Aquifers in SWMM 5

Subject:   Aquifers in SWMM 5

 Groundwater in SWMM 5 is modeled as two zones: (1) Saturated and (2) Unstaturated.  The data for the Groundwater Simulation consists of physical data in an Aquifer and elevation and flow coefficient and exponent data in the Groundwater Data.  The Aquifer data object can be applied to multiple Subcatchments but each Subcatchment has its own set of Groundwater data.  For example, in this model all of the Subcatchments share the same Aquifer data but each Subcatchment has different elevation and flow data – the labels on the basin are the groundwater elevations.
