Description

Technical field [0001] The invention belongs to the field of water conservancy engineering simulation test, and specifically relates to an indoor model test device and method for determining the dynamic change of the river-lake relationship in the river-lake confluence system. Background technique [0002] When rivers and lakes converge and connect, a river-lake confluence system is formed. In the field of water conservancy engineering and geographic science, the river-lake relationship is used to specifically refer to the material, energy and information exchange relationship between the river and the lake connected to it and the changes in the system structure and function caused by it. Under the influence of the inflow of the upper reaches of the river and the flow of the tributary inflow of the lake basin, the relationship between the river and the lake will undergo corresponding dynamic changes. The confluence of rivers and lakes symbiosis and co-prosperity. Only by maintai...

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
