Objectives
In planning this study the purpose was to determine the rate of horizontal advance of irrigation water as related to the infiltration characteristics of soils. The specific objectives were ; (l) to design and operate an irrigation model in which the horizontal advance of water on the surface was to be determined for different porous mediums with different infiltration characteristics, and for different conditions of surface slope and roughness, (-2). to compare mathematical solutions with model data, (3) to use dimensionless functions to represent the model data, and (4) to use field determined infiltration equations to develop theoretical curves for the horizontal advance of flooding irrigation water under field conditions. The theoretical curves are for different soil types, for different antecedent moisture content, and for different depths of surface storage.
