July 19, 2007

Computational Hydraulics Int. (CHI) has released the latest upgrade of its GIS-based, PCSWMM.NET graphical decision support system for US Environmental Protection Agency (EPA) Storm Water Management Model (SWMM5) urban drainage modeling (sanitary, storm and/or combined systems). PCSWMM.NET has been redeveloped from the ground up with GIS functionality from the TatukGIS Developer Kernel toolkit (.NET edition). Working seamlessly with the latest GIS data formats, PCSWMM.NET implements advanced, intelligent tools for streamlining sewer collection system model development, optimization, and analysis. With full support for the US EPA SWMM5 hydrology/hydraulics engine, PCSWMM.NET provides a scaleable (unlimited model sizes) and complete array of professional, enterprise level, urban drainage system modeling tools for an affordable price.

With over 3000 licenses sold, PCSWMM has been the leading decision support system for US EPA SWMM since it's inception in 1984 and has been applied in thousands of sewer and storm water studies throughout the world (over 50 countries). Now PCSWMM.NET is the also most powerful urban drainage modeling application for working with GIS/CAD based data. PCSWMM.NET enables both engineers and GIS professionals to work on the same data, improving workflow and increasing the flexibility of any model building and analysis toolset. PCSWMM.NET supports the leading open standard and proprietary GIS and CAD formats, including Geomedia SQL, MapInfo, Microstation, AutoCAD, GML, OpenGIS SQL, KML and many others (over 30 vector and raster formats supported), providing the flexibility to choose the SWMM data storage format that's right for any customer situation. PCSWMM.NET's high-performance, scaleable GIS engine also provides powerful GIS analysis and hydraulic modeling in a single stand-alone environment, with no other third-party licenses required. Users can now create, edit, modify, run, map, analyze, design and optimize GIS based sewer network models and instantly review, query and display simulation results either from within the specialized and optimized PCSWMM.NET interface or from within ArcGIS or another GIS of choice.

 

High-performance and scaleable GIS analysis and hydraulic modeling in a single stand-alone environment. Create, edit, modify, run, map, analyze, design and optimize GIS based sewer network models and review, query and display simulation results.
 

Area weighting operations are provided for any polygon layer representing SWMM5 subcatchments or sewersheds. This is useful for radar-rainfall integration and soil map infiltration parameter computations.

 

Typical applications of PCSWMM include:  


  • design and sizing of drainage system components for flood control
     
  • sizing of detention facilities and their appurtenances for flood control and water quality protection
     
  • designing control strategies for minimizing combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs)
     
  • evaluating the impact of rainfall-dependant inflow and infiltration (RDII) on sanitary sewer overflows and water-in-basements (WIBs)
     
  • dual-drainage (major/minor system) modeling and design, including dynamic interaction of dual systems
     
  • evaluating global optimal and/or passive real-time control (GO RTC) operational strategies
     
  • flood plain mapping of natural channel systems
     
  • integrated catchment/watershed management modeling, including rural areas, river systems, urban sewer systems, treatment plants and receiving waters
     
  • generating non-point source pollutant loadings for waste load allocation studies
     
  • evaluating the effectiveness of best management practices (BMPs) and/or low impact developments (LIDs) for reducing wet weather pollutant loadings
     
  • evaluating strategies for NPDES Permits, CMOM, and TMDL requirements.

Dynamic hydraulic grade line (DHGL) provides ability to see cross-connections, representation of natural channels, plotting of the energy grade line (EGL), plotting of storage tanks and ponds, and to graphically edit the entities (node inverts, depths, conduit lengths, diameters, offsets, etc.).
 

Flexible hydraulic modeling capabilities used to route runoff, RDII, DWF, and/or external inflows through the drainage system network of pipes, channels, storage/treatment units and diversion structures.
 

Time pattern creation for dry weather flow (DWF) analyzer tool allows for the instant creation of hourly, daily, and/or monthly patterns for sanitary sewer DWF model inputs.
