Using GIS for Optimization the Irrigation Program From Repository Dams
Author(s):
Abstract:
Due to the water shortage and drought that have occurred in recent years in our country, the planning for the optimal management of water use in different applications is necessary. The agricultural sector is the largest consumer of water and yet most of the water loss is also related to it. As it is said, about 60% of drinking water is wasted in agriculture.
Since irrigation is primarily a matter of spatial case, and is related to the location information such as the location and position of land, location of transmission canals and etc., so capabilities of spatial information systems (GIS) could be used for better and more successful planning.
In this paper, using optimization capabilities in GIS, program of irrigation of reservoir dams have been set, so that the farmer’s water need to be covered and the amount of waste water to be at least. For this purpose, the path of the water motion in the canals is minimized and the irrigation of farms that are under one canal be done simultaneously. If not enough water in the reservoir, Method of determining the optimum cropping pattern using the AHP method are provided. The method presented in this paper has been implemented and evaluated in a case study in Golestan dam irrigation network.
