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
2.5 Decomposing the Corrected Flow Data
The corrected flow data can be decomposed into its DWF, GWI, and RDII flow components with the help of the rainfall data. The decomposition process is illustrated in this section.
Determining the DWF Component
The first step towards determining the DWF component of the … Read the rest
InfoSWMM and InfoSWMM SA offer 13 choices for modeling surface runoff (click on link to see more information on each method):
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
