Suspended load [1]
This article needs additional citations for verification. The suspended load of a flow of fluid, such as a river, is the portion of its sediment uplifted by the fluid’s flow in the process of sediment transportation
The suspended load is one of the three layers of the fluvial sediment transportation system. The bed load consists of the larger sediment which is transported by saltation, rolling, and dragging on the riverbed
The wash load is uppermost layer which consist of the smallest sediment that can be seen with the naked eye; however, the wash load gets easily mixed with suspended load during transportation due to the very similar process. The wash load never touches the bed even outside of a current.

media, water (running water), ice (glaciers), and air (wind). Running water transports the majority of sediments and is responsible for craving most of the landforms (mountains, valleys, etc.)

Sediment Transport and Deposition [3]
Sediment refers to the conglomerate of materials, organic and inorganic, that can be carried away by water, wind or ice 3. While the term is often used to indicate soil-based, mineral matter (e.g
Most mineral sediment comes from erosion and weathering, while organic sediment is typically detritus and decomposing material such as algae 4.. These particulates are typically small, with clay defined as particles less than 0.00195 mm in diameter, and coarse sand reaching up only to 1.5 mm in diameter 5
Sediment is a naturally occurring element in many bodies of water, though it can be influenced by anthropogenic factors 8.. In an aquatic environment, sediment can either be suspended (floating in the water column) or bedded (settled on the bottom of a body of water)
Stream Sediment Transport [4]
The animation shows the transport of sediment under low flow and high flow conditions in a stream. Most of the sediment transport occurs in high flow conditions
S&WCE: Lesson 20 Sediment Transport and Measurements [5]
Transport of particles in flowing water takes place through sliding, rolling, saltation and suspension. Different mechanisms of transport are discussed below.
Sliding particles remain in continuous contact with the bed, merely tilting to and fro as they move. Rolling grains also remain in continuous contact with the bed, whereas saltation grains ‘jump’ along the bed in a series of low trajectories
The suspended load consists of particles in suspension. These particles follow long and irregular paths within the water and seldom come in contact with the bed until they are deposited when the flow slackens
Sediment Transport and Deposition [6]
Sediment transport and deposition are key processes in sedimentology that govern the formation of sedimentary rocks. The movement of sediment can occur through a variety of mechanisms, including wind, water, ice, and gravity
Once sediment is transported, it can be deposited in a wide range of environments, including river channels, lakes, deltas, beaches, and deep marine basins. The depositional environment influences the characteristics of the sediment that is deposited, such as grain size, sorting, and composition.
This knowledge can also be applied to a range of practical applications, such as the management of water resources, the construction of dams and levees, and the prediction and mitigation of geological hazards such as landslides and debris flows.. The agents of sediment transport are the natural forces that move sediments from one location to another
Where Do Mountain Streams Get Most Of Their Load Of Sediment? [7]
Streams transport their load of sediment in three ways: in solution (dissolved load) in suspension (suspended load) or scooting or rolling along the river bottom (bed load).. In rivers deposition occurs along the inside bank of the river bend [This “area” is where water flows slower] while erosion occurs along the outside bank of the bend where the water flows a lot faster.
Suspended load generally consists of fine sand silt and clay size particles although larger particles (coarser sands) may be carried in the lower water column in more intense flows.. On flatter ground streams deposit material on the inside of meanders
When a stream flows onto its floodplain its velocity slows and it deposits much of its load.. When particles are eroded and transported by wind water or ice they become part of the transport medium’s sediment load
Effects of River-Ice Breakup on Sediment Transport and Implications to Stream Environments: A Review [8]
Effects of River-Ice Breakup on Sediment Transport and Implications to Stream Environments: A Review. – Abrasion, gouging, and removal by ice rubble of the upper layer of cantilevered rootmats thereby exposing the bank to subsequent fluvial entrainment of fine-grained material and disruption of the armour pavement of cobbles along the bank toe, with rubble-ice impact observed to be more severe for banks near the upstream tip of an island or bar or where flow directed rubble directly against a bank;
– Increased flow velocity and the removal of armour pavement of cobbles and gravel due to ice congestion in the channel, which could occur because of an ice cover and anchor ice, flow concentration beneath and around an ice jam, and from an ice-jam-release jave. The primary effects of increased shear stress on bank erosion are mobilization of bank toe pavement (most likely due to javes), entrainment of bank material, and undercutting and failure of the vegetated top of bank [10].
– Heavy runs of ice rubble that follow the large ice sheets often result in formation of thick grounded strips along the river banks. Such strips shield the banks from further erosion either by ice abrasion and gouging or by the high-velocity water underneath the moving rubble.
Sediment Load [9]
The majority of a stream’s sediment load is carried in solution (dissolved load) or in suspension. Earth material that has been dissolved into ions and carried in solution is the dissolved load
These ions may react to form new minerals if the proper chemical conditions are encountered during flow. Minerals may also precipitate in trapped pools through evaporation.
For example, a flooding river is muddy and discolored from the large amounts of sediment suspended in the water. The suspended load is generally made up of lighter‐weight, finer‐grained particles such as silt and clay
Stream Processes [10]
Stream velocity is the speed of the water in the stream. Units are distance per time (e.g., meters per second or feet per second)
Hydraulic radius (HR or just R) is the ratio of the cross-sectional area divided by the wetted perimeter. For a hypothetical stream with a rectangular cross sectional shape (a stream with a flat bottom and vertical sides) the cross-sectional area is simply the width multiplied by the depth (W * D)
The greater the cross-sectional area in comparison to the wetted perimeter, the more freely flowing will the stream be because less of the water in the stream is in proximity to the frictional bed. So as hydraulic radius increases so will velocity (all other factors being equal).
13.3 Stream Erosion and Deposition – Physical Geology [11]
As we discussed in Chapter 6, flowing water is a very important mechanism for both erosion and deposition. Water flow in a stream is primarily related to the stream’s gradient, but it is also controlled by the geometry of the stream channel
In fact, the velocity just below the surface is typically a little higher than right at the surface because of friction between the water and the air. On a curved section of a stream, flow is fastest on the outside and slowest on the inside.
During a flood, the water level always rises, so there is more cross-sectional area for the water to flow in; however, as long as a river remains confined to its channel, the velocity of the water flow also increases.. Figure 13.15 shows the nature of sediment transportation in a stream
