Runoff Coefficients for InfoSWMM, InfoSWMM SA, ICM and XPSWMM

Runoff Coefficients

Runoff coefficient is loosely defined as the ratio of runoff to rainfall, and is a function of watershed characteristics including land use, soil type, and slope of the watershed. The value of runoff coefficient ranges between 0.0 and 1.0. A value of 0.0 means that all of the … Read the rest

Example 5. Runoff Water Quality for #SWMM5 and #InfoSWMM from the EPA Applications Manual

Example 5. Runoff Water Quality

This example demonstrates how to simulate pollutant buildup and washoff in an urban catchment. The influence of different land uses on pollutant buildup is considered and both Event Mean Concentrations (EMCs) and exponential functions are used to represent the washoff process.

Surface runoff quality is … Read the rest
