Abstract

The invention relates to a river erosion and deposition depth detection device and detection method, and belongs to the technical fields of water conservancy and hydropower engineering, engineering hydrology and river sediment dynamics. An upper end of an inner measurement rod is connected with a dome, a lower end of the inner measurement rod is connected with an inner measurement rod bottom, grooves are distributed in the inner measurement rod, the inner measurement rod is installed into an outer steel pipe, convex grooves are disposed in an inner wall of the upper part of the outer steel pipe, and the middle-lower part of the outer steel pipe is provided with a through incision; and through reading acquisition and an analysis of a scale value of the inner measurement rod, a digging and brushing depth of a flood on a river bed and a deposition depth of silt on the river bed can be conveniently and accurately obtained. A digging and brushing condition of a certain flood on a river can be measured in a condition of relatively low cost, data observation is simple and easy, and obtained data is also relatively accurate. On one hand, the device can be recycled after going through first overall installation, and can provide convenience for subsequent measurement; and, on the other hand, the device can adapt to data measurement of a complex river section, and can have high adaptability.

Description

technical field [0001] The invention relates to a detection device and a detection method for river scour and sedimentation depth, belonging to the technical fields of water conservancy and hydropower engineering, engineering hydrology and river sediment dynamics. Background technique [0002] There is currently no effective measuring instrument for measuring the depth of river erosion. There is currently no effective instrument to measure the extent to which water scours the riverbed during flooding and the extent to which the riverbed is backfilled when the flood recedes. However, detecting the maximum depth of the scour of the river bed during the flood process and the final thickness of the river bed during the flood receding process is very important for the study of river changes, sediment transport, and river sediment dynamics. However, the measurement of the maximum scour depth of the river to the flooded riverbed, and the final return to the riverbed during the flo...
