Hydrology of soil types data product

In this Hydrology of Soil Types (HOST) dataset, 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. 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.
