SWMM5 Groundwater Flow Components

Note:  There are three sub flow components in the calculation of the groundwater flow from a SWMM 5 Subcatchment. 


1st ComponentFlow = Groundwater Flow Coef. * (LowerDepth – Aquifer Bottom to Node Invert) ^ Groundwater Flow Exponent


2 nd ComponentFlow = SurfaceWater Flow Coef. * (Aquifer Bottom to Water Surface – Aquifer Bottom to Node Invert) ^ SurfaceWater Flow Exponent


3rd ComponentFlow = SurfaceWater-Groundwater Flow Coef. * (Aquifer LowerDepth * Aquifer Bottom to Node Invert)


The total flow is the sum of all three components.
