Ground-Water Recharge Simulation

Formulation and solution of a two-dimensional nonlinear computational model based on potential theory pertaining to a typical ground-water recharge pattern are presented. The objective of the present study is to direct attention toward an evaluation of this theoretical model by comparing it with the corresponding linear and nonlinear models based on Dupuit-Forchheimer approximations for the unsteady hydrodynamic behavior of the proposed recharge system under saturated flow conditions. Superiority in regard to generality of its application as well as accuracy of the results obtained is demonstrated by comparing it with the pertinent experimental data and presented in the form of dimensionless graphs.
