Message from the BDS Chair

Welcome to the September BDS eNewsletter.

New research kicks off on the performance of dams under overtopping

There is a recognition of the need to better understand performance of both flood defence and reservoir embankments in resisting erosion under overtopping. In the UK, it is planned in due course to carry out a comprehensive five year research project to include field trials to assess erodibility of grass and soil. This coincides with ICOLD setting up a technical committee on Levees, set up to build upon ongoing collaboration between similar existing committees in the US and Europe. EURCOLD is holding an International Workshop on Embankment and Concrete Dams Overflowing Erosion in France in December, with a number of representatives from the UK attending.
