Alluvium (from Latin alluvius, from alluere ' to wash against ') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings.

The sediment that makes up alluvial deposits is referred to as alluvium. The term alluvial is often used to describe sediments that are deposited beyond the normal flow path or banks of a river, such as floodplains and deltas.

Alluvium, material deposited by rivers. It is usually most extensively developed in the lower part of the course of a river, forming floodplains and deltas, but may be deposited at any point where the river overflows its banks or where the velocity of a river is checked—for example, where it runs

Aug 28, 2017 · Alluvium is the term used to describe sediments deposited by rivers. Rivers constantly carry sedimentary materials along their course, usually the result of erosion. The majority of these materials are picked up in areas of the river where the water runs very quickly and has more force.

The meaning of ALLUVIUM is clay, silt, sand, gravel, or similar detrital material deposited by running water.

Alluvium is loose earth which sits on top of consolidated sediment (~ rock). It usually consists of loose gravel and clay. Where people live, it is usually covered with "made ground". That is what we call pavements, buildings, and roads. They are the most obvious examples of made ground.

The sediments, known as alluvium, can range from clay-sized particles less than 0.002 mm (.00008 in) in diameter to boulders, which are defined as rocks greater than 256 mm (10 in) in diameter, depending on their source and the sediment …

Alluvium (from the Latin alluvius, from alluere, meaning "to wash against") is soil or sediment deposited by a river or other running water. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay , and larger particles of sand and gravel .

Alluvium (from the Latin word for “flood”) is a more or less stratified deposit of gravel, sand, silt, clay, or other debris, moved by streams from higher to lower ground (Howell et al., 1957). It is usually distinguished by its mode of deposition from lacustrine and marine sediments, deposited, respectively, by the waters of lakes and seas ...

Alluvium comprises clay, silt and sand (in some definitions gravel is included) and derives from the erosion of rocks and soils in the upper reaches of river basins. The mineral characteristics of the alluvium thus reflect its origins.
