A computer model was based initially on a previous report. Following the setting up of the physical dimensions of the model, hydrologic parameters were applied. A number of runs of the model were made incorporating changes until the model represented the steady state, non-pumping situation. Pumping was then applied to the model. Finally a model was produced showing effects of pumping at the current rate (13 800 m3/day). Following this, predictions were made at rates increased by 50, 100 and 150%. Results show that for the parameters used the pumping rate could probably be increased by 50%.
