Dupuit equation for groundwater flow
Web2.3.7.3.2.2 Confined groundwater. m symbolizes the pressure head measured in the middle of the confined thickness He, instead of the aquifer’s roof, the total head corresponds to (B + Hc/2+ Pm)/ pg. By Dupuit’s assumption, 2H/5z = 0, then P m= Hc/2 + P. However, one must keep in mind that Dupuit’s simplified modeling for some situations ... WebAnalysis of the flow line in Figure 1 shows that the water flow has diffluent rates in the horizontal and vertical directions and belongs to the plane two-dimensional flow. If the Dupuit assumption can be introduced and the vertical diffluent rate is neglected, the calculation can be simplified to a one-dimensional flow calculation in the x ...
