Construction of Urban Stormwater and Flood Management Platform


SIDRI eliminated flooding and waterlogging problems in Jiujiang, Jiangxi, China by creating a CNY 8 billion hydraulic analysis system.

Construction of Urban Stormwater and Flood Management Platform

SIDRI created a reality model that incorporates detailed hydraulic information and enables them to determine the impact of numerous what-if scenarios.



In 2020, significant flooding along the Yangtze River killed 141 people and displaced 38 million more. For the city of Jiujiang, the disaster was the latest in a string of overflow and waterlogging incidents caused by accelerated urbanization, and officials initially could not determine how to prevent them. To better prepare for future flooding events and minimize disruption to city life, China Three Gorges Corporation directed SIDRI to create a hydraulic analysis system that can simulate a variety of water conditions in the city. Officials can now identify and address critical drainage problems in advance. With this information, they have optimized their emergency response plan and determined the type of infrastructure they need to improve water flow, protect residents, and prepare the city for future weather-related events.
