“…Preliminary Flood-Frequency Relations for Urban Streams in Metropolitan Atlanta were presented by Golden (1977) based on a technique developed by Sauer (1974) that used the natural flood-frequency and rainfall-frequency characteristics of local areas in Oklahoma. Urban floodfrequency relations from natural flood-frequency relations were developed by Sauer (1974) by adding factors to account for local rainfall-frequency characteristics, the percentage of impervious area in a basin, and the percentage of a basin served by storm sewers.…”
