Investigation for Dams Civil Engineering Notes

Dams are generally classified according to its use, hydraulic design, construction design and material used in it. Geological investigation for dam site Topography: Topography in large measures dictates a first choice of dams. Generally a dam site is ideal where a valley is constricted with steep rock slopes.

Description Background. The ability to quickly and safely perform reservoir drawdown can be crucial to the protection and preservation of a dam. A reservoir low level outlet works and/or drain system with adequate capacity should be provided in all dams to provide a method of lowering the reservoir level in an emergency within a reasonable period.

Spiral Scraper. Spiral Scraper type clarifiers utilize long sweeping, curved scraper blades to move solids across a basin floor. They are similar to scraper type clarifiers in that they drag settled solids to the collection area, however, they can more quickly remove these solids and thus maintain lower sludge blankets in some applications.
