Abstract

The theory of non-stationary flow has, been applied to the movement of water in the upper layers of the Pleistocene terrace on the western side of the river IJssel. A Fourier analysis of the movement of the water levels in the river and in several wells permitted calculation of the ratio of permeability to the storage coefficient of the soil. Assuming that the storage coefficient was o. I0 and the average thickness of the aquifer was I5 m, the average permeability was calculated to be 53 m/day. The discharge of water from the soil (0.8 cu m/day) can be calculated without knowing the thickness of the aquifer. The method can be used to calculate the amount of water needed for irrigation and the amount of water percolating from the hinterland to the river.
