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.

the discharge in Skaftá and the
temperature of the flood water close to the glacier margin were measured. The dis-
charge from the subglacial lake during the jökulhlaup was calculated using a hypso-
metric curve for the subglacial lake, estimated from the form of the surface cauldron
after jökulhlaups. The maximum outflow from the lake during the jökulhlaup is esti-
mated as 123 m3 s 1 while

To distinguish between rain and snow, the volume is com-
pared to the water equivalent but the volume of snow is ten times larger.

Using the information about the changes of the backscatter signal, water equivalent and temper-
ature the Vaisala Present Weather Detector can give information about the type of precipitation.
