river mouth treatment refers to the engineering of reforming the river into sea section by adopting the measures of improvement, dredging and other measures according to the requirements of flood drainage, shipping, irrigation, reclamation and the like. The evolution of the erosion and deposition of the estuary is the result of the interaction of the water flow, the sediment and the riverbed. Under the combined action of runoff and tide, the tidal estuary forms periodic reciprocating water flow; after the seawater meets the river water, the mixing of the saline water and the fresh water surface water bodies with different densities occurs, so that the river water flow field is more complex. River mouth silt has different sources and can be carried by upstream runoff or off-mouth coastal flow, the particle size and concentration of the silt are also different, and the river bed evolution of the river mouth is often complex and changeable. Therefore, the natural evolution of the estuary river bed often cannot meet the requirements of human development and utilization of the estuary, for example, estuary siltation influences flood discharge or shipping, and the estuary river bed needs to be treated, the water cross section is enlarged, and the river channel is deepened, so that the requirements of flood discharge and shipping can be met. And monitoring sediment deposition amount provides data basis for estuary treatment.
The sediment observation at the sea entrance is usually carried out by setting up a plurality of fixed observation sections in a downstream river channel and periodically carrying out observation. The observation range comprises two parts, namely water and underwater. The observation of the water part adopts a common measurement method. In the underwater part, for a section with wider water depth, an echo sounding instrument is usually adopted to continuously survey along the section on a survey vessel, and two theodolites are used for intermittently positioning the running survey vessel on the shore according to a front intersection method, or a theodolite flat plate instrument and a sextant are adopted to intersect and position, and a sounding hammer is used for sounding on the vessel; for the sections with narrow warehouse surface and shallower water, a rope ruler is often used for positioning and a depth measuring rod is used for measuring depth.
