Description

technical field [0001] The invention relates to the technical field of calculation of water quantity at a large drop edge, in particular to a vertical layered coupling method, system and terminal of a two-dimensional hydrodynamic model. Background technique [0002] During the planning and design process of the "sponge city", a two-dimensional hydrodynamic model is used to analyze the sponge measure of "green roof". Due to the high difference between the roof and the ground, the model is difficult to stabilize in places with such a "big drop" Calculate the amount of water, so how to solve this difficulty in the model needs to be solved urgently. [0003] When a two-dimensional hydrodynamic model encounters a place with a straight up and down and a large drop between the "roof" and the "ground", it is difficult to ensure that the model can stably and accurately simulate the "roof" inflow The amount of water reaching the "ground" will even cause too many grids in the entire s...
