无堤防河段河道管理范围划定技术分析

Technical Analysis on Delimitation of River Management Scope in Non-embankment Reach

在河湖管理范围划定工作中,无堤河段占比大,且易受地形、岸坡植被、建筑物等影响,是划界工作的重点和难点。为解决无堤防河段河道管理范围划定工作中的难题,提高生产效率,该文以德庆县悦城河为例,结合无人机航测、无人船河道断面测量技术,提出了无堤防河段设计水位与岸坡交线的自动化快速生成技术方案,供技术人员交流和参考。

In the delimitation of the management scope of rivers and lakes,river sections without embankments account for a large proportion,and were easily affected by topography,bank vegetation,buildings,etc.,which were the key and difficult points of the demarcation work.In order to solve the management scope of river sections without embankments To identify problems in the work and improve production efficiency,this article took the Yuecheng River in Deqing County as an example,combined with drone aerial surveys and unmanned ship channel cross-section measurement technologies,and proposes the intersection of the design water level and the bank slope of the river section without dikes.The automated and rapid generation of technical methods is for technical personnel to exchange and reference.
