The water flow in these rivers and ditches is slow, the river channels are narrow, and the terrain around the riverbanks and channels is complex. It is not suitable for large equipment and facilities to enter the site, so personnel need to carry simple equipment to conduct water depth measurement.

[0003] At present, the two most widely used depth measurement methods in China are rubber boat manned RTK measurement and unmanned boat. Among them, rubber boat manned RTK measurement and ship manned RTK measurement are costly and consume manpower and material resources. Unmanned boats require less manpower, but transportation is cumbersome, and unmanned boats are easily blocked by debris in the water, and are not suitable for ditches and narrow rivers.
