BUILDING A FLOOD WARNING AND FORECAST SYSTEM IN THE SOUTH CENTRAL VIET NAM

Tóm tắt

To raise the efficiency of warning and flood forecasting of forecasters at the Meteorological and Hydrological Station in the South Central region, Viet Nam. A system of meteorological, hydrological and oceanographic measurement stations has been installed throughout the studied area including 10 basins in 5 provinces with more than 114 stations. Data from these stations are automatically transmitted to the server associated with a model system for calculating flood levels and flood maps, then be uploaded to WebGIS. The combination of online data and WebGIS can provide immediated flood warning information; while the WRF weather forecast model system combines the MIKE FLOOD forecasting model to create flood forecast maps for river basins in the South Central region updated on the WebGIS. Users can, thus, refer to flood spots, flood statistics and download updated data from this website. The system has also helped forecasters entering data in advance and creating faster outputs. Results have helped departments and agencies make timely decisions in disaster prevention.
