Abstract:
Groundwater models provide a scientific and predictive tool for determining appropriate solutions to water allocation,
surface water-groundwater interaction, landscape management or impact of new development scenarios. However, if
the modelling studies are not well designed from the outset, or the model does not 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 the common pitfalls and sensitivities which are
normally encountered during groundwater modelling studies. It will help in improving the model conceptualisation
and understanding the uncertainty in model results.
