Evaluation the Effect of Watershed Dams on Underground Water Quantity (Case Study: Zoroom the Stone Mortal Dam, Hormozgan Pravinc, Chahgharbal Village, Tokahor Region)

The Artificial recharge of aquifer in order to improve and develop underground water resources is a strategy. Iran pays a lot of finance to construct the artificial recharge project. Watershed Projects are the most important activates that entails a lot of expense yearly. So evaluation the effect of these projects is essential. This investigation was performed to consider the effectiveness of Zoroom dam on the groundwater quantity in the Tokahor plain. Therefor we used water table data from two control wells and three wells trial in a 14-year- old static period(1997 – 1998 to 2010-2011) . Statics period was divided into two parts before an after the dam construction (1997-2004) to (2004-2011). Despite no change in the amount of rainfall The results indicated water table increased in test wells and decreased in control ones before and after performing this project. This shows the positive impact on the water table by performing this project in Tokahor plain.
