Channel/pipes were identified by type, <br />flow section geometry, length, slope, and Manning's <br />roughness coefficient as specified in Section 4 of the <br />SWMM manual. Subcatchments were identified for the <br />appropriate inlet locations. Discretization of the <br />various subcatchment areas followed procedures outlined <br />in Section 4 of the SWMM manual. <br />v 13 <br />
