Unsteady state drainage in a vertically heterogeneous soil

An analytical model is presented for prediction of transient water table heights between two parallel drains for a vertically heterogeneous soil. The drains lie on a horizontal impervious layer. The model was applied to field conditions for prediction of water table fluctuations in a clay soil whose...

Description
Summary:An analytical model is presented for prediction of transient water table heights between two parallel drains for a vertically heterogeneous soil. The drains lie on a horizontal impervious layer. The model was applied to field conditions for prediction of water table fluctuations in a clay soil whose hydraulic conductivity decreased exponentially with depth. The predicted results compared reasonably correctly with field observations for a given long-term rainfall input.
