Deposit Modelling and Archaeology, Guidance for Mapping Buried Deposits, published by Historic England on 31 January 2020, defines colluvium as: ‘Material moved naturally on slopes by a combination of gravitational processes (mass movement) and hillwash. The sediments are usually locally derived; in the archaeological record, their development has often been exacerbated by human activity.’

Geoarchaeology, Using Earth Sciences to Understand the Archaeological Record, published by Historic England in 2015, defines colluvium as: ‘…soil or sediment material that accumulates at the bottom of a slope. Colluvium can be several metres deep, and is usually poorly sorted with either weak, or no stratification.’
