Abstract:
Groundwater flow modelling studies are required to resolve groundwater and catchment
issues. A model, no matter how sophisticated, will never describe the groundwater system
under investigation without deviation of model simulations from the actual physical processes.
As a consequence, in applying a numerical model to a field study, the model user should
always understand the implications of simplifying assumpti'ons. This paper addresses
groundwater modelling concepts and outlines the approach for commissioning and
understanding groundwater modelling studies. It will encourage best practice and help avoid
potential problems.
