| Zusammenfassung |
| It has been observed that a majority of glaciers in the Himalayas have been retreating.
In this paper, we show that there are two major factors which
control the advance/retreat of the Himalayan glaciers. They are the slope of the glacier and changes in
the equilibrium line altitude. While it is well known,
that these factors are important, we propose a new way
of combining them and use it to predict retreat.
The functional form of this model has been derived from
numerical simulations using an ice-flow code.
The model has been successfully applied to the movement of eight Himalayan glaciers
during the past 25 years.
It explains why the Gangotri glacier is retreating while Zemu of
nearly the same length is stationary, even if they are subject to
similar environmental changes.
The model has also been applied to a larger set of glaciers in the
Parbati basin, for which retreat based on satellite data is available, though
over a shorter time period. |
