Storm Water Management Model Reference Manual Volume II – Hydraulics

Citation:

Rossman, L. Storm Water Management Model Reference Manual Volume II – Hydraulics. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-17/111, 2017.

Impact/Purpose:

This document provides the underlying mathematics for the hydraulic calculations of the Storm Water Management Model (SWMM). These manuals are intended for users of the SWMM and complement the SWMM 5 User’s Manual (US EPA, 2010), which explains how to run the program, and the SWMM 5 Applications Manual (US EPA, 2009) which presents a number of worked-out examples.

Description:

SWMM is a dynamic rainfall-runoff simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of subcatchment areas that receive precipitation and generate runoff and pollutant loads. The routing portion of SWMM transports this runoff through a system of pipes, channels, storage/treatment devices, pumps, and regulators. SWMM tracks the quantity and quality of runoff generated within each subcatchment, and the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period comprised of multiple time steps. The reference manual for this edition of SWMM is comprised of three volumes. Volume I describes SWMM’s hydrologic models, Volume II its hydraulic models, and Volume III its water quality and low impact development models.
