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: The water quality of Dianchi Lake has deteriorated in the last 50 years due to excessive human activities. The Niulan River to Dianchi Lake Water Diversion Project (NRDLWDP) was implemented in 2013 to improve the water ...

Abstract: This paper presents a study on the reservoir sedimentation processes in response to changes in incoming flow at the upstream and changes in the pool level at the downstream for Sanmenxia Reservoir, which is located on the ...

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

Abstract: The drift velocity, at which sediment disperses relative to the motion of water-sediment mixtures, is a key variable in two-phase mixture equations. A constitutive relation for the drift velocity, expressed as a power ...

Abstract: Bank erosion frequently occurs in the Lower Yellow River (LYR), playing an important role in the evolution of this braided river. A two-dimensional (2D) composite model is developed herein that consists of a depth-averaged ...

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 ...

Abstract: Reservoir management strategy optimization requires benefit calculations based on reservoir storage, which is variable because of sedimentation. It is therefore necessary to express reservoir benefits as a function of ...
