Using tracers techniques to investigate hydrosystems and to improve rainfall-runoff modelling

Monitoring of water quantity and chemistry and additional tracer experiments were carried out in the meso-scale (40 km2) mountainous Brugga basin, south-western Germany, since 1994. A thorough insight was gained into the runoff generation processes. The main source areas of runoff components, flow pathways and mean residence times of the runoff components were determined by using different tracer methods.
