Computational Method

GeoSWMM is a physically based, discrete-time simulation model. It employs principles of conservation of mass, energy and momentum wherever appropriate. This section briefly describes the methods GeoSWMM uses to model Stormwater runoff quantity and quality through the following physical processes:

·       Surface Runoff

·       Infiltration

·       Groundwater

·       Snowmelt

·       Flow Routing

·       Surface Ponding

·       Water Quality Routing
