O - Overlying layer factor
Description
This layer considers the nature and thickness of soils, subsoils, unsaturated zone confinement. The lowest values correspond to areas of karst aquifer with no overlying subsoil and the water table is at or near the surface. The highest values are for non karst rocks overlain by thick impermeable subsoils with a deep water table. The biggest influencing factor here was the presence and thickness of clay subsoil
