Two field tests were conducted to study the effect of cycling furrow inflows on advance rates. Earlier investigations had demonstrated the concept and termed it surge flow irrigation based on the hydraulic behavior of the cycled, or pulsed, inflow along the furrow. Surge flow treatments were compared with continuous flow tests having the same time-averaged flow rate. All of the tests indicated that surge flow produced significantly faster advance rates. The primary affects were noted during the water application to newly formed furrows with lesser differences in subsequent irrigations. Temporal and spatial variations in furrow intake rates were substantially reduced by the surge flow practices indicating a major advantage of the technique.
