Publikováno v: Water; Volume 15; Issue 3; Pages: 397

On the edge of sedimentary basins, karst aquifers can be fed by several water sources from both autogenic and allogenic recharge. In some cases, assessing water origins can be hard and cause some difficulties for water resource management. The main g

Publikováno v: Collection EDYTEM. Cahiers de géographie. 19:235-242

Karst aquifers are heterogeneous and complex media. Their hydraulic conditions are highly variable in space and time. Particles tranfer in these aquifers give some informations on transport properties and groundwater dynamics. The aim of this paper i
