Abstract

The invention belongs to the field of water flow field observation and relates to a multi-space scale water flow field observation complementary method. According to the multi-space scale water flow filed observation complementary method, water vertical velocity distribution of a position where instrument is located is obtained by an ADCP flow measurement device, a surface layer flow field map with relatively fine local water is obtained through tracing and shooting trace particles by an unmanned aerial vehicle, the surface layer flow field map of the whole water is obtained by coordinate feedback of a GPS floater. A water three-dimensional observation method employing multi-scale embedment on a plane and layering in a vertical direction according to a demand is formed, and flow speed description on a flow field only by points and lines is expanded; and by the method, the problems of difficulty in water flow observation implementation, time and labor consumption, limited observation range and the like can be solved.

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...
