Preliminary flood-frequency relations for small streams in Georgia

Effects of urban flood-detention reservoirs on peak discharges in Gwinnett County, Georgia

“…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.…”

Flood-frequency relations for urban streams in metropolitan Atlanta, Georgia

“…This was done by the multiple-regression method and will be described in a later section of this report. Golden (1977) presents preliminary flood-frequency relations for urban streams in Metropolitan Atlanta. His method is based on the technique used by Sauer (1974) for other parts of the United States, and on the natural flood-frequency and rainfall-frequency characteristics of the local area.…”

“…Jones (1978) developed simplified equations that can be used on small watersheds (up to 200 acres) to estimate the expected peak-flood flows. Results from this study were compared with results using the Golden (1977) method, and several other methods (Jones, 1978). These methods were not generally compatible with the equations presented in Jones 1 study.…”
