Abstract The Gunt River catchment in the Central Pamirs is a representative of the headwater catchments of  the
Aral Sea Basin. It covers 14,000 km2 , spanning altitudes between 2000 and 6700 m a.s.l. In a
monitoring network, water samples were taken at 30 sampling points every month and analysed for the
stable water isotopes (18 O and 2 H). Our first results show δ2 H values in the range from −131.2
to −94.9 ‰ and δ18 O values from −18.0 to −14.0 ‰. The stable isotope patterns in the catchment
seem to follow a systematic way, dominated by an altitude effect with a mean ßδ2 H = −3.6 ‰/100 m.
The observed seasonal variations can be explained by geographical aspects such as the influence of
different wind systems as well as melting processes.
