Furrow Infiltration Under Surge Flow Irrigation

ABSTRACT Aflowing furrow infiltrometer was used to investigate the infiltration behavior of three soils for continuous flow and three different surge flow conditions. With each of these surge treatments, the quasi-steady infiltration rate was reduced significantly below that measured for continuous flow conditions. The greatest reductions were observed on a fine sandy lom soil. A rebound effect was evident with the surge treatments, where the initial infiltration rate following the off-time was higher than the infiltration rate measured at the end of the preceding surge.
