Abstract:

The recharge and discharge parameters that determine the fluctuation of water-table of a shallow unconfined aquifer due to rainfall, evapotranspiration, tube-well and canal supplies are obtained using the recursive least squares method. The parameters are predicted by minimizing the mean square error between the estimated and measured water-table levels. Water-table fluctuations are shown to be dependent upon pumping rates and prior rainfall, and can be simulated by a multiple linear regression model. Such models can be used for forecasting and controlling of the ground water tables and once formulated are ideally suited to the management of ground-water systems where more costly and complex methods cannot be used.
