Abstract :
Although dams are beneficial for human life by providing drinking water, irrigation and drainage, providing hydroelectric energy and economic and social development, but they also cause irreparable environmental effects on the surrounding ecosystem. Among the most destructive of these effects are changes in the level of underground water in the region, which usually falls downstream due to the obstruction of the natural flow of the river. In the present study, the situation of the groundwater level in the area of Gerdeh Bon Dam site, has been investigated as a case study. The investigation of the hydrogeological situation and the annual fluctuations of the aquifer level in two consecutive years at the Gerdeh Bon dam site, as well as the investigation of the isopotential map of the underground water level and the hydrography of the area, indicate the appropriate condition of the underground water level in the region. But it seems that due to the importance of the environmental issue, wider studies in this field and measuring all its dimensions will not be a waste of time and money.
