- Description
- Methods for estimating the magnitudes of peak discharges at various frequencies were developed for unregulated rural streams in western Oregon. Development of these methods had two parts: (1) fitting observed peak discharges to a theoretical probability distribution and (2) developing equations to predict the magnitude of peak discharges at various frequencies. In the first part, logarithms of annual peak discharges were fitted to the Pearson Type III probability distribution for each of 376 gaging stations in the study area. For each gaging station, based on its fitted probability distribution, estimates were made of the magnitudes of the peak discharges for recurrence intervals of 2, 5, 10, 25, 50, 100, and 500 years. All annual series of peak discharges used in this analysis were from unregulated rural streams.
