This study aims to compare and analysis the bankfull discharge of the Bocheong stream on the basis of four methods and this intends to develope the channel management. Four methods are as follows; 1. Rating Curve 2. Hydraulic Geometry 3. Flow Frequency (Annual Series) 4. Gauckler-Manning Formula Flow frequency method from among the above- methioned have been recognized as a reasonable method than others. This study is on the basis of this the the results as follows ; 1) In the whole, the discharge ranks Gauckler-Manning formula, hydraulic geometry, rating curve and the bankfull discharge increases to go down from upstream to downstream. 2) Hydraulic Geometry is high the degreest than other methods and is judged to be possible in the Bocheong stream. 3) A bankfull discharge outputed to rating curve gains littler than it outed to other methods. 4) If a design considers safety, Gauckler-Manning formula utilized to miss records is possible to use in the Bocheong stream.
