The Use of Multiple Linear Regression in Simulating Ground‐Water Level Responses

The simulation of water table responses is discussed and the use of multiple linear regression as a modelling technique is considered. It is calibrated and validated against actual field data from the Vryburg aquifer in South Africa. The model permits the consideration of changes in properties of recharge, discharge and aquifer parameters simultaneously. By use of such a model, water table responses in the Vryburg area can be simulated six years ahead of time, using rainfall and discharge through pumping as the only input parameters. This technique can be regarded as a rapid, first approximation and low‐cost procedure which is unsurpassed as far as time and costs are concerned.
