Magnitude and Frequency of Floods on Small Rural Streams in Alabama

摘要

The purpose of this report is to update previous flood-frequency reports for Alabama by providing an alternative method of estimating the magnitude and frequency of floods for small rural streams, and to provide frequency estimates of water year peak flow data at streamflow gaging stations using peaks collected through September 2003. This report includes regression equations for estimating the magnitude of floods for streams having recurrence intervals of 2, 5, 10, 25, 50, 100, 200, and 500 years for ungaged rural streams. These equations are applicable for streams having drainage areas less than 15 mi(sup 2).
