With a single button click, you can create incredibly evocative presentations with animated 3-D rendering of the flooding in Google Earth. This means that there is no measureable post-processing – SWMM5 computed time series results are immediately available, and thus you can even animate the flood inundation polygon on-the-fly in PCSWMM and/or in Google Earth. The amazing thing about this approach is that PCSWMM automates the entire process and creates the flood inundation polygons (one per river reach) on-the-fly in less than one hundredth of a second.
generate channel length-interpolated water surface elevation data and create a flood inundation polygon from a DEM layer. execute a single event or continuous EPA SWMM5 run using the dynamic, kinematic or steady state routing methods,. generate individual subcatchment input hyetographs (either continuous or single event) from ground-truthed radar rainfall (more on this later) using PCSWMM radar acquisition and processing tools,. import the watershed hydraulics (natural channel conveyance system) from HEC-RAS (using the PCSWMM HEC-RAS import tool) or build your own SWMM5 model from GIS and DEM data (more on this later),. PCSWMM Professional introduces the ability to generate flood inundation polygons and perform flood vulnerable asset analysis from EPA SWMM5 computed results. I’ll briefly highlight each of the tools here. The most significant new features include: flood inundation tools, DEM data processing, comprehensive NEXRAD radar-rainfall processing tools, and powerful reporting tools (including enhanced integration of Excel, Access and SQL Server). There are a number of cool new features which select clients have been using and providing feedback on over the past 2 years – we’ve bundled them together to create a Professional version and made available to all. I’m pleased to report the general availability of PCSWMM 2009 Professional, our flagship software for advanced watershed, stormwater and wastewater modeling.
