The creation of river dams and the storage of water have been a strategy for survival for many centuries. Reservoirs have diverse functions, providing irrigation, water supply, storage of water, flood control, navigation and power generation. The silting of a reservoir is an unavoidable process. Although it cannot be halted, silting can be slowed …

Like many other dams, Imperial Dam impounds much of the suspended sediment moving in the Colorado River but some of that suspended sediment makes its way to the All-American Canal, a major diversion for irrigation and municipal water. Water entering the All-American Canal is settled in several desilting basins to remove most of …
The All-American Canal Desilting Works in southwestern United States is of this type. Water is diverted from the Colorado River and routed directly to the desilting installation from which the clear water is then routed to the canal. The diversion into the All-American Canal is about 345 m 3 /s, which carries a sediment load of 90,000 ton/day ...

The paper presents the methodology of dredging and the use of a sorting and distributing device that sorts, distributes, and stacks larger particles of the solid phase of the slurry in the side prisms and smaller particles and screening in the middle part of the backfill dams or dumps. These are the final link in the technological chain of dredging operations.
