Includes bibliographical references (pages 17-18). "A method of regional flow analysis is provided to estimate the magnitude and frequency of floods for streams in Northeastern British Columbia. The annual series of peak flow data from 26 stream gauging stations on unregulated streams were used to determine a log Pearson Type III frequency curve for each station. Flood magnitudes having recurrence intervals of 5, 10, 25, 50 and 100 years were related to the Mean Annual Flood (2.33 year). These ratios were used to develop a regional frequency curve. The entire area was represented by one regional curve. The drainage area vs. Mean Annual Flood was represented by three regions; plateau; mountains and foothills south; and mountains and foothills north"--Abstract, page iii. Includes abstract in French.
