Notes on Dupuit Equation for Steady-State Flow to a Trench in an Unconfined Aquifer (No Recharge)
  • Select the required output, then set the other parameters to the required values.
  • The Dupuit equation for horizontal flow can also be applied to flow to a river, but caution should be used when interpreting results as riverbed permeabilities can vary significantly from the surrounding aquifer material.
  • The Dupuit equation for horizontal flow only applies if the water table in the aquifer and trench is constant.
