摘要: Mean tracer ages on the Gallusquelle spring (Swabian Alb) were determined with lumped parameter modeling and decrease in following order: H >>Kr >He. Since is part of water molecule it enters a karst system via precipitation, i.e. mean age measure flow through whole system, including unsaturated saturated zone. The Kr H/He are measures time since groundwater recharge arrived at table. Therefore our results indicate long travel zone system.
