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.
Live Chat2 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.

This is mainly due to insufficient compaction of soil used for the dam faulty construction of dam shrinkage cracks animal burrows in dam body etc. This problem will arise mostly near the pipe conduits passing through dam body.
Live ChatDam construction must be started when river levels are low. A small dam called a cofferdam is built upstream of the construction one to help funnel water into the diversion tunnel. A cofferdam may be built downstream as well but the overall goal is to keep the construction one dry so that the main dam
