"Three lines of defense"empowers urban flood forecasting:mechanisms and approaches
Influenced by global climate change,extreme rainfall events and urban floods have occurred more frequently over the decades.The"three lines of defense"is a basin-based rainfall-flood regime monitoring and forecasting system,consis-ting of meteorological satellites,rain radars,rain gauges,and hydrological stations.The system is of great significance to the construction of early warning management combining forecasting and monitoring and enhancing the ability of urban flood forecasting.It is necessary to promote"space-air-ground"integrated monitoring,accelerate the construction of the"three lines of defense"of rainfall-flood regime monitoring and forecasting,further extend the forecast period and improve the fore-cast accuracy of rainfall-flood regime.Based on the understanding of the"three lines of defense",this article proposes pre-liminary thoughts on the mechanisms and approaches of"three lines of defense"empowering urban flood forecasting..
