Abstract: With the rapid development of technologies related to underwater acoustic measurement, computer, navigation, positioning and digital sensors, multibeam bathymetry technology has been widely used in engineering fields such as underwater terrain surveying and underwater building detection. The paper introduces the basic principles and system composition of multibeam bathymetry technology. Combined with the application of multibeam bathymetry technology to analysis of scour downstream of Jinping Ⅱ hydropower dam, the application of measurement results was discussed, which can provide a reference for similar scour analysis.
