主　　题：Underwater Topography RTK-GPS Echo Sounder 

摘      要： This study focuses on change of topography in a water area. Output data from a GPS unit and an echo sounder data were incorporated into analysis for construction of underwater topography. Comparison of two data sets lead to conclusion concerning sedimentation during period from January 2020 to January 2021.
