Abstract

Population growth over the last decades and consequently the need for food, have led humans to dominate more cultivated land. Inevitably, these lands require water, which can be possible by controlling the rivers water by constructing dams. Finding suitable land for agricultural purposes in a way that suitable conditions for cultivation and also water required for it can be provided by various methods such as controlling surface water (dam) and underground water (well drilling, etc.) It has always been the attention of experts. In this study, the feasibility of suitable agricultural lands in the upstream of the Javeh dam has been investigated. Accordingly, by assuming pumping water with different heads from the pumping station in the dam reservoir, taking into account different factors (slope, head, distance and land use), the site selection has been carried out. Spatial analysis was performed using ArcGIS software. By overlapping the factor maps and weighting each one of them, the appropriate ranges are derived based on the defined factors. The results show that by increasing the head twofold, the area of the selected range is almost doubled, while by increasing the head fourfold , the area of the selected range increases about six times. It should be noted that in this study, verification of the selected areas has done by using satellite images.
