HOST is a hydrologically-based classification of the soils of the UK. 29 soil classes are grouped by hydrological properties, particularly their ability to transmit water both vertically and horizontally. The dominant HOST class and a percentage breakdown by HOST classes are available for each 1km square, with no further information on spatial distribution. The area of lake or reservoir is also held. HOST is used to estimate the Baseflow Index (BFI) and standard percentage runoff, from which low flow and flood statistics can be generated for ungauged catchments.
