Workshop 3

Workshop on sediment management

Using sediment management strategies for sustainable hydropower projects

Monday 13 May 2019 | 13:00-17:30 | room: Mansart 1

Reservoir and run-of-river hydropower projects provide low carbon energy production and stability and reliability to the electricity grid with an increasing share of intermittent renewable energy sources.

Sedimentation or sediment related issues undermine the capacity of hydropower projects to deliver these water and energy services and weaken therefore the path to accomplish SDG 6 and SDG 7.

Sediment management contributes to maintaining storage capacity, reducing operating risks, and minimising river connectivity impacts. Managing sediment 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.

This workshop will focus on the impacts of sedimentation and available sediment management techniques, and will provide guidance on tools to determine an effective strategy that contributes to sustainable reservoir operation. It will also demonstrate how numerical and physical scale models can support the design of sediment management measures.

Workshop objectives:

The workshop aims to present international good practices on effective sediment management to contribute to the sustainable operation of hydropower assets.

In this workshop, the audience will be trained in the RESCON 2 tool for a rapid assessment of sediment management strategies as well as the capabilities of numerical and physical modeling to support detailed sediment management studies.

Case studies will offer examples of how effective sediment management alternatives contribute to sustainable operations of hydropower assets.
