Abstract

<p>Most of Central Asia is dry region and people are highly dependent on water from glaciers at the upper basins, which is heavily affected by global warming. In order to evaluate its effects on water supply, a hydrological model that can reproduce seasonality of melting in high mountain glaciers is required. Land surface model SiBUC dose not consider glacier as a land surface condition and previous study shows that snow melts earlier than real. In this study, using in-situ data in Bordu glacier in Kyrgyz Republic we considered the existence of ice in heat budget equations and snow aging in SiBUC. In research field, the result of calculation of snow water equivalent by conventional SiBUC shows that calculated snow melts one month earlier than observed snow does. On the other hand, snowmelt delayed for two weeks by SiBUC considering glaciers.</p>
