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
