Abstract

The invention relates to a self-stabilizing high-precision sediment mass measurement system and a measurement method. The measurement method includes determining the measurement river section, selecting the measurement section, planning the position of the sounding ship, placing the sounding ship in place, preparatory work for the measurement, Simultaneously start measuring, processing raw data, and calculating and outputting results at two points. The present invention obtains the movement form and characteristics of sand waves on the surface of the river bed through stable and accurate measurement of the river bed shape in the river section, so as not to interfere with the original sand transport and water flow of the river bed. Under these conditions, the real-time and accurate measurement and analysis of the single-width mass-sediment rate of the river bed can be carried out.

Description

technical field [0001] The invention relates to a self-stabilizing high-precision sediment mass measurement system and a measurement method, which belong to the related technologies of water conservancy projects. Background technique [0002] Push mass, also known as bed sand load, bottom load, push load, and traction load, refers to the sediment particles that roll, move, jump or move in layers along the river bottom in the water flow. (referred to as bed sand) is often exchanged, which is one of the key issues in sediment research; in mountainous rivers, the movement intensity of rolling and jumping is often very large, making the material exchange between sediment and river bed particularly frequent , which has a huge impact on the change of the riverbed surface shape, so the study on the sediment transport rate of the flow mass is of great significance, and, in many hydraulic projects, the flow mass is the main factor of reservoir siltation and channel blockage , so the...
