Abstract: This paper describes a means for estimating canal seepage contribution to nearby agricultural subsurface drains. Canal seepage rate is influenced by a complex of many variables, but the rate is predominated by the soil properties at and near the flow boundary of the canal. The procedure for estimating canal seepage examines a seepage loss factor at the canal flow boundary, as feet per square feet per day, in respect to a soil factor that utilizes the precentage of fines, defined as the 0. 074 millimeter size, and the slope of the sand fraction.
