Channel form discharge which determines shape and character of a channel is named as dominant discharge. Assuming that fixed discharge flows in the fluvial plain for a long time, it is channel form discharge of a certain channel if it changes the fluvial plain into shape of the channel. Channel form discharge can be demonstrated by concept of bankfull or effective discharge. 1.01, 1.58, 2, 2.33 and 5 year flood discharge were used in order to determine channel form discharge. Each frequency discharge was determined by 80 year flood discharge by a research result conducted by Kim and Won. 1.01 year frequency discharge was selected as the most similar discharge to bankfull discharge. 1.58 year frequency discharge habitually used in Korea exceeded bankfull discharge.
