Therefore, the work of dredging the river channel is imperative, the dredging is divided into the traditional physical dredging and the emerging biological dredging at present, no matter which kind of dredging is carried out, the detection of the thickness of the sludge of the small and medium rivers in the city is vital, and the detection result is also directly related to the design of the dredging scheme and the dredging effect.
