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. Hydropower projects provide low carbon energy production, stability and reliability to the electricity grid, and water services.

Alteration in the sediment budget in the catchment, in particular, sedimentation, undermines the capacity of the hydropower projects to deliver water and energy services in addition to the upstream negative effects of delta formation and downstream scour effect.

Sediment management contributes to maintaining the storage capacity, reducing the operating risks, and minimising river connectivity impacts. Implementing effective sediment management strategies is essential to extend the life of the project, to ensure a reliable and sustainable source of water and energy, and to maintain the river connectivity.

Session objectives:

Why is sediment management important in ensuring hydropower projects deliver sustainable water and energy services?

What are the regulatory challenges, financial incentives and sector initiatives to promote sustainable sediment management?
