Estimation of groundwater variations in an anisotropic leaky aquifer: A ditch drain model

Abstract

This paper deals with the development of mathematical models for water table fluctuation in 2-D anisotropic aquifer. Time dependent recharge and withdrawal are taken into consideration. A Boussineq equation - nonlinear partial differential equation governs the flow. The PDE is solved using finite Fourier sine transforms and closed from expression are obtained. The sensitivity of the parameters is tested using hypothetical data. Effect of leaky nature of aquifer base on the water table has been analyzed.
