Zusammenfassung |
A major proportion of flow in the Indus River is contributed by its snow-
and glacier-fed river catchments situated in the Himalaya, Karakoram and
Hindukush ranges. It is therefore essential to understand the cryosphere
dynamics in this area for water resource management. The MODIS MOD10A2
remote-sensing database of snow cover products from March 2000 to December 2009 was selected to analyse the snow cover changes in the Hunza River basin
(the snow- and glacier-fed sub-catchment of the Indus River). A database of
daily flows for the Hunza River at Dainyor Bridge over a period of 40 yr
and climate data (precipitation and temperature) for 10 yr from three
meteorological stations within the catchment was made available to
investigate the hydrological regime in the area. Analysis of remotely sensed
cryosphere (snow and ice cover) data during the last decade (2000–2009)
suggest a rather slight expansion of cryosphere in the area in contrast to
most of the regions in the world where glaciers are melting rapidly. This
increase in snow cover may be the result of an increase in winter
precipitation caused by westerly circulation. The impact of global warming
is not effective because a large part of the basin area lies under high
altitudes where the temperature remains negative throughout most of the
year. |
