    Analysis of temporal and spatial variations in hydrometeorological elements in the Yarkant River Basin, China

    Wei, Ren-juan ; Peng, Liang ; Liang, Chuan ; Haemmig, Christoph ; Huss, Matthias ; Mu, Zhen-xia ; He, Ying

    In: Journal of Water and Climate Change, 2019, vol. 10, no. 1, p. 167–180

    Yarkant River is a tributary of Tarim River in China, and the basin lacks observational data. To investigate past climatic variations and predict future climate changes, precipitation, air temperature and runoff data from Kaqun hydrological station are analysed at monthly and seasonal scales using detrended fluctuation analysis (DFA). Results show that DFA scaling exponents of monthly...

    Surge dynamics and lake outbursts of Kyagar Glacier, Karakoram

    Round, Vanessa ; Leinss, Silvan ; Huss, Matthias ; Haemmig, Christoph ; Hajnsek, Irena

    In: The Cryosphere, 2017, vol. 11, no. 2, p. 723–739

    The recent surge cycle of Kyagar Glacier, in the Chinese Karakoram, caused formation of an ice-dammed lake and subsequent glacial lake outburst floods (GLOFs) exceeding 40 million m³ in 2015 and 2016. GLOFs from Kyagar Glacier reached double this size in 2002 and earlier, but the role of glacier surging in GLOF formation was previously unrecognised. We present an integrative analysis of...

    Hazard assessment of glacial lake outburst floods from Kyagar glacier, Karakoram mountains, China

    Haemmig, Christoph ; Huss, Matthias ; Keusen, Hansrudolf ; Hess, Josef ; Wegmüller, Urs ; Ao, Zhigang ; Kulubayi, Wubuli

    In: Annals of Glaciology, 2014, vol. 55, no. 66, p. 34–44

    Kyagar glacier is located in the Chinese Karakoram mountains. The glacier tongue entirely blocks the riverbed in the upper Shaksgam valley and impounds a glacial lake, which was the source of several violent and disastrous glacial lake outburst floods (GLOFs). A GLOF early warning system was implemented between 2011 and 2013. We present an integrative analysis of the hazard potential of Kyagar...
