Embodiment Construction
[0039] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0040] Such as figure 1 As shown, the present invention provides a method for monitoring and calculating the amount of river silt, comprising the following steps:
[0041] S1: Install a reference station on the bank of the river to be measured, and design the survey line;
[0042] S2: Use GPS RTK technology to obtain the coordinates of the phase center of the GPS antenna at the detection point of the reference station and the elevation of the lowest underwater point;
[0043] S3: Use multi-beam bathymetry technology to conduct precise measurement of the underwater terrain of the river to be measured, and obtain a three-dimensional model of the underwater terrain;
[0044] S4: In the 3D model, the amount of river silt is calculated according to the coordinates of the phase center of the GPS antenna at the detection point and the elevation of the lowest ...

The invention discloses a method for monitoring and calculating river silt volume, which comprises the following steps: S1: install a reference station on the bank of the river to be measured, and design a survey line; S2: use GPS RTK technology to obtain the detection location of the reference station The coordinates of the phase center of the GPS antenna and the elevation of the lowest underwater point; S3: use the multi-beam bathymetry technology to carry out precise measurement of the underwater terrain of the river to be measured, and obtain the 3D model of the underwater terrain; S4: in the 3D model, according to the detection position The coordinates of the phase center of the GPS antenna and the elevation of the lowest underwater point are used to calculate the amount of river silt. The river channel silt monitoring calculation method of the invention is helpful to understand the river channel silt situation, and is beneficial to water pollution monitoring and control. Compared with the traditional river silt monitoring calculation method, the advantage is that the detection of silt coverage is better, and the measurement of the thickness and volume of river silt can achieve high accuracy, which is of great significance to river channel and sewage treatment.
Description
technical field [0001] The invention belongs to the technical field of river channel monitoring, and in particular relates to a method for monitoring and calculating the amount of silt in a river channel. Background technique [0002] With the rapid development of social economy and urbanization, the problem of silt accumulation in river basins has become increasingly prominent. The accumulation of silt will cause the water level of the river to rise, causing certain harm to residents and buildings around the river. At the same time, the accumulation of silt has caused certain pollution to the water environment of the river. If the external pollution source of the river is cut off, the pollutants in the river silt will be released to cause secondary pollution of the river. Therefore, the monitoring and calculation of the amount and thickness of silt in the river It is a hot spot and difficult problem for scholars at home and abroad. Full-coverage monitoring and accurate me...
