Response of snow hydrological processes to a changing climate during 1961 to 2016 in the headwater of Irtysh River Basin, Chinese Altai Mountains

With changing climatic conditions andsnow cover regime, regional hydrological cycle for asnowy basin will change and further available surfacewater resources will be redistributed. Assessing snowmeltwater effect on laxnoff is the key to water safety,under climate warming and fast social-economicdeveloping status. In this study, stable isotopictechnology was utilized to analyze the snow meltwatereffect on regional hydrological processes, and todeclare the response of snow hydrology to climatechange and snow cover regime, together with long-term meteorological and hydrological observations, inthe headwater of Irtysh River, Chinese AltaiMountains during 1961-2015.
