Description

technical field [0001] The invention belongs to the field of water conservancy engineering simulation tests, and in particular relates to an indoor model test device and method for measuring the dynamic change of the relationship between rivers and lakes in a confluence of rivers and lakes. Background technique [0002] When rivers and lakes meet and connect, a river and lake confluence water system is formed. In the field of hydraulic engineering and geographical science, the relationship between rivers and lakes is used to refer to the material, energy and information exchange relationship between rivers and lakes connected to them and the changes in system structure and functions caused by them. Under the influence of the incoming water from the upper reaches of the river and the flow of the tributaries of the lake basin into the lake, the relationship between the river and the lake will undergo corresponding dynamic changes. The converging rivers and lakes coexist and p...

Problems solved by technology

However, there are obstacles to accurate measurement of the micro-scale model method in practical application. Generally, it is only possible to carry out qualitative similar simulation research on local water bodies (such as straight, curved and branched local river sections) with the help of graphics techniques such as photography and videography. It is difficult to carry out quantitative measurement of complex water bodies like the confluence of rivers and lakes
