Furthermore it also prevents the sub-surface erosion caused by piping action. The following rmendations have been made on cutoff trench: 1. Y4tFGoH4ZNHG

WebA 90 m high zone-filled earth dam was constructed in a steep-walled canyon eroded by the Teton River in Idaho. It had a wide silt core, with upstream and downstream shells consisting mainly of sand, gravel, and cobbles. In the main section of the dam, the impervious core was keyed into the foundation of 30 m depth to serve as a cut-off trench.

This is essentially due to a decrease in the shear strenease in the shear stress borne by the material, or abination of the two.
