Karst hydrogeology

The weathered skin of karst that stores and routes water

The epikarst is the uppermost layer of a karst rock mass, the zone just below the soil where the bedrock is most intensely fissured and dissolved, so it is far more porous and permeable than the rock beneath. It acts as a shallow reservoir that catches infiltrating rain, holds it, and then feeds it downward in concentrated trickles that nourish the vadose zone and the speleothems below. Williams's 2008 review sets out its role in karst and cave hydrogeology, and Ford and Williams place it in the broader aquifer. The referent is a hydrologically distinct weathered layer at the top of a karst system.[1][2]

Unit
The fissured near-surface karst layer and the water it stores and transmits
Recovery means
Not applicable
Measured by
Characterised by its storage capacity and permeability, inferred from drip-rate monitoring, geophysics, and infiltration response
