A study on sediment avoidance diversion and the coordinated dispatch of water and sediment at an injection-water supply project on a sediment-laden river

چکیده

Rivers in the north-western region of China have a high sediment content, and construction reservoirs on these rivers must address problem sedimentation that results loss reservoir capacity. In this study, YZD (Yazidang) was considered as typical case, to injection-type water supply Northwest China. The temporal spatial characteristics diversion project were analyzed based available 46-year data. concept ‘sediment avoidance diversion’ proposed, which reduces entry into reservoir. A one-dimensional numerical model for water-sediment coupling established, erosion deposition different operational modes analyzed. show during period large-scale siltation occurs channel. To alleviate channel, two control strategies mitigating formulated. Considering pros cons strategies, reasonable joint operation plan has been proposed extend service life This research provides theoretical basis treatment similar reservoirs.

Sediment Transport Dynamics in River Networks Induced by Water Diversion

A river network is a typical completely open system formed by interconnected river channels. The interactions between the imports of a river (water and sediment) and the channel will cause the change of the channel patterns. This is actually a feedback between the erosion and the sedimentation states of the channel via an adjustment of the sedimentcarrying capability of the stream. This feedbac...

Sediment patches, sediment supply, and channel morphology

Bed surface particle size patchiness may play a central role in bedload and morphologic response to changes in sediment supply in gravel-bed rivers. Here we test a 1-D model (from Parker ebook) of bedload transport, surface grain size, and channel profile with two previously published flume studies that documented bed surface response, and specifically patch development, to reduced sediment sup...
