Abstract

The invention belongs to the field of water body flow field observation and is a multi-spatial-scale water body flow field observation complementary method. The technical solution is: the vertical flow velocity distribution of the water body at the position of the instrument is obtained through the ADCP flow meter, and the tracer is tracked and photographed by an unmanned aerial vehicle Particles can obtain a relatively fine surface flow field map of the local water body, and the surface flow field map of the entire water body can be obtained through the coordinate feedback of the GPS float. Using the above three flow field observation methods at different spatial scales to complement each other, a three-dimensional water body observation method that is multi-scale nested on the plane and can be layered vertically according to needs is formed. This method can solve the problems of difficult implementation of water flow field observation, time-consuming and labor-consuming, and limited observation range.

Description

technical field [0001] The invention relates to the field of water body flow field observation, in particular to a multi-space-scale water body flow field observation complementary method. Background technique [0002] The flow field is the main parameter to describe the spatial dynamic characteristics of the water body, reflecting the flow velocity and flow direction of the water body within a certain space range. At present, due to technical limitations, fixed-point or navigable section observations are mainly used for flow field observation of large water bodies, and the observation range is limited to a few points or sections. Time-consuming and labor-intensive. There is an urgent need for an observation of the water flow field at different spatial scales. Contents of the invention [0003] The present invention provides a multi-spatial scale water flow field observation complementary method, which is used to overcome the limitations of the prior art that the water f...
