摘要
天然河道在形成过程中,受周边地貌及水沙作用的影响易形成急弯段。水流结构在急弯段发生调整,形成横向环流,造成河道凹岸进一步冲刷,需对其进行防护。以白屈港综合整治工程为例,采用数值模拟的方式对生态浅滩湿地在河道凹岸防护中的应用进行初步探索,为后续河道治理提供相关经验参考。
In the process of formation of natural river channels,it is easy to form sharp bends under the influence of surrounding landforms and water and sand.The water flow structure is adjusted in the sharp bend section to form a transverse circulation,resulting in further erosion of the concave bank of the river,which needs to be protected.Taking the comprehensive renovation project of Baiqu Port as an example,this paper preliminarily explores the application of ecological shoal wetland in the concave bank protection of the river channel,so as to provide relevant experience reference for the subsequent river channel treatment.
