Abstract: This paper presents a study on choked flows through short, lateral contractions in subcritical open channels. A new discharge equation is developed based on the conservation of energy and experimental data with a wide range ...

Abstract: Total bed-material load computations for nonuniform sediment mixtures were evaluated for the commonly used Engelund and Hansen, Ackers and White, and Yang transport formulas. The results of sediment transport computations ...

Abstract: A computer model based on both the energy and momentum equations is developed. This generalized model can be used for the computation of water surface profiles through hydraulic jumps. It also allows computation of water ...

Abstract: The nonuniformity of bed material affects the bed-material load calculations. A size gradation correction factor

Abstract: Shear stress distribution around vertical wall abutments is studied experimentally, and maximum shear stresses that occur at the upstream corner of vertical wall abutments are determined. Shear stress distributions are ...

Abstract: Yang's unit stream power formula is modified for the computation of total bed-material load in a sediment-laden river with a high concentration of fine suspended materials. Theoretical and laboratory studies indicate that ...
