This document verifies that groundwater flow principles are correctly implemented in PLAXIS. The purpose of this example is to determine the length of the seepage face l in an inclined river bank with slope a . The problem geometry is presented below. Assuming a point P on the phreatic surface, with known location determined by length L and height H, the seepage face l and the phreatic surface are found through a set of nonlinear equations.
This requires a PlaxFlow module for groundwater flow
