Embodiment Construction

[0065] Since storm surge disasters have been listed as an important factor threatening the safety of citizens, these ocean physics models are dedicated to solving the urban flooding problem caused by storm surges in coastal urban areas. In 2013, Zheng et al. assessed the correlation between extreme rainfall and storm surges along the Australian coastline14 using a binary logic threshold excess model. In 2015, Jacob et al. simulated hurricanes using the ADCIRC model (Advanced Circulation Model) and the Simulated Nearshore Waves (SWAN) model, and analyzed the impact of storm surge on Galveston rainfall in the Houston area. In 2018, Xu et al. simulated a storm surge in Haidian District, China, using a maximum sustained wind model and a personal computer storm water management model, and estimated the expected economic loss. These studies discuss the impact of heavy rainfall in urban areas. However, in practice, a large number of factors in the city can affect the torrent, seriou...

Abstract

The invention provides a pipeline diameter determination method and an urban inland inundation early warning method and device, and relates to the technical field of urban inland inundation treatment.The method comprises the following steps: acquiring diffusion amount data in seawater; obtaining urban drainage system parameters and urban rainfall data; establishing a mapping relationship betweenthe pipeline diameter in the urban drainage system and the urban accumulated water depth according to the seawater internal overflow data, the urban rainfall data and the urban drainage system parameters; acquiring detection data of the urban accumulated water depth; and determining the diameter of the pipeline through a Markov decision process according to the mapping relationship between the diameter of the pipeline and the urban ponding depth and the detection data of the urban ponding depth. According to the method, the urban ponding depth is obtained through the seawater internal overflowdata and the urban rainfall data, then the urban ponding depth is compared with the detection data of the urban ponding depth, and the pipeline diameter is estimated through the Markov decision process, so the underground pipeline diameter can be estimated, and the modeling precision of storm surge flood simulation is improved.

Description

technical field [0001] The invention relates to the technical field of urban waterlogging control, in particular to a method for determining the diameter of a pipeline, an urban waterlogging early warning method and a device. Background technique [0002] Since storm surge disasters have been listed as an important factor threatening the safety of citizens, the ocean physics model is dedicated to solving the urban flood problem caused by storm surges in coastal urban areas. [0003] During storm surges, IoT sensors distributed in urban areas can be used for flood detection. These sensors are set up in various areas of the city to monitor the depth of accumulated water in the city to help in the modeling of urban flooding. However, since the pipeline is located underground, its degradation Status is difficult to identify. [0004] Therefore, there is an urgent need for a method that can estimate the diameter of underground pipelines. Contents of the invention [0005] The...
