spring, vauclusian

   ; rising, vauclusian
   1. A type of rising or spring where direct drainage from the phreas flows up a flooded cave passage under pressure to emerge in daylight. The term is best applied where water rises from a vertical or very steep bedrock passage. Such risings are named after the Fontaine de Vaucluse in southern France. The River Sorgue rises from the Fontaine with a mean flow of 26 cubic meters per second. Its upper part is steeply inclined, but a depth it is vertical. A diver has reached a depth of –200m, and a robot reached –243m, below which the flooded shaft continues [9].
   2. Large karst spring (name by Fournet, after la Sorgue en Vaucluse, France) characterized by a stream surging up as from a siphon. Also applied to karst springs with artesian characteristics [20].
   3. A large spring or exsurgence of an underground river, generally from limestone, that varies greatly in output and is impenetrable except with diving apparatus [10].
