Flood Forecast
Forecast Dissemination Procedure
Hydrologic data wirelessly transmitted in real-time from the observation stations are sent automatically to the computer of Yeongsan River FCO. After that, the water level of rivers and flooding scale are calculated for the flood forecasting areas.
When water level rises over defined point, we announce flood-warning or flood-alarm to the public through the mass media (broadcast, newspaper, etc) and related agencies so that citizens can prepare and evacuate against flood.
