ROSSMAN, L. A. AN OVERVIEW OF EPANET VERSION 3.0. Presented at Water Distribution System Analysis 21010, WDSA 2010, Tucson, AZ, September 12 - 15, 2010.
Impact/Purpose:
To inform the public.
Description:
EPANET is a widely used public domain software package for modeling the hydraulic and water quality behavior of water distribution systems over an extended period of time. The last major update to the code was version 2.0 released in 2000 (Rossman, 2000). Since that time there have been many useful advancements made in water distribution system modeling, many of which have been presented at past WDSA symposia. Several of these are being incorporated into an updated version of EPANET. Hydraulic modeling improvements include more efficient sparse matrix solution routines, the modeling of pressure deficient/dependent demands, more versatile options for controlling pump and valve settings, and improved stability for extended period analysis. Water quality enhancements include non-ideal mixing at pipe junctions, longitudinal dispersion within pipes, and more efficient implementation of the constituent transport procedure within pipes. In addition, several options for re-writing EPANET’s graphical user interface in a more user accessible language and platform-independent manner are being explored.
