Emphasis is placed on easily measured parameters and field-measured data.
The maximum soil-profile water storage and the maximum groundwater level resulting from the recharge event exhibit the lowest coefficients of variation, whereas the amount of recharge exhibits the highest coefficient of variation. The yearly recharge in the Great Bend Prairie ranged from 0 to 177 mm with a mean of 56 mm. Most of the recharge events occur during the months of April, May, and June, which coincide with the months of highest precipitation in the region. A multiple regression analysis revealed that the most influential variables affecting recharge are, in order of decreasing importance, total annual precipitation, average maximum soil-profile water storage during the spring months, average shallowest depth to water table during the same period, and spring time rainfall rate. This recharge zonation is in excellent agreement with the field-site recharge values.
