were carried out to obtain the flow and
sliding parameters for Hoffellsjökull that resulted in a good
simulation of the observed 20th century evolution of the
glacier geometry. The obtained values for the rate factor
and the sliding parameter are A= 4.6× 10−15 s−1 kPa−
3 and
C = 10× 10−15 m a−1 Pa−
3, respectively.
