Impact/Purpose:
Pour Point Analysis of Land-applied Microbial Loadings and Comparison of Simulated and Gaging Station Results
Description:
This tutorial demonstrates a pour point analysis • Initiates execution of the SDMPB.• Navigates the SDMPB.• Chooses a pour point within a watershed, delineates the sub-area that contributes to that pour point, and collects data for it.• Considers land application of microbes.• Develops necessary input files to execute HSPF.• Develops necessary input file to view results from the SDMPB and HSPF.• Views simulation results for flows and microbial densities with BASINS.• Retrieves observed daily USGS flows and compares to simulated daily flows at the pour point.
