Assessing the surfacing of internal erosion in moraine core dams - II

Abstract [en]

In order to know the potential for internal erosion in embankment dam, a method was proposed for defining structures with a high potential for erosion. The method borrows its idea on an examination of a number of existing embankment dams with moraine cores by investigating the influence of the filter coarseness in terms of filter coarseness and the internal stability of the filter and core material. The new method furthers additional aspects like filter segregation and devoid of sufficient transition layers in order to find indicators of internal erosion prone moraine core dams.
