WebCoarse-grained soil. According to the uniform soil classification system, the soil is coarse-grained if more than 50% of the soil remains in a sieve of 0.075 mm. Coarse-grained soil is further divided into two types: Gravel (G) – If more than 50% of the coarse particles are retained on the 4.75mm sieve, it is known as Gravel. WebHOST Project. The Hydrology of Soil Types project used these national soil maps to reclassify UK soils according to 29 different hydrological performance classes. The classification system is shown in the table below. Where high resolution maps including the catchment are not available, the HOST class can be estimated using the above table.
