Alluvial deposit geological feature Britannica

Alluvial deposit, Material deposited by rivers. It consists of silt, sand, clay, and gravel, as well as much organic matter. Alluvial deposits are usually most extensive in the lower part of a river’s course, forming floodplains and deltas, but they may form at any point where the river overflows Alluvial deposit, Material deposited by

The usefulness of the alluvial deposit as an earth construc-tion material was analysed after their structure had been destroyed and compacted with a Proctor apparatus. In cases of samples characterized by different water content and soil particle density, the analysis of changes in terms of cohesion and the internal friction angle proved that these parameters are influenced by the soil phase ...

Alluvial Deposit - an overview ScienceDirect Topics

1.5.1.1 Alluvial deposits (river beds) The soils deposited in riverbeds are known as alluvial deposits. Some textbooks use the term, “Fluvial deposits” for the same thing. The size of particles deposited in riverbeds depends on the speed of flow. If the river flow is strong, only large cobble-type material can deposit. 1.5.1.2 Marine deposits

The presence of alluvial deposits may mean that the ground conditions are poor and so can require the construction of a raft foundation, or deep pile foundations. In these conditions, strip or pad foundations would require significant excavation.

Near Banff, the floodplain of the Deveron is underlain by 2 to 3 m of silt overlying 7 to 15 m of alluvial deposits including sand and gravel. The floodplain of the Ythan is underlain by 4 to 6 m of gravel downstream of Methlick, whereas thicknesses of between 7 and 10 m of alluvial gravel are common in the Dee valley. Alluvial gravels of the Don typically range between 3 and 5 m in thickness ...

How are alluvial placer deposits formed?

Alluvial placers are formed by the deposition of dense particles at a site where water velocity remains below that required to transport them further. To form a placer deposit, the particles desired must show a marked density contrast with the gangue material, which is able to be transported away from the trap site.
