Zoning of land Capable of Sprinkler Irrigation Using AHP Method in South- Khorasan Province

Nowadays, intense use of surface and groundwater resources, the problem of water deficiency turned into critical form, especially in agriculture. So, in case of water deficiency in agriculture, is required to use methods in order to increase the efficiency of irrigating water. One these, refers to sprinkler irrigation method. So, considering that South-Khorasan province is of the provinces located in dried and semi-dried regions and hereby, water deficiency is of the most critical problems facing farmers, this research tends to find the suitable places for sprinkler irrigation in this province. To do this, all the effective parameters in sprinkler irrigation turned into zontion using Arc GIS 9.3 software and classified with the computational average method in AHP, which in fact, was the final plan to finding the suitable place for sprinkler irrigation systems in province. According to this research, about 15% of the province bears no problem to implement sprinkler irrigation systems. About 15% have the possibility to perform such systems and 70% of the province regions have limitations to implement such systems. These limitations mostly are due to high speed of wind and chlorine amount of water resources.
