The Huai Khun Kaeo watershed was chosen to study the hydrological productions from 2007 to 2013. There is lack of the hydrological observation data which can be considered as the Prediction in Ungauged Basin (PUB). It locates between the Sakae Krang river basin in Uthai Thani and the Tha Chin river basin in Chai Nat provinces, Thailand. The soil and water assessment tool (SWAT) was applied for the simulation of the hydrological response unit productions based on the Climate Forecast System Reanalysis (CFSR) from global weather data. The results of daily streamflow from the model were compared to the observed data at the hydrological observation station downstream end of the watershed. The results showed the Nash and Sutcliffe efficiency (NSE) of 0.10, correlation (R2) of 0.275, and the root mean square error (RSME) of 23.8 with a mean discharge of 11.0 cubic meters per second, respectively.
