Hydropower projects can have significant impacts on erosion and sedimentation processes in watersheds. However, with careful planning and management, these impacts can be avoided, minimised and mitigated. This post outlines various strategies to manage erosion and sedimentation related to hydropower projects, aligned with best practices such as the Hydropower Sustainability Standard.

Effective planning and operation of hydropower projects necessitate understanding and monitoring erosion and sedimentation. Key considerations during the preparation stage include hydrological data analysis, instream sediment monitoring, climate change predictions, impacts of surrounding reservoirs, and an assessment of the catchment condition. The integrity of the project’s slope stability and erosion risks, alongside robust sediment sampling…
