CIVL4120 Advanced open channel hydraulics and design - TUTORIAL Part 3 - Hydraulic design of spillways 3.1 An overflow spillway is to be designed with an un-gated broad-crest followed by a stepped chute and a hydraulic jump dissipator. The width of the crest, chute and dissipation basin will be 75-m. The crest level will be at 70.0 m R.L. and the design head above crest level will be 2.4 m... • Conveyance of a channel increases with the hydraulic radius (wetted perimeter deceases). From Manning’s formula. • The best hydraulic section is a semicircle (for a given area it has the minimum wetted perimeter). • For a specific cross section, the proportion that produce the best hydraulic section (maximum flow) might be derived. • The best hydraulic section might not be the best

Open channel spillway. Main article: Open channel spillway. Chute spillway . A chute spillway is a common and basic design which transfers excess water from behind the dam down a smooth decline into the river below. These are usually designed following an ogee curve. Most often, they are lined on the bottom and sides with concrete to protect the dam and topography. They may have a controlling

Types. A spillway is located at the top of the reservoir pool. Dams may also have bottom outlets with valves or gates which may be operated to release flood flow, and a few dams lack overflow spillways and rely entirely on bottom outlets.

  • (similar to open channel drop structures), while severe pressure differentials around the inlet can cause structural failure of the inlet apron. See Figure B3.6.
  • The Reynolds number of an open-channel flow is defined as Re = 4RV/?, where the kinematic viscosity ? has been given above. It expresses the ratio of inertial forces to viscous forces. With R in m and V in m/s, Re = 2667RV. In nearly all practical cases, Re >> 1, so the flow is turbulent.

  • The basic approximation in open channel hydraulics, which is usually a very good one, is that variation along the channel is gradual. One of the most important consequences of this is that the pressure in the water is given by the hydrostatic approximation, that it is proportional to the depth of water above. In Australia there is a slightly non-standard nomenclature which is often used
