基于UAV与ADCP航测地形数据的河道高精度模拟应用

High-accuracy Simulation of River Channels Based on UAV and ADCP Photogrammetric Topographic Data

采用无人机和ADCP无人船对湖南省境内资江某河段进行航测,将得到的地形高程数据(DEM)插值到计算网格中,通过对该河段进行数值模拟,可得到该河段某一时刻的流场及水位变化情况。基于UAV与ADCP航测地形数据的河道高精度模拟可用于河道的通航论证、防洪评价等,将为相关河道工程建设提供数据支撑与参考。

UAV and ADCP unmanned ship are used to carry out aerial photography of a reach of Zijiang River in Hunan province.The obtained digital elevation model(DEM)is interpolated into the calculation grid.Through numerical simulation of the reach,the flow field and water level change of the reach at a certain time can be obtained.The high-accuracy simulation of river channel based on UAV and ADCP aerial photography topographic data can be used for navigation demonstration and flood control evaluation of river channel,which will provide data support and reference for related river channel engineering construction.
