Focus Session

Sediment management

Managing sediment in the context of climate change and integrated river basin development

Wednesday 15 May 2019 | 15:45-17:00

Hydropower has a prominent role in achieving the Paris Agreement. Reservoir and run-of-river hydropower projects provide low carbon energy production, stability and reliability to the electricity grid, and water services. Sediment transport changes in the basin may undermine the capacity of hydropower projects to deliver water and energy services in addition to the upstream adverse effects of delta formation and downstream scour. Sediment management contributes to maintaining storage capacity, reducing operating risks, and minimising river connectivity impacts. Implementing effective sediment management strategies is essential to extend the life of a project, to ensure a reliable and sustainable source of water and energy, and to maintain river connectivity.

Session objectives:

Why is sediment management important so hydropower projects deliver sustainable water and energy services? What are the regulatory challenges, financial incentives and initiatives to promote sustainable sediment management? This session will discuss the importance of managing sediment in reservoir and run-of-river hydropower projects. Current and future projects are essential to deliver effective water and energy services in a context of increasing demands exacerbated by climate change.
