Includes bibliographical references. "On November 15, 1983 runoff from heavy precipitation caused considerable erosion of the stream channel at the stream gauging station on Chapman Creek above Sechelt Division. This high flow changed the stage-discharge relationship developed to that date. The lack of present high stage-discharge measurements had created a problem in developing a new relationship. This problem has been solved with the guidance of channel conveyance computed from discharge measurements taken at medium stage and the rating curve extension has been computed by the use of a stage-discharge equation. An indirect measurement program is required to verify the value of Manning's 'n' in this study"--Abstract, p. i. gccst Hydrometry gccst Streams Neufeld, I. J. Canada. Environment Canada. Canada.
