Description

Technical Field

[0001] The utility model belongs to the technical field of urban waterlogging simulation, and in particular relates to a full-scene simulation facility for urban waterlogging. Background Art

[0002] With the acceleration of urbanization, urban areas are expanding, lake areas are shrinking, and a large number of permeable surfaces are transformed into impermeable surfaces. The drastic changes in urban underlying surfaces have changed the urban water cycle process, increased the runoff coefficient and accelerated the confluence time, leading to frequent urban waterlogging. Urban waterlogging simulation is an important method to clarify the occurrence and development process of urban waterlogging, and it has important practical significance for identifying the inundation range of urban waterlogging.

[0003] Currently, the urban environment is simulated through a 1:1 model. When simulating urban waterlogging, a certain amount of water needs to be discharged into the urban area after calculation to simulate urban waterlogging. However, when simulating urban waterlogging, the simulation area is open and has enough space. The simulated water will infiltrate into the ground or be discharged after the simulation, which is easy to cause direct waste of water resources and cannot be reused. Utility Model Content
