马鞍山河段河势演变对河床及塌岸区影响

The Impact of River Regime Evolution on Riverbed and Bank Collapse Area in Ma'anshan Reach

马鞍山河段是典型微弯分汊型河道形态,其江心洲众多,左、右汊分流比波动大,深泓线左、右摆动,发育形成了多分汊型河道,对河床、河道内崩岸区影响较大,因此需定期对河道进行地形测量、水文测验、水文资料的收集(分析),以充分掌握河床、河势动态变化情况及崩岸区的岸线稳定性,为河道管理提供决策资料和科学依据。

Ma'anshan reach is a typical slightly curved branching channel shape.There are many Jiangxin Island in the center of the river,the diversion ratio of the left and right branches fluctuates greatly,and the thalweg swings left and right,forming a multi branched river channel,which has a great impact on the riverbed and the bank collapse area in the river channel.Therefore,it is necessary to conduct regular topographic surveys,hydrological tests,and collection(analysis)of hydrological data on the river channel,in order to fully grasp the dynamic changes of the riverbed and river regime,as well as the stability of the shoreline in the bank collapse area,and provide decision-making data and scientific basis for river management.
