%X An energy balance method and remote-sensing data were used to simulate snowdistribution and melt in an alpine watershed in northwestern China within acomplete snow accumulation-melt period. The spatial energy budgets weresimulated using meteorological observations and a digital elevation model ofthe watershed. A linear interpolation method was used to estimate the dailysnow cover area under cloudy conditions, using Moderate Resolution ImagingSpectroradiometer (MODIS) data. Hourly snow distribution and melt, snow coverextent and daily discharge were included in the simulated results. The rootmean square error between the measured snow-water equivalent samplings andthe simulated results is 3.2 cm. The Nash and Sutcliffe efficiency statistic(NSE) between the measured and simulated discharges is 0.673, and the volumedifference (Dv) is 3.9 %. Using the method introduced in this article,modelling spatial snow distribution and melt runoff will become relativelyconvenient.
