Dams, Dikes and Levees: Internal erosion, Overflowing and Overtopping erosion

Edito

The European Working Group on Internal Erosion (EWGIE) was set up in 1993 under the chairmanship of Andrew Charles (Building Research Establishment). 47 case histories were collected and preliminary conclusions drawn as to the features that increase the vulnerability of dams to internal erosion.

Following a number of serious incidents and failures in Europe due to internal erosion, research funding became available, with chairmanship of the EWGIE passing to Jean-Jacques Fry (EDF CIH). An inaugural workshop on definitions and research needs was held at Aussois in April 2005, with subsequent and ongoing annual workshops.
