Review on monitoring technology of urban road waterlogging after rainstorm and its application

Aiming at the problem of urban road waterlogging caused by the increasingly frequent extreme rainstorm events, in order to get timely and accurate water accumulation data, the technical principles and related improvements of manual monitoring, sensor monitoring, remote sensing and video image monitoring were combed from the technical level of road waterlogging monitoring technology. Advantages and disadvantages of different sensors and monitors were compared and analyzed. On this basis, the application of road waterlogging monitoring technology was summarized, and the future development trend was prospected. The analysis shows that the road waterlogging monitoring needs to make full use of the existing video equipment, improve the remote sensing water body identification technology, build a multi-source three-dimensional monitoring network and the physical digital coupling model of rain and flood based on massive monitoring data, so as to improve the level and ability of rain and flood early warning in the city in an all-round way.
