Abstract: An analysis of the flow through an inclined‐plane pervious substratum coupled to a turbulent, steady, uniform, and fully developed open channel flow above it is introduced. The porous material is taken to be homogeneous, ...

Abstract: An analysis of the effects of the passive plane porous bed of an open channel on the steady, uniform, fully developed, two‐dimensional turbulent shear flow is presented. The effect of the pervious boundary on the free flow ...

Abstract: The turbulent‐flow field above dunes is predicted with equations describing the transport of the kinetic energy of turbulence (k) its rate of dissipation (ε), and algebraic relations derived from a second‐moment turbulence ...

Abstract: A weakly nonlinear stability analysis of flows over erodible beds is conducted to investigate the formation of dunes. The flow is modeled with the steady vorticity transport equation and the sediment transport is described ...

Abstract: This study investigates headwall influence on local scour downstream of culvert outlets. Scour holes produced by discharging jets of varying duration and magnitude through circular culverts onto a horizontal sand bed were ...

Abstract: An investigation conducted to derive a design procedure for estimating the dimensions of scour in a variety of noncohesive materials at culvert outlets is presented. Scour hole dimensions of depth, width, length and volume ...

Abstract: Many previous studies suggest the division of total resistance into skin resistance and form resistance without direct evidence. In this study, the skin resistance, form resistance, and total resistance are independently ...
