Abstract. The glacier coverage in the Caucasus Mountains underwent considerable changes during last decades. In some regions, observed reduction area is comparable to those European Alps and extent of supra-glacial debris increased on many glaciers. Only a few glaciers are monitored regular basis, while for most areas no continuous field measurements available. this study, regional differences conditions melt with special focus covered tongues well-studied Adyl-su basin northern slope...
.Melt rates of glacier surfaces are strongly influenced by the existence a debris cover. Dependent on thickness and other physical parameters, layer can enhance or reduce ablation as compared to bare ice conditions. Supraglacial moraines appear very frequently Central Asian glaciers, greatly affecting water yield from these high mountain regions. In summer 2005, network 22 stakes was drilled into locations with varying thicknesses southern Inylchek Glacier in central Tian Shan. Mean varied...
Abstract. Glacier mass loss is among the clearest indicators of atmospheric warming. The observation these changes one major objectives international climate monitoring strategy developed by Global Climate Observing System (GCOS). Long-term glacier balance measurements are furthermore basis for calibrating and validating models simulating future runoff glacierised catchments. This essential Central Asia, which driest continental regions Northern Hemisphere. In highly populated regions, water...
A conceptual precipitation–runoff model was applied in five glacierized catchments Central Asia. The model, which first developed and the Alps, works on a daily time step yields good results more continental climate of Tien Shan mountains for present-day conditions. Runoff scenarios different climates (doubling CO2) glacierization conditions predict an increased flood risk as stage complex picture after complete glacier loss: higher discharge during spring due to earlier intense snowmelt is...
Impacts of projected climate and glacier change on river discharge in five glacierized catchments the northern Tien Shan, Kazakhstan are investigated using a conceptual hydrological model HBV-ETH. Regional PRECIS driven by four different GCM-scenario combinations (HadGEM2.6, HadGEM8.5, A1B HadCM3Q0 ECHAM5) is used to develop projections. Future changes glaciation assessed Blatter–Pattyn type higher-order 3D coupled ice flow mass balance model. All scenarios show statistically significant...
Abstract A photogrammetric survey in 1998 formed the basis for compiling a map of Tuyuksu glacier region northern Tien Shan, Central Asia. Comparison with from 1958 enables calculation change volume over 40 years. The results are compared direct annual measurements carried out continuously since 1956. shows mass balance –12.6 mw.e. geodetic method and –16.8 m glaciological measurements. In view high accuracy maps, discrepancy can be explained mainly by deficiencies Application...
.The Inylchek glacier system in Central Tian Shan, Kyrgyzstan, comprises a large glacier‐dammed lake which usually drains once year through subglacial drainage system. Detailed GPS measurements on the ice dam and analysis of Aster scenes from several subsequent years provide insight into post‐drainage response changed dynamic conditions. We demonstrate that during high water levels part is afloat, lifting surface up to almost 20 m central region. During this phase extensive flotation strong...
Five small glaciers in the Bavarian Alps have been surveyed repeatedly since late 19th century. This enables calculation of geodetic glacier mass balances, which are known to be key indicators for climate fluctuations. In this paper, record is extended by analysis additional historical maps and a new survey surfaces 2009/2010. After 1960s 1970s, when positive balances could observed, experienced severe losses, consistent with observations from vast majority mountain worldwide. Although show...
The frequency of glacier lake outbursts floods (GLOFs) is likely to increase with the ongoing retreat, which produces new glacial lakes and enlarges existing ones. Here, we simulate outburst a potentially dangerous in Bhutan by applying hydrodynamic modelling. Although volume known, several parameters connected dam breach routing flood are rough estimates or assumptions, introduce uncertainties results. For this reason, create an ensemble nine scenarios. simulation magnitude timing possible...
Abstract Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice. Most recently, Franz Josef Glacier has entered into a phase strong retreat and downwasting, with increasing emergence debris surface in zone. Previously at Glacier, melt only been measured During February 2012, network 11 stakes was drilled locations varying thickness lower glacier. Mean over 9 days varied range 1.2–10.1 cm d−1,...
The heavily debris-covered Inylchek glaciers in the central Tian Shan are largest glacier system Tarim catchment. It is assumed that almost 50% of discharge River provided by glaciers. For this reason, climatic changes, and thus changes mass balance high impact for whole region. In study, a conceptual hydrological model able to incorporate from areas presented. To simulate melt subsequent runoff past (1970/1971–1999/2000) future (2070/2071–2099/2100), meteorological input data were generated...
Abstract. Glaciers are important water storages on a seasonal and long-term time scale. Where high mountains surrounded by arid lowlands, glacier runoff is an source of during the growing season. This situation can be found in Altay Southern Siberia, where recent glacierization >700 km2 subject to continuous mass loss, even though shrinking comparably slow. The retreat accompanied extension supra-glacial moraine, which itself strongly influences ablation rates. To quantify these effects,...
We developed a spatially distributed conceptual melt and runoff model able to cope with debris covered glacier parts. Subdebris was calculated based on empirical equations derived from field observations. The applied at the Inylchek glaciers. While Southern flows directly into River, Northern is blocked by forms Lake Merzbacher. This lake drained frequently outburst floods. To calibrate model, multi-algorithm, genetically adaptive multi-objective method (AMALGAM) used. Daily observations...
