ABSTRACT:
A method is provided for determining the depth to the saturated soil at a selected site. A first and second instance wherein the depth of the water table equals the depth to the saturated soil is identified (142). The rate of change of the depth to the saturated soil is calculated (146) as a function of the specific yield, amount of time between the instances, total precipitation occurring between the instances, and depth of the water table at each instance. Then, the depth to the saturated soil for a third instance is calculated (148) as a function of the rate of change of the depth to the saturated soil. The calculated depth to the saturated soil for a third instance may be adjusted as a function of precipitation occurring at the site.
