Abstract: Environmental isotope studies can be used as a tool to get better insight into snow hydrology. The isotope labelling of the snowcover of its single layers, of the precipitations, and of the discharge concerning its origin gives possibilities to study the mass exchange between meltwater and snowcover and between the individual snow layers. Measurements of isotope contents have also be used to estimate the net evaporation rate of a snowcover during the ablation period, the fractions of groundwater and surface water discharge from catchment areas with a temporary snowcover, the fraction of snow meltwater and ice meltwater in a glacier discharge. In arctic areas the environmental isotopes enable to date firn and glacier ice cores and the long-term conservation of seasonal variations of isotope concentrations in the glacier ice permits a much better identification of annual ice layers than is possible by conventional strati-graphic methods.

TL;DR: A preliminary study based on environmental isotopes, of tritium and oxygen-18, shows that most of the seepage water is probably derived from local groundwater.
