Multi-tracer approach for characterizing rock glacier outflow
The present study used a multi-tracer approach (water stable isotopes, electrical conductivity (EC), and major, minor, and trace elements) to identify the impact of rock glacier outflow on water quality. Springs and streams/creeks fed by rock-glaciers were selected in the Upper Sulden and Zay catchm...
