WebAn embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi- plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. [1]
