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.
