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.
Life cycle engineering is defined in the CIRP Encyclopedia of Production Engineering as: "the engineering activities which include the application of technological and scientific principles to manufacturing products with the goal of protecting the environment, conserving resources, encouraging economic progress, keeping in mind social concerns, and the need for sustainability, while optimizing ...
The first stage, which incorporates the feedstock or fuel production and processing and fuel delivery or energy transmission, and is called the "upstream" stage, while the stage that deals with vehicle operation itself is sometimes called the "downstream" stage. The well-to-wheel analysis is commonly used to assess total energy consumption, or ...
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 ...
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 ...
Vertical integration is the degree to which a firm owns its upstream suppliers and its downstream buyers. The differences depend on where the firm is placed in the order of the supply chain. There are three varieties of vertical integration: backward (upstream) vertical integration, forward (downstream) vertical integration, and balanced (both ...
The dam was originally proposed to be built at the Laiban Dam site in Tanay, Rizal, but was later disapproved because a dam in Tanay would submerge a larger area. The site downstream in Quezon Province was approved instead, with the areas in Tanay and Teresa becoming sites for the upstream reservoir and conveyance tunnels instead. [8]
Downstream of the Kishanganga dam, the river is taking a U-turn to enter Pakistan territory. Nearly 20 million cubic meters capacity gross storage dam can be envisaged close to the LoC to impound all the inflows which can be further pumped through a 6 km long tunnel into the upstream Kishenganga dam reservoir. The augmented water into the ...
