The documentation data include information about the analyst, the project, and the analysis. The site and region data include the highway-site characteristics, the ecoregions, the upstream-basin characteristics, and, if a lake analysis is selected, the lake-basin characteristics. The hydrologic data include precipitation, streamflow, and runoff ...
The lack of any comprehensive tailings dam database has prevented meaningful analysis, either gross comparisons (such as country to country comparisons, or tailings dam failures versus hydro dam failure rates) or technical failure analysis to help prevent future incidents. The records are very incomplete on crucial data elements: design height ...
The flushing flow method involves partially or completely emptying the reservoir behind a dam to erode the sediment stored on the bottom and transport it downstream. [7] [6] Flushing flows aim to restore natural water and sediment fluxes in the river downstream of the dam, however the flushing flow method is less costly compared to removing dams or constructing bypass tunnels.
An upstream tailings dam consists of trapezoidal embankments being constructed on top, but toe to crest, of another, moving the crest further upstream. This creates a relatively flat downstream side and a jagged upstream side, which is supported by tailings slurry in the impoundment. The downstream design refers to the successive raising of the ...
where m is the mass flow rate per unit area, ρ 1 and ρ 2 are the mass density of the fluid upstream and downstream of the wave, u 1 and u 2 are the fluid velocity upstream and downstream of the wave, p 1 and p 2 are the pressures in the two regions, and h 1 and h 2 are the specific (with the sense of per unit mass) enthalpies in the two regions.

Fair river sharing is a kind of a fair division problem in which the waters of a river has to be divided among countries located along the river. It differs from other fair division problems in that the resource to be divided—the water—flows in one direction—from upstream countries to downstream countries.
The downstream member in the supply chain might exploit the situation by ordering more stock than is required and returning large volumes. In this way, the downstream partner is able to offer high level of service without carrying the risks associated with large inventories. The supplier effectively finances the inventory for the downstream member.
