A new IHA guide 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 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.

It 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.

The guide 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.

IHA Sustainability Specialist, Alain Kilajian, said: “Effective erosion and sediment management is essential to sustainably develop and operate a hydropower project. This guide looks at good practices in the field and provides hydropower professionals with practical approaches to managing even the most challenging issues.”

Lead author and independent environmental and social consultant, Doug Smith, said: “Effective management of erosion and sedimentation is fundamental to hydropower’s role in a low carbon future. With its catalogue of methodologies and technologies, I hope the guide provides clarity on how to do this, where to begin, and where to find further advice and expertise.”
