Abstract: A nonuniform, fixed‐boundary, channel‐bend flow is formulated as two coupled sets of equations, each comprising two simultaneous equations, derived from the cross‐section‐integrated equations (in circular cylindrical ...

Abstract: Sand and gravel raining from a river bed results in irregular pits on the river bed. The migration of the pits might potentially threaten the safety of downstream bridge piers and other in‐stream hydraulic structures. ...

Abstract: The hybrid integral‐differential moment and momentum model of fixed‐boundary channel‐bend flows developed in the companion paper is extended to erodible‐bed flows. The

Abstract: This paper presents a numerical model based on a multimode characteristics method for fully coupled simulation of water and sediment movement in mobile-bed alluvial channels with nonuniform bed materials. Along with the ...

Abstract: In hydraulic and hydrologic studies, engineers develop new models or calibrate existing models by various techniques. One is often concerned with the model validity regarding its ability to predict future events. Five ...
