Gravel augmentation measure at the Limmat river (2019). Carlos R. Wyss.

The ambition of this symposium is to create and review knowledge and praxis in bedload management, support the implementation of restoration measures in Switzerland and strengthen the international network among scientists and practitioners. The symposium will be held on-site if possible, and we will also provide live-streaming of the presentations.


Switzerland has the legal goal and the financial tools to restore its rivers from the impacts of sediment deficits created by hundreds of hydropower plants, retention basins and other installations. This goal is challenging in practical and scientific aspects. Gravel augmentation measures are put into practice to improve the ecologic and morphologic state of the rivers. However, the dimensioning and implementation of these measures depend on the target state and the driving physical and ecological parameters for which there is little understanding today.

With this symposium, we aim to support the practical implementation of gravel augmentation measures in Switzerland through the presentation of case studies and the latest tools, techniques and strategies to improve bedload transport and its ecological functions. Experts in the field, whether they are scientists or practitioners, have the opportunity to learn from experiences of a remarkably active and pioneering restoration setting in Switzerland.

Target group and language 🇬🇧🇩🇪🇫🇷

The symposium is intended for people working with the issue of bedload restoration and management. Practitioners, consultants, authorities, scientists, NGOs and students are all welcome to participate.

The presentations will be made in French, German or English and will be simultaneously translated.
