| Summary: | The Green and Ampt approach was developed for the falling water table case following an initial
sudden drop in the position of the water table. The analysis presents an approximate solution for
one-dimensional flow in saturated porous media. The formulation is based on calculating the
position of draining front with time and the cumulative outflow time relationships for stratified
profile. The Green and Ampt results are checked by using data obtained from a well-proven
computer-based numerical solution for unsaturated flow equation involving an implicit finite
difference approach |
