多波束测深系统在河床变化分析中的应用

河道变化情况与变化趋势是河道防洪、通航、水文等分析的重要因素。特别是在河道水情复杂和险工险段处，其河床变化复杂，规律难寻，对通航安全、防洪排涝、水利工程设施稳定性等影响深远。根据具体实测数据研究了多波束测深体系在河床变化分析中的应用，探索了多波束测深系统在内河河底地形数据采集及数据处理及分析的方法，形成了一种基于多波束测深系统的河底地形数据进行河床变化的反演分析的思路。

Application of Multi-beam Sounding System in Analysis of Riverbed Change

The change situation and change trend of river are the important factors in the analysis on the flood control, navigation and hydrology of river. Especially in the river water situation complex and dangerous sections, the changes of the riverbed are complicated and the rules are difficult to find, which have a far-reaching influence on the navigation safety, flood control, waterlogging drainage, and the stability of hydraulic engineering facilities. The application of multi-beam sounding system in the analysis of riverbed change is studied according to the detailed measured data. The methods of multi-beam sounding system in the topographic data collection, data processing and data analysis of the inland river bottoms are explored. And a method of inverse analysis of riverbed changes based on the data of river bottom topography from the multi-beam sounding system is developed.
