Dupuit’s assumption — A simplifying assumption for the solution of a free surface well flow problem [16] (e.g. a water table aquifer.) It is based on the assumption that the slope of the phreatic surface is negligibly small so that the equipotential lines are… … Lexicon of Cave and Karst Terminology
Dupuit assumption — The Dupuit assumption holds that groundwater moves horizontally in an unconfined aquifer, and that the groundwater discharge is proportional to the saturated aquifer thickness. It was first designed by Jules Dupuit in 1863 to simplify the… … Wikipedia
