Assessment of slope stability, soil management or contaminant transport problems usually requires numerous, yet accurate point measurements of permeability. This technical note describes a new method for the rapid field assessment of permeability in near‐surface soils or unconsolidated sediments. The procedure is known as ‘ring permeametry’ and is an ex situ core‐based method giving measurements which can be guaranteed to be stratum‐specific, unlike measurements from some in situ techniques. The potential sources of precision and bias error within the method are quantified and their effect on the uncertainty of permeability estimates is illustrated. © 1997 John Wiley & Sons, Ltd.
