Karst System Conceptual Models Based on the Aquifer Recharge
摘要
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 are by rain or snow melt, directly recharging the aquifer, whereas the secondary inputs are the surface runoff waters continuously recharging the aquifer. Taking into account the recharge of the system, four different basic conceptual models can be distinguished: systems with primary inputs prevailing, systems with primary and secondary inputs, systems with secondary inputs prevailing, systems with prevailing inputs by decanting. Monitoring with multiparameter probes (continuous acquisition of water levels/discharge, temperature and electrical conductivity of spring waters) allows to highlight the different recharge models.
