Abstract: Most gravel rivers show a tendency for characteristic grain size to decrease in the downstream direction over scales of tens or hundreds of kilometers. It has been surmised that this downstream fining is due to some ...

Abstract: Bed‐load particles tend to move downslope in response to gravity and downstream in response to fluid drag. The effect of gravity becomes particularly important when the downslope gravitational force has a component normal ...

Abstract: Most analytical models of the flow and bed topography in sinuous channels include the assumption that the secondary flow is locally adapted to channel curvature. Recently, Kitanidis and Kennedy (1984) and Ikeda and Nishimura ...

Abstract: New methods are presented for the prediction of the flow depth, grain-size specific near-bed concentration, and bed-material suspended sediment transport rate in sand-bed rivers. The salient improvements delineated here ...

Abstract: This note is devoted to the correction of an error in a calculation contained in a classical published paper on the plunging of river flows as they enter lakes or reservoirs. The correction of the error provides a felicitous ...

Abstract: In this paper the effects of density stratification in sand-bed rivers are studied by the application of a model of vertical velocity and concentration profiles, coupled through the use of a turbulence closure that retains ...

Abstract: The literature abounds with apparently conflicting relations for predicting the reference near‐bed concentration of suspended sediment or the entrainment rate of noncohesive bed sediment into suspension. Most of these ...
