Abstract

Water scarcity is a worldwide problem and the best solution is to make an efficient use of water in the agricultural sector. The use of deficit irrigation is a suitable method in water scarcity conditions. In this chapter, two optimization models are explained for surface deficit irrigation to maximize the net income and application efficiency and minimize the total costs. Therefore, it developed the production function of the crops and a model for simulation of advance phase in surface irrigation. The output of these models gives us the design variables of surface irrigation. Two case studies will be presented to show the result of application of the models for a given region of Iran. These studies validate the fact that deficit irrigation is an efficient method in water scarcity conditions.
