UK Reservoir Engineers Cited in Dam Inspection Special Feature of International Water Power & Dam Construction Publication

The Modern Dam Engineer article in the November editon of the International Water Power & Dam Construction Publication.

Like many industries, the dam industry is influenced by both internal and external factors which can prompt change. IWP&DC was interested in finding out if such elements have affected the engineer's working life when inspecting dams. We asked members of the industry for their own thoughts about the role of the modern dam engineer: Has this changed in recent years? Are engineers faced with increased challenges? And will this role continue to evolve?

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.

Reservoir Panel Engineer System Cited as Model for Fire Safety in Buildings

In the current New Civil Engineer there is an article on the Grenfell Tower incident which references the Panel Engineer system that is used to promote reservoir safety. It questions whether a similar system should be set up to reduce the risk of fire in buildings by certifying qualified risk assessors. This is positive acknowledgement of the success of our national reservoir safety legislation.
