Summary

The U.S. Geological Survey and the Alaska Department of Transportation and Public Facilities undertook a cooperative multiphase study of streambed scour at selected bridges in Alaska beginning in 1994. Of the 325 bridges analyzed for susceptibility to scour in the preliminary phase, 54 bridges were selected for a more intensive analysis that included site investigations. Cross- section geometry and hydraulic properties for each site in this study were determined from field surveys and bridge plans. Water- surface profiles were calculated for the 100- and 500-year floods using the Hydrologic Engineering Center's River Analysis System and scour depths were calculated using methods recommended by the Federal Highway Administration.
