Multiperiod linear programming in irrigation allocation

Abstract

An irrigation allocation model using multiperiod linear programming was developed to allocate canal irrigation water among different irrigated fields in order to maximize net benefit for given conditions. These conditions include irrigation water demands for each field, crop response functions, water supply quantities, canal carrying capacity, water cost, crop values and minimum irrigation limitations for surface irrigation systems. The model was validated using the soils, crops, canal description and management data of the Maricopa Agricultural Center (MAC), University of Arizona. Test results demonstrated allocation model applicability at MAC.
