Estimation of hydraulic characteristics of Arriyadh aquifer using BEM

The boundary element technique have been proved a valuable tool for the investigation of groundwater aquifer characteristics at unsteady state. There also some advantages of the BET over the other numerical model which enables the groundwater planing to be tested and verified quickly with a reasonable degree of accuracy. In this study, the boundary element technique is used to analyze large series of pumping test data for wells in Arriyadh city center area. The aquifer parameters have been estimated first and then used to predict the drawdowns of the wells. The computed drawdowns using the boundary element model model agreed well with the observed field data with insignificant deviation.
