δ 18 O/δ 2 H and 87 Sr/ 86 Sr in supporting understanding a complex karstic system linked to surface water -The Loiret system, France

The project CENARI-O aimed at improving knowledge on groundwater-surface water exchanges in a complex karstic area modified by hydraulic infrastructures combining various tools. The results obtained using δ18O/ δ2H and 87Sr/86Sr were compared to in situ conductivity and temperature measurements in order to complete the information. The Loiret River is mainly fed by groundwater along its flow path. This very particular flow system is more complex and various tools were needed to improve surface-groundwater knowledge.
