Summary

Internal erosion and piping in embankments and their foundations is the main cause of failures and accidents to embankment dams. For new dams, the potential for internal erosion and piping can be controlled by good design and construction of the core of the dam and provision of filters to intercept seepage through the embankment and the foundations.Internal Erosion of Dams and their Foundations brings together a selection of the best reviewed papers from the Workshop on Internal Erosion and Piping of Dams and their Foundations, held in the spring of 2005 in Aussois, France. The book covers the whole internal erosion process, from initiation of erosion, continuation, progression to form a pipe, and formation of a breach. An overview chapter based on the Workshop describes the state of the art in the field and identifies research needs. This resource will be most valuable to dam engineers, researchers and students who are involved in assessing the safety of embankment dams with regard to internal erosion and piping.
