SWMM 5 - the Next Generation of EPA's Storm Water Management Model

Abstract

The U.S. Environmental Protection Agency's Water Supply and Water Resources Division is partneringwith the consulting firm ofCDM to redevelop and modernize the Storm Water Management Model (SWMM). The initial phase of this project is rewriting SWMM's computational engine using an object-based approach, providing the program with a rudimentary graphical user interface, and producing complete documentation of the program and its code. Future work will focus on improving key computational components within SWMM and enhancing SWMM's ability to model BMP and LID alternatives. The latest version of the updated SWMM can be downloaded from www.epa.gov/ ednnrmrl/swmm.
