Karst system conceptual models based on the aquifer recharge [PDF]

open access: yes
The aquifer recharge heavily affects both the hydrodynamic and the main water chemical-physical parameters. The recharge of the aquifer is mainly linked to primary and/or secondary inputs: the primary inputs (or authigenic) are by rain or snow melt ...
