For a fluid to begin transporting sediment that is currently at rest on a surface, the boundary (or bed) shear stress exerted by the fluid must exceed the critical shear stress for the initiation of motion of grains at the bed. This basic criterion for the initiation of motion can be written as: . WebStreams are the most important agents of erosion and transportation of sediments on the earth’s surface.

Grains transported by ice, unlike those transported by water, are not sorted by size (though streams of meltwater may sort and transport the sediment after deposition).

WebThe suspended load is generally made up of lighter‐weight, finer‐grained particles such as silt and clay. Most of the sediment in a stream is carried as suspended load.
