Abstract
Water resources are increasingly scarce and depleted owing to the effects of local socio-economic development. Hydropower development changes the hydrological regime and the amount of alluvium downstream through the process of reservoir regulation and operation. To evaluate the potential of reservoir effect on river basin flow, we performed a flow assessment in the presence of structures and compared it with control case in which there are no reservoirs. In the Srepok river basin with many hydroelectric power plants built on terraces on rivers. Due to the dense construction surrounding the river, the flow has changed and there have been incidents of hydropower causing damage to crops and households. The results show that, in general, due to the influence of hydroelectric reservoirs, the annual flow is not significantly reduced and the amount of alluvium tends to increase. This research was conducted to provide comprehensive information on hydropower development, and at the same time provide a reliable source of information to help managers make timely and accurate decisions.
