Abstract: For the small hydropower stations in the Xue River basin of Hunan Province, UAV aerial photogrammetry and USV-based underwater topography survey technology are used to accurately collect river channel topography and construct high-precision terrain models. By overlaying and analyzing digital surface models and digital orthophoto maps, the main cross-sections of the principal river are extracted, the issue of mismatched hydrological data is addressed, and the accuracy of the data through post-processing is ensured, so as to provide more reliable data for river management and environmental protection.

Key words: unmanned aerial vehicle(UAV), unmanned surface vehicle(USV), aerial survey, cross-section extraction
