Karst aquifers represent an important groundwater resource world-wide. They are highly vulnerable to contamination due to fast transport through the system and limited attenuation of contaminants. The two main hydrogeological approaches developed for studying flow and transport are: inference of the system structure from karst spring hydrographs and chemographs; numerical modelling of flow and...

Geometry and hydraulic parameters of karst aquifers : a hydrodynamic modeling approach

Kovács, Attila ; Perrochet, Pierre (Dir.) ; Jeannin, Pierre-Yves (Codir.)

Thèse de doctorat : Université de Neuchâtel : 2003 ; 1724.

This thesis presents a method for characterizing flow systems in karst aquifers by acquiring quantitative information about the geometric and hydraulic parameters of a karst conduit network from spring hydrograph analysis. The investigation method applied consisted of constructing simple conceptual models of karst systems, and deducing analytical formulae describing the connection between aquifer...
