InfoSWMM and InfoSWMM SA 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 InfoSWMM and InfoSWMM SA uses to model stormwater runoff quantity … Read the rest
How to use Transects in InfoSWMM and InfoSWMM SA
Transects refer to the geometric data that describe how bottom elevation varies with horizontal distance over the cross section of a natural channel or irregular-shaped conduit. The following figure displays an example of a transect for a natural channel.
Each transect … Read the rest

Rules for using the NRCS (SCS) Dimensionless Unit Hydrograph Method in InfoSWMM and InfoSWMM SA
A unit hydrograph is defined as the direct runoff hydrograph resulting from a unit depth of excess (effective) rainfall produced by a storm of uniform intensity and specified duration. Unit hydrographs could be natural … Read the rest
Infiltration is the process of rainfall penetrating the ground surface into the soil over the pervious areas of Subcatchments.

How to Use the Clark Unit Hydrograph Method in InfoSWMM and InfoSWMM SA
Clark’s method derives a unit hydrograph by explicitly representing the processes of translation and attenuation, which are the two critical phenomena in transformation of excess rainfall to runoff hydrograph. Translation refers to the movement, without storage, of … Read the rest
