Mar 24, 2025 · EPA's Storm Water Management Model (SWMM) is used throughout the world for planning, analysis and design related to stormwater runoff, combined and sanitary sewers, and other drainage systems in urban areas.
Our stormwater manuals provide stormwater permit implementation and management guidance. Contact your municipality or permit administrator to determine which manual you need and for questions regarding implementation ...
Aug 7, 2023 · EPA's Storm Water Management Model (SWMM) is used throughout the world for planning, analysis and design related to stormwater runoff, combined and sanitary sewers, and other drainage systems in 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 pi...
SWMM is a dynamic hydrology-hydraulic water quality simulation model. It is used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas.
Storm Water Management Model (SWMM) Urban planners and landscape designers use this downloadable program to simulate the quality and quantity of rainfall over urban and suburban areas.
