Název v původním jazyce

Hydrological characterization and connectivity of proglacial lakes to a stream, Adygine ice-debris complex, northern Tien Shan

Popis výsledku v původním jazyce

In this study, we characterized the glacial meltwater flow through a proglacial area with a focus on proglacial lakes, their hydrological regime and their connection to the stream. The studied lakes - the Adygine ice-debris complex, northern Tien Shan - showed a distinct development throughout an ablation season: at Lake 2, the mean daily water-level fluctuation amplitude increased from 0.07 m to 0.18 m (June, August), then dropped to 0.07 m in September. Glacial meltwater flows through the lakes and further downstream through a rock glacier rather fast, moving at 0.085 m s-1. However, based on the low dye recovery in the stream (0.03%), only a small portion of water was routed efficiently. The complexity of the site&apos;s drainage system was supported by varying isotopic composition of water in the tarns situated on the rock glacier, with Tarn a (δ2H: -36.08%o; δ18O: -6.25%o) being the most enriched and Tarn c (δ2H: 78.68%o; δ18O: 11.9%o) the most depleted in heavy isotopes.
