Numerical modelling of ground water flow using MODFLOW

Abstract

Ground water models provide a scientific and predictive tool for determining appropriate solutions to water allocation, surface water – ground water interaction, landscape management or impact of new development scenarios. However, if the modelling studies are not well designed from the outset, or the model doesn’t adequately represent the natural system being modelled, the modelling effort may be largely wasted, or decisions may be based on flawed model results, and long term adverse consequences may result. This paper presents an overview of the ground water modelling technique and application of MODFLOW, a modular three-dimensional ground water flow model.
