人类活动影响下飞云江河口河床演变分析
Analysis of river bed evolution of Feiyun River estuary under influence of human activities
摘要
Abstract
Since 2000, frequent human activities had been carried out in Feiyun River Basin, such as Shanxi water conservan-cy project construction, large-scaled beach reclamation, sand mining, bridge construction etc; therefore, a series changes oc-curred at Feiyun River estuarine riverbed. Using the measured underwater topographic data before and after 2000, the river bed evolution for more than 10 years was clarified. The research showed that riverbed volume has an expansion of 11. 9% after human activities;the fluvial amplitude has been decreased, and the riverbed stability is improved. The deep grooves at river bends de-velop from close to the concave bank to the middle;the morphology at straight river section develops from"W" to"U" type. The causes that lead to such phenomenon were analyzed.关键词
