A flow of water above ground level that occurs where the water-table intercepts the ground surface. Where the flow from a spring is not distinct (i.e. it does not give rise to obvious trickles) but tends to be somewhat dispersed, the flow is more correctly termed a ‘seep’. The reappearance of surface water that had been diverted underground in a karst region is a type of spring known as a ‘resurgence’. A major variety is the ‘Vauclusian spring’, named after the Fontaine de Vaucluse, southern France, and descriptive of the upward emergence of an underground river from a flooded solution channel.
