Online workshop, Sediment Management and Institutional Stakeholders

December 14 and 15, 2020


This workshop is part of an ongoing research project on the history of knowledge and management of sediment transport in the river basins of the Po, Ebro, and Rhone, entitled Shifting Shores. The project is funded by a four-years Emergences grant from the City of Paris, Bureau de l’Innovation.


The online workshop will gather institutional stakeholders from the basins of the river Po, Rhône, and Ebro to discuss current and future challenges of sediment management in their territories. How do institutional stakeholders engage with sediment management today? What are the main challenges to be addressed? What initiatives or projects are ongoing? The goal is to better understand the current situation from the viewpoint of institutional actors and explore the possible synergies and interactions with historical and geomorphological research.


The online workshop will take place on the afternoons of Monday, December 14 and Tuesday, December 15.

On day 1, institutional managers involved in the Po, Ebro and Rhône river basins will present the state of sediment management in their basin and current and future challenges that they face in relation to it, followed by questions and comments from the participants.

On day 2, fluvial geomorphologists, historians and other researchers working on each river basin will join in three roundtables to discuss how they see history playing a role in present-day management issues, and what is the interest and value of historical data on sediment fluxes

Participation in the workshop will be limited to the speakers, and the members and collaborators of Shifting Shores project. For additional registrations, please contact

In May 2019, the SHIFTING SHORES project kicked off with an international workshop in Berkeley, California (USA) titled “The Social Life of the Sediment Balance”. This workshop has benefited from additional funding by the UC Berkeley Social Science Matrix Collaboration Grants (2018) and the France-Berkeley Fund award (2018), in collaboration with Professor G Mathias Kondolf of UC Berkeley. A selection of the workshop papers will be published as special issue of the journal Water History (Springer).
