The development and application of a digital computer model of the ground water reservoir of the island of Anholt is described.
The model is based on a finite difference, two-dimensional approach. It was successfully used to investigate if the ground water at a planned well field might be polluted by sewage from nearby cesspools. Although the model is an approximation of the real aquifer conditions, the authors found the model very useful and suggest that modelling techniques be more widely used in ground water resource investigations.
2D models based on the shallow water equations are widely used in river hydraulics. However, these models can present deficiencies in those cases in which their intrinsic hypotheses are not fulfilled. One of these cases is in the presence of weirs. In this work we present an experimental dataset including 194 experiments in nine different weirs. The experimental data are compared to the numerical results obtained with a 2D shallow water model in order to quantify the discrepancies that exist due to the non-fulfillment of the hydrostatic pressure hypotheses. The experimental dataset presented can be used for the validation of other modelling approaches.
