Water resources bulletin, 3. Flow capacity of culverts on oregon coast range forest roads [texte imprimé] / Piehl, B. T. ; Pyles, M. R. ; Beschta, R. L. . - U.S. Department of the Interior - Geological survey . - [S.l.] : U.S. Department of the Interior - Geological survey, 1988. ISSN : CI-08010 One hundred twenty eight stream-crossing culverts in the central oregon coast range were evaluated for peak flow capacity and were compared with current design guideliness. Their ability to pass the 25 year peak flow, as mandated by Oregon state forest pratice rules, and their maximum flow capacity were determined. Over 40 percent of the culverts were unable to pass the 25 year peak flow at a headwater to diameter ratio of 1. About 17 percent could not pass 25 year peak flow without headwater overtopping the roadfiel. Langues : Anglais (eng)
