Description

Technical Field

[0001] This invention relates to the field of water depth detection technology, and in particular to a water depth measurement device for tidal bifurcation river channel regulation and shoal. Background Technology

[0002] Tidal distributary sections of waterways accumulate silt, forming sandbars and shoals that severely impede navigation. Therefore, it is necessary to remove these silt-laden sandbars and maintain the river environment.
