dc.description.abstract
The use of groundwater from alluvial aquifers largely affects stream discharge by capturing the stream resources. This affects hydrological processes and riparian biodiversity. In this study, complementary water resources are investigated in an effort to ease human pressure on alluvial systems and, eventually, on stream-aquifer relationships. Discharge and hydrochemical data along a 5 km reach of the Tordera River (NE Spain) provide evidence that groundwater fluxes, associated with a regional hydrogeological system related to the basement fracture network, contribute to alluvial recharge and to stream flow. End-member mixing analysis considering upstream discharge, groundwater flows, and human inputs to the stream as major flow sources shows that regional basement groundwater fluxes are responsible for as much as 20 % of the total discharge, which also explains unexpected rises in stream flow. This suggests a possible new approach to local water resources planning, indicating that conjunctive use might actually be feasible
