| Zusammenfassung |
| An energy balance method and remote-sensing data were used to simulate snow
distribution and melt in an alpine watershed in northwestern China within a
complete snow accumulation-melt period. The spatial energy budgets were
simulated using meteorological observations and a digital elevation model of
the watershed. A linear interpolation method was used to estimate the daily
snow cover area under cloudy conditions, using Moderate Resolution Imaging
Spectroradiometer (MODIS) data. Hourly snow distribution and melt, snow cover
extent and daily discharge were included in the simulated results. The root
mean square error between the measured snow-water equivalent samplings and
the simulated results is 3.2 cm. The Nash and Sutcliffe efficiency statistic
(NSE) between the measured and simulated discharges is 0.673, and the volume
difference (Dv) is 3.9 %. Using the method introduced in this article,
modelling spatial snow distribution and melt runoff will become relatively
convenient. |
