Abstract

Karst systems fed by an allogenic inflow often show a complex network of interacting conduits that effects groundwater flow and pollutant transport. The combined evaluation of multi-tracer experiments performed at different flow conditions provide information about the hydrodynamic functioning of the karst network. Building on this, a conceptual model to quantify groundwater flow and mass transport has been developed and is presented in this study using the example of the Tanneben Massif, Austria. Within the model, groundwater flow is subdivided into several flow-paths with discrete flow velocity and capacity. As a consequence, model results reveal a dampen but also extended karst response to storm events. Upon exceeding the flow capacity, backwater accumulates at the inflow causing a prolongation of high discharge into the system. Additionally, adjacent karst systems are affected by the activation of interconnecting flow paths at high flow conditions.
