   This User’s guide to SWMM5 has been compiled from earlier sources as an interim measure, to bridge the gap until a complete SWMM5 manual, with theoretical background, is released (now way overdue).  This 13th edition, 905-page manual has been reduced in size from the or... [More]

PCSWMM 2D flood forecasting system RELEASE DATE: PCSWMM 2011 2D is scheduled to be released in late 2011.      PCSWMM 2D modeling - wave reflectivity off obstructionsThis video demonstrates PCSWMM 2011 2D modeling of wave reflectivity off obstr... [More]

October 15, 2010 - PCSWMM 2011 is now available and new features include improved transferring of graphical data, a new anti-aliasing function in the graph panel and a new time series window.  PCSWMM 2011 now supports the newest version of US EPA SWMM (Version 5.0.021) which now features a new ...

I am very excited to introduce the documentation panel, one of the newest features of PCSWMM. The purpose of this panel is to keep an ongoing inventory of all the files that are frequently used in the construction of a PCSWMM model. From my own experience I can say that the addition of the documen... [More]

Viewing and animating multiple profiles/HGLs simultaneously can aid in the analysis and presentation of many modeling projects. One prime example is in dual drainage (major/minor) system analysis, where the simultaneous plotting of both major and minor system HGLs allows the user to see the dynamic ... [More]

In version 3.9 of PCSWMM 2010 Standard and Professional, we have release some significant new features which are documented in other posts. However, we often do not mention the small changes that improve the aesthetics of the maps, graphs and profiles that PCSWMM produces. In this post I wanted to h... [More]

This update adds some exciting new tools, as well as many incremental improvements to the software which are designed to increase workflow efficiency, improve automated processes and make the software more intuitive. There are a couple of changes to core functionality that you should be aw... [More]

CHI has introduced an advanced easy-to-use tool for importing river models from HEC-RAS (version 4.0 and earlier) into PCSWMM for modeling with the EPA SWMM5 dynamic wave, kinematic wave or steady-state routing methods. Simply select the geometric file you wish to import, and PCSWMM automatically im... [More]
