Field experiments were conducted during the summers of 1994 and 1995 to test feedback-controlled surge irrigation strategies. Feedback-controlled surge irrigation proved promising for better water management in a field with large lateral variations in infiltration rates. It was shown that feedback-controlled surge irrigation resulted in nearly equal effective depths on both sides of the surge valve and high application efficiencies. Predictions of advance inflow time, runoff ratio, and soil water content were compared with field measured values. Modeled predictions were acceptable for practical application.
