Description
Summary:A numerical procedure is presented to deal with recharging and dewatering of unconfined homogeneous aquifer. The new procedure, referred to as the Green element method (GEM), relies on the singular integral theory of the boundary element method (BEM) and permits the solution integral replication of the governing non-linear partial differential equation by domain discretisation. Hence, the advantages of both BEM and the finite element method (FEM) are utilised. Numerical results from test problems obtained by GEM are compared with those from the literature, and for all cases, the results were found to be very encouraging.
