Based on the analysis of the research achievements by various institutes,the sediment aggradation and the river evolvement in Fuling reach can be estimated during the different running phases of the Three Georges reservoir. The influence of protection dike on the flood conveying capacity and river morphology is also investigated.
The application of open-type guide work in approach channel of shiplock can adjust the velocity distribution at inlet, improve the bad flow condition, and reduce sediment aggradation, so as to make the flow condoition for navigation better at inlet.
According to the model test on the river reach where Chongqing East&West power plant lied,the sediment aggradation and river evolvement,the change of flow condition,the effect of floater on inlet were analyzed,The layout of inlet was optimized also. The results show that the intaking conditions is better and the influence of floater is smaller.
In the sediment transport module, a splitting technique is used to solve the sediment transport equation. And several sediment aggradation experiential formulas are analysed.
This article outlines the development of an optimal control methodology for minimizing sediment aggradation and degradation, thus controlling channel bed morphology, in large-scale multi-reservoir river systems.
A Late-Pleistocene periglacial region has been descended to about 2300 m asl, resulting an increase of the sediment yield of the rivers and intensified sediment aggradation in the valleys in and along the Qinling Shan.
Six classes of bank profile were identified by the end of the study period, illustrating close associations with sediment aggradation, vegetation colonization, and growth patterns.
Side-scan sonar images from the Lower Valencia Fan show that turbidite bedforms (chevrons) and net sediment aggradation vary around a small fault scarp.
Based on the analysis of the research achievements by various institutes,the sediment aggradation and the river evolvement in Fuling reach can be estimated during the different running phases of the Three Georges reservoir.The influence of protection dike on the flood conveying capacity and river morphology is also investigated.
The earthquake measuring 7.3 on the Richter Scale that occurred in central Taiwan on September 21, 1999 with epicenter located in Chi Chi has triggered a series of large_scale landslides in and around the Tsao_Lin area in Yunlin County Gukeng Township during the quake eruption, leaving behind collapsed earth and rocks that blocked the once clear riverbed of the Chishui River and a closure reservoir created at its upstream. The study was based on the simulation of NETSTARS fluvial model to research the topic...
Based on the result of model test, the sediment aggradation characteristic and bed evolvement in Baiheliang reach are analysed during the first thirty year's running of the Three Georges Project. The result provides a scientific foundation for the protection scheme of the Baiheliang carved stone.
