Subject:     How is the Volume Calculated in the SWMM 5 Groundwater Component? The  groundwater   component  of  SWMM   5  is found in the gwater.c code.  It (as is all of  SWMM   5 ) is excellently written in small functions by Lew Rossman of the EPA during the  SWMM   5  development process.  However, code being code sometimes it is easier to see how the code is functioning.  This blog or note tries to show that function.  The  groundwater   component  consists of  groundwater  data (gw in the equation) and aquifer data (a) in the equation.  The equation for the  groundwater   volume  is shown in Figure 1.   The  volume  is the water content (theta) times the upper depth and the porosity of the aquifer times the lower depth (Figure 2). Figure 1.    Groundwater   Volume  Calculations Figure 2. ...
