Abstract:
1. A method of determining a depth to the saturated soil in the ground at a selected site comprising: a. identifying a first instance and a second instance wherein a depth of the water table equals a depth to the saturated soil at the selected site and the second instance occurs after the first instance; b. determining the depth of the water table at the first and second instances at the selected site; c. determining a total precipitation that occurred between the first and second instances at the selected site; d. calculating a rate of change of the depth to the saturated soil as a function of e. formulating an initial equation that models the depth to the saturated soils between the time period of the first and second instance; f. using the initial equation to calculate the depth to the saturated soil for a third instance; g. measuring the depth to the saturated soil for a third instance; h. determining the difference between the calculated and measured depth to saturated soil for the third instance; i. if the difference between the calculated and measured depth to saturated soil for the third instance exceeds a predetermined amount, formulating a new equation that models the measured depth to saturated soil for the third instance.
