Abstract
In general, the protection and utilization of surface water in arid regions, done by different methods such as Flood water spreading that undoubtedly will affect on sustainable development of groundwater resources. In order to provide, suitable, executive and manageable solution, Continuous monitoring is essential for such projects. For this reason the effect of Dehender Flood spreading on downstream unconfined aquifer was evaluated. For this purpose, the location of flood spreading and hydrogeological conditions of downstream aquifer determined by data and information that are Gathered from Hormozgan regional water authority along with field observations. Then 7 Observation wells were chosen. Finally, the effect of flood water spreading on water table surface groundwater changes was investigated by using underground water balance equation and unit hydrograph befor and after the construction of flood spreading system. The results of this evaluation showed that the average level of the water from sea level at the central of the plain(are not affected by flood water spreading) and near flood spreading (are affected by flood water spreading respectively) befor and after the construction of flood spreading system are: 213.4 ,209.5 and 254 ,251 meter of the sea level. As a result we can state that flood water spreading play an important role in sustainable development of ground water resources.
