-Movements of masses of bodies of soil, bed rock, rock debris, soil, or mud which usually occur along steep-sided hills and mountains because of the pull of gravity Creep -Slow downslope movement of particles that occurs on every slope covered with loose, weathered material. One of the most difficult problems encountered in open-channel hydraulics is the determination of the rate of movement of bed material by a stream. The movement of bed material is a complex function of flow duration, sediment supply, and channel character- istics. If a .

Lake - Lake - Sediments and sedimentation: Lake sediments are comprised mainly of clastic material (sediment of clay, silt, and sand sizes), organic debris, chemical precipitates, or combinations of these. The relative abundance of each depends upon the nature of the local drainage basin, the climate, and the relative age of a lake. The sediments of a lake in a glaciated basin, for example. The Cretaceous Afikpo sedimentary Basin in Southeastern Nigeria contains rocks of fluvial, deltaic and shallow marine origin. This study examines the role of sedimentary processes in sediment distribution in the various geologic environments. The outcrop sections and the Afikpo River were studied by visual observation and photographing of important features during a field mapping .

Sediment transport is the movement of solid particles (sediment), typically due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained.
For the purposes of aquatic monitoring, sediment can be classified as deposited or suspended. Deposited sediment is that found on the bed of a river or lake. Suspended sediment is that found in the water column where it is being transported by water movements.
Suspended sediment is also referred to as suspended matter, particulate matter. An empirical formula is proposed to consider the effects of the gravity on the sediment transport capacity and the bed-load movement direction in channels with steep slopes.
Flow and sediment transport are simulated in a decoupled manner, but the sediment module adopts a coupling procedure for the computations of sediment transport, bed change.
The book examines the processes of erosion, transportation, and deposition of sediment particles under gravity, flowing water, waves, and wind.

Certain Formulae for Bed Load Transport Einstein’s [ ]. Conclusions & Discussion Open Channel Flow. Dey () gives an overview of bed load transport and suspended load transport equations for open channel flow. In open channel flow there is always the assumption of a stationary bed, the assumption of a 2D flow above the bed and a more or less known velocity profile above the bed.
Sediment deposition is responsible for creating alluvial fans and deltas, but excessive accumulation of sediment can build up channel plugs and levees.
These deposits then block the river from reaching other stream threads or floodplains Increased sedimentation is considered one of the primary causes of habitat degradation 6 - Introduction to sediment transport in open channels, Pages 7 - Sediment transport and sediment properties, Pages ,I-VIII 8 - Inception of sediment motion — occurrence of bed load motion, Pages 9 - Inception of suspended-load motion, Pages 10 - Sediment transport mechanisms: 1.

As the result, the proposed stochastic jump diffusion particle tracking model (SJD-PTM) can model the movement of sediment particles in two-dimensional open channel with time.

Hughes, in Treatise on Geomorphology, Sediment transport is the mechanism that translates the work of hydrodynamic processes into morphological change. This chapter discusses the transport of noncohesive sediment in wave-dominated settings.
Following an introductory section, techniques for measuring sediment transport are described, providing context for the following. Book Reviews; Published: May ; Sediment movement in open channels.

To capture the spatial heterogeneity of sediment motion, the imaging window contained an integral number of the repeated pattern of dowels (Figure 1a). To eliminate distortions in the image due to water surface movement, a small glass tank was positioned above the channel and extended less than 1 cm below the water surface (Figure 1c). A stochastic jump diffusion (SJD) process is used to describe movement of sediment particles in open channel flows.
The stochastic jump diffusion particle‐tracking model (SJD‐PTM) is governed by the stochastic differential equation (SDE). The SDE consists of three main terms including a mean drift motion term, a Wiener process representing random turbulent motion, and a Poisson process.A stochastic multivariate framework was utilized to characterize the random properties associated with discrete sediment particle movement in an open channel flow.
Difficulties in modeling sediment transport with a high degree of accuracy are mainly attributed to the complexity associated with flow randomness and interactions between the flow.
