Hydropower projects alter the sediment ﬂow in rivers by capturing the sediments in the reservoirs created by the dams, sediments including sand, gravel, and boulders are also extracted locally to meet the demand for construction materials. The combined impact of these two pressures on the river sediments can be devastating for the river ecosystems. The webinar will sensitize the participants to importance of riverbed sediments in the river ecosystems, impacts on sediment ﬂow caused by hydropower projects, extraction of sediments for commercial purposes on aquatic ecosystems, assessment of market and social aspects of sediment mining, and evaluation of supply demand balance of various grades of sediments to determine environmentally and socially sustainable extraction levels. A case study of a sediment mining plan recently prepared for a hydropower project will also be provided.
This Webinar is a ADVANCING SUSTAINABLE HYDROPOWER - Virtual Webinar Series and for more details, please see the Flyer.
About the Series
This webinar series aims to bring together different stakeholders to discuss key environmental and social issues associated with hydropower development in Pakistan. Topics were identiﬁed through a training needs assessment with participation by government agencies and private sector.
