This study derived the representative unit hydrograph which is considered the discharge characteristics between upstream and downstream and has evaluated the stream gauge network using the representative unit hydrography. The representative unit hydrography is derived with the ensemble technique and transferred into probability density function for application of the entropy theory. It has been compared the case of using representative unit hydrography with the case of the conventional methodology of using empirical formula and applied to the Chungju dam basin. Summarizing the results are as follows. It can be found that the large total information content is estimated at the case of using the representative unit hydrography derived the ensemble technique more than the case of the representative unit hydrography derived the empirical formula. It means that the total information of selected stream gauge stations is represented well the discharge characteristic between upstream and downstream.
