FLUVIOKARST

   1. A karst landscape where the dominant landforms are valleys cut by surface rivers. Such original surface flow may relate either to low initial permeability before caves (and hence underground drains) had developed, or to reduced permeability due to ground freezing in a periglacial environment. In both cases the valleys become dry as karst development improves underground drainage [9].

   2. Mixed terranes characterized by both shallow karst and erosional landscape [20].

   3. A predominantly karst landscape in which there is much evidence of past or present fluvial activity [10].
