Design and Construction of Urban Stormwater Return Flow Design Platform Based on Big Data Platform

Abstract

The stormwater system is an important infrastructure for the city, playing an important safety role in reducing and removing water from roads and avoiding urban flooding. With the acceleration of urbanization and the accentuation of urban heat island effect, urban surface runoff shows the trend of high flow rate and fast flow rate, which leads to the increase of drainage load of urban stormwater system and the increase of risk of urban flooding. Therefore, it is necessary to adopt a scientific method to conduct a comprehensive analysis of the overall drainage capacity and safe conveyance capacity of the urban stormwater system, so as to do the preliminary paving work for the transformation of the existing stormwater system and improve the urban drainage capacity. In this paper, based on the analysis of the current status of urban stormwater system, the concept of urban stormwater system vulnerability is proposed and the indicators of stormwater system vulnerability are determined.
