Alluvial soils are mainly associated with river floodplains. Alluvial soils are hard to define satisfactorily as they are developed on fluvial, lacustrine or marine deposits. They are also cloured into light and dark soils. Their respective colours are due largely to the relative abundance of organic matter in the surface soil.
