5 International Flood Network (IFNet) was officially established during the WWF3 in Kyoto March 2003

6 General Meetings of IFNet are held annually, their dates and venues being decided jointly by the Chairperson and the Director General. The 1 st General Meeting 10 August 2003, Stockholm

7 Schedule after Establishment 10 August, 2003 The 1 st General Meeting in Stockholm March, 2004 The 1 st Preparatory Meeting for the WWF4 March, 2005 The 2 nd Preparatory Meeting for the WWF4 Summer/Autumn 2005Regional Meeting November, 2005 Advance Meeting for WWF4 March, 2006 WWF4

8 Global Flood Alert System ( GFAS ) One of the activities of IFNet implemented by - Ministry of Land, Infrastructure and Transport (MLIT) - National Space Development Agency (NASDA) and - Infrastructure Development Institute (IDI)

9 On-Line Data Processing System Data for climate forecasts (realtime/near-realtime data) 3-hour global precipitation map (realtime/near-realtime data) Heavy rain around the Upstream of River Rainfall Prediction Flood Prediction Secretariat of IFNet Flood may occur in the downstream of River. Around the downstream of river It is heavy rain in the upstream of River. There is a possibility to occur a flood in X hours. Please evacuate to safe places.
