Abstract

In arid and semi-arid regions, dams are crucial for managing water resource sustainably for agriculture. Construction of dams, diversions, and urban development can alter river flow, leading to drought, reduced water supply, and environmental issues. Knowing the flow conditions and hydrological regime is crucially important. The purpose of the present research work is to evaluate the effects of dam construction on the changes in the flow regime downstream of the Hableh Rood River. In this research work, quantitative and qualitative data of the surface and groundwater of Garmsar Plain were analyzed based on the periods before and after the construction of dams, and the effects of each parameter were investigated. The results showed that after the construction of the dam, the hydrological system downstream of the dam changed including an increase in the salinity of groundwater, a decrease in the volume of river water, a drop in groundwater in the region, and the Garmsar plain, a decrease in the water level, changes in the quality of water.
