Abstract
The Geological Survey has conducted tests in the hydraulics laboratory at the Georgia Institute of Technology to determine the discharge characteristics of highway bridges with spur dikes. The addition of spur dikes to a contraction reduces the resistance to flow and increases the discharge coefficient 33% for elliptical dikes, 23% for straight dikes, and 27% for timber dikes. Adjustment factors for the discharge coefficient have been defined for the addition of elliptical and straight dikes to spill through contractions for various channel contractions and ratios of dike length to bridge opening.
