Establishment and Application of Drainage Warning Rainfalls

Establishment and Application of Drainage Warning Rainfalls

Establishment of warning rainfalls at inundation-prone area needs to consider the influence of downstream river water level, previous rainfall, real-time rainfall, and 1-2 hour lead-time rainfall estimated by QPESUMS. Increase of rescue time and decrease of inundation damage can be achieved through the establishment of the warning rainfalls.
