The Schneealpe karst massif of Triassic limestones and dolomites with the altitude up to 1800ma.s.l., situated 100km SW of Vienna in Kalkalpen, is the main drinking water resource for the city. The catchment area of about 23km 2 is drained by two springs: the Wasseralmquelle (196l/s) and the Siebenquellen (310l/s). This karstic aquifer is approximated by two interconnected parallel flow systems...
Isotopic variations in melting snow are poorly understood. We made weekly measurements at the Central Sierra Snow Laboratory, California, of snow temperature, density, water equivalent and liquid water volume to examine how physical changes within the snowpack govern meltwater δ 18 O. Snowpack samples were extracted at 0.1m intervals from ground level to the top of the snowpack profile...
