1. Introduction

Urban waterlogging is a phenomenon of water disaster in urban caused by rainstorm or continuous rainfall which exceeds the urban’s drainage capacity. In recent years, urbanization process changes the situation of urban earth surface coverage. The increasing waterproof ground makes most of the rain water as rivers flowing on urban ground, which caused serious urban waterlogging in many cities. Besides, rainstorm also makes urban waterlogging more and more serious, which adds the task of urban flood prevention and control, causes traffic tie-up, property loss, personnel casualties and other disasters that affect citizen’s work and life and restrict city’s development [1] .

As present, the monitoring and warning on urban’s waterlogging rely much on weather information. Waterlogging monitoring reduces to means of people check, people on vehicles check or camera check, which has the defects of slow speed, little data, poor continuity and time lag. When the rainstorm comes, that means it could not provide the waterlog information to related apartments exactly and quickly, and thus the related apartments are not able to take corresponding measures and make warnings. As to the hot topic of urban waterlog, many developed countries conduct researches in different extent, using computer aided way to monitor, forewarn and make analogue simulations. A lot of countries have built the urban monitoring and forewarning system based on their own environmental simulation model and geographic information system. Japan, a country with frequent disasters, pays much attention to urban waterlogging, and also formulates relevant laws on forewarning about disasters. It requires that governments of all levels should report on current disasters’ forecast evaluation. This paper studies the application of Internet of things in urban waterlogging management system.
