Fontenelle Dam Flow Deflectors for Mitigating Abrasion Damage (final, PDF, 572KB)
By Leslie Hanna
Report completed on June 21, 2011

A physical hydraulic model study was conducted to evaluate the hydraulic characteristics of the Fontenelle Dam river outlet works stilling basin and to design a flow deflector or a series of flow deflector panels for the purpose of mitigating basin abrasion damage. The Fontenelle basin has a width of 62 feet that spans a distance much greater than any basin previously studied. As a result, the project presented the additional challenge of designing a deflector for the nonuniform flow condition
