, rainfall interception, infiltration and percolation, evaporation, snow melt, flow between groundwater and the conveyance system, dry weather sanitary flows, user-defined flows and reservoir routing of overland flow.

POWERFUL & VERSATILE HYDRAULIC MODELING FEATURES

With the ability to handle networks of any size, InfoSWMM includes flexible hydraulic modeling features used to route runoff and external inflows through a network of pipes, channels, pumps, storage and treatment units and diversion structures. It accurately models various flow regimes, such as backwater, surcharging, reverse flow, and surface ponding. Once the runoff quantity and quality are simulated and wastewater loads at receiving junctions are determined, flows are routed using kinematic or full dynamic wave routing. Users have complete real-time control of the operation of all hydraulic structures. They can specify dynamic control rules to simulate the operation of pumps, links, nodes, orifice openings, and weir crest levels. InfoSWMM also supports a variety of specialized treatment plant control devices as well as river profiles resulting in an Integrated Catchment Management solution for modeling the sewer system, the receiving water and the wastewater treatment plant in an integrated manner.

COMPREHENSIVE WATER QUALITY CAPABILITIES

In addition to modeling the generation and transport of runoff flows, InfoSWMM can also estimate the production, fate and treatment of pollutant loads associated with this runoff. For any number of water quality constituents, a comprehensive range of processes can be simulated including dry weather pollutant buildup based on land use, pollutant wash-off during storm events, dry weather entry of sanitary flows, and reduction in dry weather loads due to BMPs.

RICH PRESENTATION OF RESULTS

Using powerful ArcGIS thematic mapping functionality, InfoSWMM makes it easy to turn dry database information into stunningly colorful, fully dimensional visualizations. Users can generate beautiful, accurate and smooth contours for any variable, including HGL or water quality — even overlay multiple contours on a single drawing. Users can draw on a range of other sophisticated graphical presentation tools, including color-coded mapping, dynamic annotation/labeling, graphing, profiling, customizable tabular reporting, and vivid VCR-style animation to produce truly compelling results.

COMPREHENSIVE LOW IMPACT DEVELOPMENT FUNCTIONALITY

InfoSWMM offers comprehensive Low Impact Development (LID) Controls functionality. LID Controls are low impact development practices designed to capture surface runoff and provide some combination of detention, infiltration, and evapotranspiration to it. InfoSWMM can explicitly model eight different generic types of LID controls. These are: bio-retention cells, infiltration trenches, continuous porous pavement systems, rain gardens, green roofs, rooftop disconnections, rain barrels (or cisterns) and vegetative swales. Bio-retention cells, infiltration trenches, and porous pavement systems can all contain optional underdrain systems in their gravel storage beds to convey captured runoff away from the site rather than letting it all infiltrate. They can also have an impermeable floor or liner that prevents any infiltration into the native soil from occurring. Infiltration trenches and porous pavement systems can also be subjected to a decrease in hydraulic conductivity over time due to clogging.

EPA SWMM-CAT SUPPORT

InfoSMWM supports the newly released USEPA Storm Water Management Model Climate Adjustment Tool (SWMM-CAT). This important capability allows users of InfoSWMM to directly estimate future changes in temperature, evaporation and rainfall for simulation modeling.
