Observation system for movement of sediment of deep riverbeds

Abstract

The invention discloses an observation system for movement of sediment of deep riverbeds. The observation system comprises a camera, a light source, an image processing system, an ultrasonic current meter and a measuring bench; the camera and the light source are matched with each other to capture movement of coarse-grained cobble and suspension movement of fine-grained sediment of the riverbeds, the image processing system receives signals of the camera and the light source and is used for processing and analyzing the signals, the ultrasonic current meter is matched with the camera and the light source and is used for measuring flow rates of the sediment in different movement states, and the measuring bench is matched with all instruments and is used for lifting the instruments under deep conditions. The effective observation system for the movement of the sediment of the deep riverbeds has the advantages that movement rules of the coarse-grained cobble, the suspension movement of the fine-grained sediment of the riverbeds and compositions of the riverbeds can be effectively observed under deep conditions, accordingly, support data can be provided for research on movement mechanisms of the sediment of the deep riverbeds, necessary conditions for riverbed revolution analysis are provided, important reference can be provided for channel regulation for deep rivers, and an observation effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of sediment research, and in particular relates to a large-water deep river bed sediment movement observation system. Background technique [0002] The regulation of river channels and the improvement of shipping conditions greatly depend on the grasp of the mechanism of water and sand movement. [0003] Scholars at home and abroad have done a lot of research on the movement of pebbles and fine-grained sediment, but due to the limited prototype observation data and the limitation of measurement methods, there are still many problems that need further research. [0004] To study the mass movement of pebbles, in addition to considering hydrological factors, physical factors such as the composition of the pebble river bed itself, the particle size and specific gravity of the pebbles are also the basic data for the study. There are not many data observations, resulting in defects in application. Part of the pro...
