That fluviokarst is 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]. synonyms: (french.) fluviokarst; (german.) fluviokarst; (greek.) fluviokarst; (italian.) fluviocarsimo; (spanish.) fluviokarst; (turkish.) akarsu karsti; (yugoslavian.) fluviokrs, fluviokras, fluviokarst.?

Modeling complex flow in a karst aquifer
Abstract:
Carbonate aquifers typically have complex groundwater flow patterns that result from depositional heterogeneities and post-lithification fracturing and karstification. Various sources of information may be used to build a conceptual understanding of flow in the system, including drilling data, well tests, geophysical surveys, tracer tests, and spring gaging. These data were assembled to model flow numerically in Germany's Malm Formation, at a site where water disappears from the beds of ephemeral stream valleys, flows through conduit systems, and discharges to springs along surface water features. Modeling was performed by using a finite-difference approach, with drain networks, representing the conduit component of flow, laced throughout the porous medium along paths inferred on the basis of site data. This approach represents an improvement over other karst models that attempt to represent a conduit by a single, specialized model node at the spring location or by assigning a computationally problematic extremely high permeability to a zone. By handling the conduit portion of this mixed-flow system with drains, a realistic, interpretive flow model was created for this intricate aquifer
