RESERVOIR SEDIMENTATION: CAUSES, EFFECTS AND MITIGATION …
2019年10月1日 · Reservoir sedimentation therefore is filling of the reservoir behind a dam with sediment carried into the reservoir by streams. This paper therefore describes sedimentation processes,...
A review of sedimentation rates in freshwater reservoirs: recent ...
Sediment deposition in water reservoirs has major implications for storage capacity, reservoir lifetime, and water quality. Changes in rainfall patterns and land use will consequently alter the rate of erosion and therefore have a direct effect on sedimentation rates.
Reservoir Sedimentation and Its Control | Water Engineering
The reservoir sedimentation can be controlled by selecting such a site for the reservoir where the sediment inflow is low. Thus if alternative sites for a reservoir are available then a site which excludes runoff from an easily erodible part of the catchment area should be preferred to the one which includes this runoff.
Sustainable sediment management in reservoirs and regulated …
2014年4月4日 · We begin describing methods in the first two categories (that pass sediment through or around the reservoir, minimizing sediment accumulation in the reservoir and supplying some sediment to downstream reaches), then address strategies to reduce sediment supply from the upstream catchment (which do not address downstream sediment starvation ...
盆地结构控制下的地层压力-流体-储集性协同演化及控藏作用—— …
东营凹陷成藏动力学过程及油气藏原始状态相对完整，基于古近系地层压力场、流体场、储集物性现今特征及其演化过程研究，建立了东营凹陷地层压力-流体-储集性协同演化模式，明确了其控藏作用。 在构造活动、沉积作用的控制下，东营凹陷地层压力经历了"升高—降低—升高"的演化过程，成岩流体性质表现为"酸、碱交替"，沉积组构和成岩流体作用控制形成了不同成因类型的有效储层。 在断陷盆地结构控制下，东营凹陷陡坡带发育"常压/弱超压—碱/酸—中/低孔（少量高 …
Reservoir Sedimentation - SpringerLink
Reservoir sedimentation is a process that involves the gradual accumulation of incoming sediment within a reservoir. The process is a result of a complex interaction between the various sediment transport processes that prevail in the river and the surface soil erosion within the basin as well as the hydrodynamics of the reservoir.
Sedimentation reduces reservoir storage capacity for flow regulation and with it all water supply and flood control benefits, plus hydropower, navigation, recreation, and environmental benefits that depend on release from storage. Besides storage loss, many types of sediment-related problems can also occur both upstream and downstream of dams.
Reservoir sedimentation therefore is filling of the reservoir behind a dam with sediment carried into the reservoir by streams. This paper therefore describes sedimentation processes, identifies key causes, effects and mitigations of sedimentation on reservoir facilities and presents techniques that can be used to address these.

2016年9月20日 · All reservoirs are subjected to sedimentation which, without adequate prevention and mitigation counter-measures, threatens their sustainability.
ACCUMULATION OF SEDIMENT IN RESERVOIRS - Semantic …
Sediment accumulation is a major factor in reducing irrigation reservoir useful life as well as reducing the reservoir capacity. Therefore, the goal of this study was to estimate the volume of… Abstract.
