2 Design of Components of Earthfill Dam 1. Top Width of Earthfill Dam The top width or crest width of dam should be sufficient to withstand seismic forces and wave action. The seepage line should be within the dam width when the reservoir is full. The top width of a dam is decided based on the height of dam.

  • How To Build An Earthen Pond And Dam Wall Peak

    The dam wall is up and compacted now it is time to shape the bowl. It is important that you have no steeper than a 3 to 1 grade on the inside of the dam wall. The shore line can be 2 to 1 but I would not recommend anything steeper than 3 to 1 as it makes it difficult to compact unless you use a compactor attached to an excavator arm.
