Abstract: In 2011, Thailand witnessed its worst flooding in half a century and its impact on manufacturing industry has caused great losses on Thailand economic. It clearly reflects the climate variability that become more intense and extreme. It also reveals the reliability and limitation of weather forecast that can be accurately predicted as far out as 7 days. Redundancy and inconsistency of observation data also lead to difficulties and delay of data analysis. Therefore it is necessary to develop an National Hydro informatic and Climate Data Center (NHC) and operational flood forecasting model with decision support system (DSS) for the Chao Phraya river basin. The objective of center is to establishing flood management platform and system for Chao Phraya river basin based on information technology developed mostly from national own technology. The system comprises of Information, Data Integration System, Analysis and Dissemination part including early warning system. Monitoring and reporting water situation can automatically produced hydrological situation report on daily basis. The forecast results including rainfall from Weather Research and Forecasting (WRF) with high resolution. The flow along main river is measured and updated so that the current flood situation can be investigated closely. Flood forecasting system under a DSS can simulate the Chao Phraya river flow 7-days in advance with an accuracy of about 60-80%. The discussion among experts from responsible government agencies has been mode for immediate action on flood management based on the above mentioned data.
