Cooley: USGS-- TWRI Book 6, Chapter A4. pages. 6-A5. In this study, a water balance model incorporating a two-dimensional finite element groundwater flow model of the saturated-unsaturated zone is presented. This model takes into consideration different hydrologie parameters such as rainfall, soil evaporation, crop transpiration, inter ception, infiltration, depression storage, and surface runoff. In this study, finite difference method is used to solve the equations that govern groundwater flow to obtain flow rates, flow direction and hydraulic heads through an aquifer. The aim therefore is to discuss the principles of Finite Difference Method and its applications in groundwater modelling. To achieve this, a rectangular grid is overlain an aquifer in order to obtain an exact solution. In this coupled model, surface water flow is described by the depth-averaged shallow water equations, while ground water is modeled by saturated Darcy flow. The coupling between the two models assumes continuity of pressure and water flux across the ground water/surface water interface. The coupled model is approximated by a local discontinuous.
