EROSION AND SEDIMENTATION

The Hydropower Erosion and Sedimentation How-to Guide provides an overview of current knowledge and effective practices from across the sector in managing risks associated with erosion and sedimentation. The publication will help hydropower developers and operators manage potential impacts arising from erosion and sedimentation in a river basin, allowing decision-makers to avoid business risks and act responsibly towards the environment and local communities.

The guide covers potential impacts upstream and downstream of a hydropower project, sediment transport in rivers, erosion from the project site, civil and electromechanical structures, and climate change. It presents methodologies and technologies related to scoping and siting, design and mitigation, and assessment and monitoring. The guide in addition highlights how such measures can increase a project’s resilience to hydrological variability and support climate change adaptation.
