Alluvia is formed from particles such as gravel, sand, silt and/or clay deposited by physical processes in river channels or on floodplains. Alluvia can contain one or more unconfined, unconsolidated sedimentary aquifers, where groundwater is stored and transmitted through intergranular voids between gravel and sand particles.
