EPA is happy to announce the publication of Volume II of the #SWMM Reference Manual (Hydraulics)

Hello Everyone (from the @CHI SWMM List Server),

EPA is happy to announce the publication of Volume II of the SWMM Reference Manual (Hydraulics).  It can be viewed and downloaded from the EPA SWMM web page:
https://www.epa.gov/water-research/storm-water-management-model-swmm#documents

This completes the full set of reference manuals for SWMM 5 that also includes Volume I (Hydrology) and Volume III (Water Quality and LID).  We hope that these manuals allow SWMM users to gain a better understanding of the computational methods and techniques used by the program.

These volumes were completed by Dr. Lewis A. Rossman, EPA Emeritus.  In his extraordinary career, he has written three remarkable EPA public domain programs:  SWMM, the National Stormwater Calculator (https://www.epa.gov/water-research/national-stormwater-calculator which is based on SWMM),  and EPANET (https://www.epa.gov/water-research/epanet).   Since 2010, SWMM and EPANET have been downloaded at least 215,000 and 370,000 times and are the basis of many multi-billion, multi-year water infrastructure upgrades.  The codes are easy-to-use, relatively bug-free, and well-documented.  This last volume of the reference manual completes the documentation of SWMM.

Thanks, Lew, and thanks to all of you for your continued interest and support of SWMM.
