DEMONSTRATION PROJECT NO. 31. HYDRAULIC DESIGN OF ENERGY DISSIPATORS FOR CULVERTS AND CHANNELS
This project involves a one-day workshop which will present design methods, and demonstrate the operation of energy dissipators for culverts and channels. The following energy dissipator types can be used to minimize many erosion problems and thereby mitigate resultant impacts on the stream environment: hydraulic jump; impact basin; riprap basin; forced hydraulic jump; drop structure; and stilling well. The workshop will include a movie which will illustrate the hydraulic principles involved in dissipating energy and will review the various classes of dissipators. A slide lecture will be presented which covers the major topics in the Hydraulic Engineering Circular #14 (HEC 14). Erosion hazards, culvert outlet velocity, flow transitions, and specific designs are discussed and illustrated. A model demonstration and a model demonstration movie will be included and participants in the problem solving workshop will use the HEC 14 to design energy dissipators for an actual field problem. Optional workshops in culvert design and stable channel design are also offered.
