1950–2100 and incorporates Greenland at a resolution of approx. 25km. Ahlstrøm et al. (2008a)
have analyzed its bias in air temperature and precipitation over the ice sheet at Paakitsôq,
Aðalgeirsdóttir et al. (2009) compared those two parameters to a larger number of weather
stations over Greenland.

an over-
all picture (67 sites of varying runoff area sizes) of the changes in
floods by 2010–2039 and 2070–2099 using conceptual hydrologi-
cal modelling and several climate scenarios and (2) estimating
the consequent changes in flood inundation at four selected settle-
ments using 2D hydraulic modelling. A further goal is (3) to outline
climate change effects regionally as well as in different types

is located in the interior of the region and is 50% glaciated. For sake
of simplicity, it was decided to form one single candidate region with all catchments, according
to the cluster analysis. Table 2 presents the homogeneous groups of catchments obtained with
the ROI technique, associated to each target catchment. The catchments are ordered from most
similar to least similar.

-based and 10 based on IPCC GCM
simulations. The choice of the GCM models was based on their SAT
performance for the present-day climate near Iceland as mentioned above.
2. For GCM-based scenarios, temperature change in the highland interior of
Iceland, where the large ice caps are located, were increased by 25% based on
the results of RCM downscaling (Nawri & Björnsson, 2010).

past observations, it is used to simulate the future response of
the glacier during the 21st century. The mass balance model
was forced with an ensemble of temperature and precipita-
tion scenarios derived from 10 global and 3 regional climate
model simulations using the A1B emission scenario. If the
average climate of 2000–2009 is maintained into the future,

Kjøllmoenet al. 2007).Storbreen is located just east of the main waterdivide between east and west in southern Norwayand receives precipitation from both directions(Liestøl 1967). The glacier is part of an east–west
mass balance transect in southern Norway where
mass turnover is largest near the western coast anddecreases towards the drier interior (Andreassen etal. 2005). Storbreen is in this respect
