Abstract
Traditional culvert applications were designed by determining the minimum culvert size that will pass the specified design flood. In recent years, culvert performance objectives and designs have been expanded to include other considerations such as improving fish and/or terrestrial animal passage and rehabilitating old, deteriorated culverts. This project evaluated culvert geometries associated with these new applications to develop the hydraulic relation-ships, including loss coefficients. The report will be of interest to hydraulic engineers and environmental staff. (Author/publisher)
