When ground water flows from an unconfined aquifer to a surface reservoir the position of the water table will change with time. The nonlinear partial differential equation for water table elevation is transformed to a nonlinear ordinary differential equation by similarity substitution and a numerical procedure for its solution is presented. A method of computing bank storage is presented. The solution compares favorably with the experimental results obtained by others.
