Channel is the foundation of water transportation. With the progress of society, the development of industrial enterprises, the scale of urbanization construction, and the continuous expansion of waterway route construction, the extension of the service cycle of waterways, the water environment of waterways is becoming more and more severely damaged, and it is inevitable that some silt blockages will occur, affecting the normal use of waterways. Channel dredging is very important, and underwater terrain measurement plays an important role in channel dredging. This article mainly introduces the application of underwater terrain measurement in channel dredging. On the basis of analyzing underwater measurement technology and the development history of unmanned measurement ships, this paper introduces the data collection and processing methods of unmanned measurement ships. Taking the use of unmanned survey ships for underwater terrain measurement in a certain waterway dredging project as an example, a comparison was made between the terrain before and after the dredging process. The results indicate that unmanned measurement ships have certain feasibility in channel dredging measurement. Regularly using unmanned survey ships to conduct underwater topographic surveys of dredging conditions, mastering the changes in sediment accumulation in the waterway, is beneficial for the maintenance and management of the waterway.
