Lagrangian and Eulerian Description of Bed Load Transport [PDF]
Journal of Geophysical Research: Earth Surface, 2018 AbstractSediment particles transported as bed load undergo alternating periods of motion and rest, particularly at weak flow intensity. Bed load transport can be investigated by either following the motion of individual particles (Lagrangian approach) or observing the phenomenon at prescribed locations (Eulerian approach). In this paper, the Lagrangian

Experimental study on bed load transport in the armoring process
Shui kexue jinzhan, 2018 To study the characteristics of bed load transport during armor breakup and reformation, three groups of long-duration laboratory experiments were conducted without sediment supply. Each experiment group employed a stepwise increasing discharge.

Movement of sediment over periodic bed [PDF]
Компьютерные исследования и моделирование, 2018 The movement of bed load along the closed conduit can lead to a loss of stability of the bed surface, when bed waves arise at the bed of the channel. Investigation of the development of bed waves is associated with the possibility of determining of the ...

A bed-load formula based on kinetic theory
Shui kexue jinzhan, 2013 Bed-load plays an important role in sediment transport in fluvial rivers. This paper presents a bed-load formula on the basis of kinetic theory. The pick-up rate of bed-load sediment in the formula is obtained by integrating the velocity distribution ...

Effect of bed load transport on the energy dissipation of step-pool system
Shui kexue jinzhan, 2017 Step-pool system is a typical bed micro-morphology in high gradient mountain rivers, which creates extremely high turbulence intensity and thus dissipates a majority the flow energy. The increase of the bed load transport intensity changed the flow field
