Alluvial soil is found in the river deltas of the eastern coast. For example, a soil with 30% clay, 50% sand, and 20% silt is called a sandy clay loam. Its water holding capacity is very high. This soil has very good water storage qualities and makes it hard for moisture and air to penetrate into it.
