Combination of Surface and Subsurface Methods as a Suitable Method for Water Harvesting, a Case Study in the SanganeKalat Region

This research was performed for examining the potential of combining surface and subsurface water harvesting methods in a catchment. For attaining this goal، the present study was done in the Sangane watershed with an area of 600 ha. In the study area، before construction of the underground dam and the recharged dam، in spite of water crisis، a great portion of the subsurface flows and floods were lost from the country without any utilization and a great portion of livestock water for about 12000 sheep was bought at an expensive price. In the study area، water preparation for livestock purposes was performed by a combination of surface and subsurface water harvesting methods. Annually، the combining method suppliesmore than 20000 cubic meters of water with a suitable quality. The supplied water in an earthy dam not only recharges the underground dam; but it is also directly utilized for livestock usages. This research showed that in similar dry and semi-dry areas that were located in the North East of marginal locations of the country، by using this method، a great deal of suitable water for different usages can be supplied and provided.
