What is the Flood Control Integrated Information System?

 Observation data such as rainfall amount, river water level, tide level, etc. are automatically collected real time from the rain gauges/water gauges installed around the city, processed and displayed on a map or in report tables. The river image data are also displayed.
 Besides, other information such as weather warning/alarm, sediment disaster alert information, flood forecast, etc. is also displayed real time.
