Eroded material that gets carried downstream by the current of the stream or river. Alluvial deposits are areas in streams or rivers where alluvium does not continue flowing downstream, thus forming a deposit.
An unconsolidated terrestrial sediment composed of sorted or unsorted sand, gravel, and clay deposited during comparatively recent geologic time by a stream or river. Alluvial deposits include mid channel bar, point bar, floodplain deposits, alluvial fans, and fluvial terrace.
The deposits of matter such as clay, silt, sand, clay, mud, or soil which are deposited on riparian land in the process of alluvion.If you have purchased a foreclosed property that has alluvium, you are fortunate.You are in the process of gaining land and you likely are located near a river, which is a key selling point when it is time to resell your property.
Sediment (mud, sand, and gravel) laid down by flowing water. The largest particles (sand and gravel) tend to accumulate within the channel itself. Particles of clay, silt, and fine sand are small enough to be suspended in flowing water. When the stream overflows its banks, these particles can be distributed across the valley floor. These overbank or flood deposits are the most common contexts in which buried archaeological sites are found. Stream valley floors are underlain by deposits of alluvium and often contain buried archaeological sites.
general term for sediments of gravel, sand, silt, clay, or other particulate rock material deposited by flowing water, usually in the beds of rivers and streams, on a flood plain, on a delta, or at the base of a mountain.
A sediment deposited by streams and varying widely in particle size. The stones and boulders when present are round or sub-rounded. Some of the most fertile soils are derived from alluvium of medium or fine texture.
deposits of clay, silt, sand, gravel, or other particulate material that has been deposited by a stream or other body of running water in a streambed, on a flood plain, on a delta, or at the base of a mountain.
A general term for unconsolidated material (e.g. clay, silt, sand, gravel) deposited from running water. Often a sorted or semi-sorted sediment in the bed of a stream or on its floodplain or delta. The deposit may be in the form of an alluvial fan.
Alluvium (from the Latin, alluvius, from alluere, "to wash against") is soil or sediments 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.
