“…The hydrodynamic characteristics of chute flow related to flow aeration, free surface profile and boundary layer development were studied, for example, by Ferrando & Rico , Castro‐Orgaz , and Castro‐Orgaz & Hager . Reinauer & Hager presented approach for the drawdown curve in chutes, where explicit relations for local flow depth and Froude number are given. Mohamed developed a simple method for computing pressure, energy and momentum correction coefficients from the water surface profile for accelerating flow over block stones ramp.…”

“…The stream-wise profile of the flow surface is the main objective in the hydraulic design of chutes and stilling basins (Kirkgoz et al 2009). The hydrodynamic characteristics of chute flow related to flow aeration, free surface profile and boundary layer development were studied, for example, by Ferrando & Rico 2002, Castro-Orgaz 2009, 2010and Castro-Orgaz & Hager 2010. Reinauer & Hager 1996 presented approach for the drawdown curve in chutes, where explicit relations for local flow depth and Froude number are given.…”

Turbulent chute flow was investigated experimentally and numerically for various flow conditions. The Navier‐Stokes equations are solved with the k − ε turbulence model on a structured non‐orthogonal grid. A method based on water continuity was used to calculate the movement of the water surface. Using an adaptive grid in the vertical direction, the location of the water surface was recalculated from an initially horizontal profile. After several iterations a steady solution emerged. The velocity distribution in longitudinal and vertical directions and pressure distribution along the chute were calculated. The numerical model was calibrated and verified using experimental data model studies. Reasonable agreement was found between the experimental results and that from the numerical model. Multiple‐regression equation was developed for computing the water surface profile along chute.

“…F . 3, referred to as hypercritical flow (Reinauer andHager 1996, Hager andBlaser 1998). Chute flow may become aerated if the turbulent boundary layer generated by bottom friction reaches the free surface at the socalled inception point (Cain and Wood 1981, Wood et al 1983, Wood 1991, resulting in fully-developed chute flow (Montes 1998, Chanson 2004.…”
