Sedimentation Characteristics and Impact Analysis of Typical Channel-type Reservoir
摘要
Abstract
Changtan Reservoir located in Meizhou City,Guangdong Province,which is a typical channel-type reservoirs.Based on the measured cross-sectional topographic data and reservoir capacity curve,the sedimentation characteristics and the impact on flood control and power generation of typical channel-type reservoir was analyzed.The results show that from 1987 to 2022,the siltation volume of Changtan Reservoir at the normal high water level(148 m)is 18.4 million m3,the siltation rate is 16.08%,and the total reservoir capacity loss rate is 13.03%,which is lower than that at the beginning of reservoir operation period(1987-1995).The sedimentation of Changtan Reservoir is in the form of banded sedimentation,and the sediment particle size varies from coarse to fine from the tail to the front of the dam.Affected by the siltation of the reservoir,the maximum flood level in front of the dam in 2022 increased compared with that in 1987 under the same flood conditions,but the added value was small,and the siltation elevation of the pre-dam section was about 25 m lower than the inlet of the unit,and the sediment particles were generally finer,so it was considered that the current sediment sediment in Changtan Reservoir had little impact on flood control and power generation.关键词
