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