estimate the volume of water that will infiltrate into a soil before surface saturation occurs using the Green-Ampt equation.The following data are known ;

1-saturated moisture content is 0.25
2-the initial moisture content is 0(zero)
3-the average rainfall rating is 2 in./hr
4-the average capillary suction head is 4 in.
5-K=1 in/h
What is the max. soil storage volume if the soil is homogeneous to a water table depth of 5 ft.?
