Conclusions
-
1.
As indicated in the project design, it is possible to erect dams without coffer dams, excavation, and dewatering, i.e., without excavating the river bed alluvium on mountain streams, similar to the Atbashi River. The watertight structures in the submerged section of the dam can be made by cementation of the alluvium and core of the dam.

2.
When the stream has a large silt burden, which will rapidly silt a canyon reservoir, it can be used as a settling pond with periodic annual deep flushing. The system of operating the reservoir which has been adopted eliminates the necessity for constructing the ordinary type of settling ponds, which is impossible or very difficult in canyon stream beds.
