Classification of Management Alternatives to Combat Reservoir Sedimentation

Abstract: Sedimentation is steadily depleting reservoir capacity worldwide, threatening the reliability of water supplies, flood control, hydropower energy and other benefits that form the basis of today’s water-intensive society. The strategies available to combat reservoir sedimentation may be classed into four broad categories. Three proactive categories seek to improve the sediment balance across reservoirs by: (a) reducing sediment yield from the watershed, (b) routing sediment-laden flows around or through the sto… Show more

“…A first attempt to avoid the effect of sedimentation on the reservoir operation started in 2015 by retarding the delta advance towards gradually raising the reservoir's minimum operating level. Several adaptive strategies have been reported to mitigate and prevent sedimentation impacts [23]. In this regard, the minimum level rose to 1210 m, being continuously increased at a rate of 0.5 m per year and focusing new deposits onto the top of the delta.…”

“…The fulfillment of such SDG requires changes such as new management schemes and more presence of renewable energy projects in the mix [2]. Within such renewables, and despite some of their drawbacks [3][4][5][6], hydropower projects represent valuable assets for the electric power sector, since they provide an important support for grid and mix planning within several countries [7][8][9][10], especially in developing countries in which population is growing faster [11]. According to the International Energy Agency [12], cost reductions for renewables and advances in digital technologies are opening opportunities for energy transitions, which implies that policy makers need to move fast to keep up with the pace of technological change, allowing the appearance of flexible power systems.…”

“…The global extent of natural wetlands declined by 30% between 197030% between and 200830% between (UNEP, 2015. Overall, the growth of built-up areas causes the cities in downstream to expose to floods six to eightfold higher than it would have been under the natural land cover (Morris, 2020). In cities the built-up areas cover the land with impermeable surfaces such as roads, buildings, pavements that affect the natural flood defence mechanisms, particularly, infiltration and surface runoff.…”
