Localization of six rain harvesting and rangeland improvement projects (case study: Dehgin, Hormozgan)

The lack of sufficient and available moisture for the plant is a common problem that resulted in sensitivity of arid and semi-arid environments. In these regions, inappropriate temporal and spatial variation in rainfall is a serious issue. Thus, Showing a series a series of solutions for harvesting of the rainfall is essential. Therefore, the implementation of projects is very important. Based on the noted key matter, this study was carried out to find appropriate places for six method of the rain harvesting. In this research, first, we investigated the conditions of environmental factors(slope, rainfall, soil, vegetation) affecting on of these projects by sampling and using of the related data. Then, current and implications conditions of these factors for each of six projects were compared. Finally, the map of the appropriate places to perform these projects were produced. The results show that among of four factors affecting on implementation, just slope has a significant effect, because other factors (rainfall, soil, vegetation) had a homogeneity condition all over the region. So, the final map(map of the appropriate places to perform projects) obtained only based on the slope map. Generally, as respects to the obtained results and the regional conditions; the implementation of pitting and contour furrowing projects is only possible.
