With the continuous advancement of urbanization and the increasing frequency of heavy rainfall, a series of factors such as urban surface hardening, decreased water seepage capacity, and drainage networks that cannot meet current demands are leading to increasingly severe urban flood disaster problems. In July 2021, persistent wide-scale rainfall occurred in many places in Henan, and the infrastructure of many cities was overwhelmed, with serious road waterlogging and public transportation paralysis.

Extreme heavy rainfall is a comprehensive test of the protection capacity of urban drainage systems. How should we strengthen the monitoring and warning of urban waterlogging? Istrong Technology, with twenty years of industry experience, has developed a rainstorm secondary disaster risk warning system, which includes an urban waterlogging warning system and a rural rainstorm secondary disaster risk warning system, achieving good application results.

Waterlogging Monitoring

Based on the integrated waterlogging monitoring instrument independently developed by Istrong Technology, it can perceive the waterlogging depth of urban flood-prone points in real-time, combined with real-time monitoring data of urban rivers and networks, as well as meteorological data such as rainfall and radar, to monitor urban waterlogging in real-time.

Waterlogging Forecasting

Based on basic information such as urban rivers, networks, DEM, etc., combined with real-time monitoring data such as rainfall, water level, and rainfall forecast data, a city waterlogging prediction model that integrates a one-dimensional sewer model and a two-dimensional fast overland flow model is constructed to predict urban waterlogging, dynamically simulate the process of urban waterlogging water accumulation and inundation, and also simulate historical waterlogging and waterlogging under typical rainfall frequencies.

Waterlogging Warning

According to the waterlogging prediction results, quickly generate a waterlogging warning announcement and publish it to relevant departments and society through fax, SMS, public numbers, etc.

Istrong has been committed to the informatization field of disaster reduction and prosperity for twenty years, has rich project construction experience, based on IoT, cloud computing, GIS, automatic control, communication, big data, and other technologies, develops more informatization systems suitable for multiple scenarios, professional, intelligent, multi-dimensional, integrated graphics and text, to provide support for the digital construction, online monitoring, scheduling, and decision-making of municipal facilities.
