Abstract

The different parameters such as water, soil and climate have an important effect in the decision making and performance of pressurized irrigation systems. The underground and surface water resources in per region have no unique quality and quantity. The Kerman Plain, which has about 7500 km2, is located in the Kerman Province. The irrigation of this plain is done with using the underground water resources which are facing drop in the water level, due to over exploitation. Accordingly, the pressurized irrigation is suggested in order to the prevention of drop the loss trend and increasing irrigation efficiency. The aim of this research is to identify suitable lands for performance of pressurized irrigation system, with the help of remote sensing techniques and geography information system (GIS), in Kerman plain of southeast of Iran. In this research, 2 methods of site selection: logical overlay method –Boolean method- and Arithmetic overlay - proportion percent method are compared and evaluated. On the basis of Boolean site selection model 5% of desert lands for performance of sprinkle irrigation and 25% of lands for drip irrigation and on the basis of arithmetic overlay 15% of lands for performance of sprinkle irrigation and 20% of them for performance of drip irrigation reasonably were recognized. The comparison of these 2 methods with considering the condition of regions showed that arithmetic overlay site selection model is more suitable for recognizing the suitable zones for performance of pressurized irrigation systems.
