75th anniversary of the Swiss Dams Committee
This retrospective was conceived as part of the 75th anniversary of the Swiss Committee on Dams (SCD). It retraces the history of dams in Switzerland through five specific themes: the players, the flagship dams, the socio-political dimensions, the technical dimensions and the impact of Swiss dam engineering abroad
This timeline was drawn up by the members of the SCD "Public Relations" working group, headed by Jean-Claude Kolly.
