Dupuit equation for groundwater flow
WebAn alternative formulation of the groundwater flow equation may be obtained by invoking the Dupuit assumption (or Dupuit-Forcheimer assumption), where it is assumed that heads do not vary in the vertical direction (i.e., ). A horizontal water balance is applied to a long vertical column with area extending from the aquifer base to the ...
