Abstract
Description
technical field
[0001] The invention belongs to the technical field of urban drainage, and more specifically relates to an artificial simulated rainfall device for generating relatively complex rain patterns such as Chicago rain patterns. Background technique
[0002] The natural rainfall process usually has uncertainty in time and uncontrollability in intensity. By artificially simulating rainfall, a certain amount and intensity of rainfall can be artificially produced, which shortens the experimental period and speeds up the project research plan. At present, the country is piloting the construction of sponge cities, and the reduction and control of urban surface runoff and the reduction of non-point source pollution are one of the main goals. It is very important and urgent to grasp the law of surface runoff and the performance of low-impact development facilities.
[0003] Artificial rainfall simulation devices are widely used in the research of soil erosion and other ...
