Witryna6 lis 2024 · The roughness coefficient reflects the amount of resistance that overland flow encounters as it runs off of the Subcatchment surface. Since InfoSWMM uses the Manning equation to compute the overland flow rate, this coefficient is the same as Manning’s roughness coefficient n. WitrynaA note on the V-Notch weir coefficient with SWMM: In Bentley StormCAD the weir coefficient (Cv) is Unitless and has a typical value around 0.58. However, in SWMM the v-notch weir coefficient (C) is unitized. In order to account for this the unitless value is converted to the unitized value upon export using the following equation. Witryna13 lis 2024 · SWMM5 uses a general equation to represent under drain flow to provide flexibility to use different hydraulic conditions: where, q = drain flow (in/hr mm/hr} C … txr 2516
