International Workshop on Gravel Augmentation

8th-10th November 2021, Interlaken, Switzerland

About the Workshop

The ambition of this workshop is to create and review knowledge and praxis in gravel augmentation, support the implementation of gravel augmentation measures in Switzerland and strengthen the international network among scientists and practitioners.


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 workshop, 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 bed load 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.


The workshop has a duration of 3 days. The first 2 days (8 & 9 November 2021) consist of presentations and small group discussions on specific topics. The last day (November 10) will be dedicated to field visits.

👉 A detailed program of the event will be published on this website in early 2021.

Target group and language

The workshop is conceived for people working with the issue of bedload restoration measures. Practitioners, consultants, authorities, scientists, NGOs and students are all welcome to participate. A space will be reserved for the presentation of posters.

It will be possible to participate in the different days and the excursion separately. It will also be possible to follow the part of the contributions online. However, to participate in the small group discussions the presence of the participants is necessary.

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


Early 2021 you will be able to register here.
