the
interior of the ice sheet is somewhat too dry (Fig. 9b). By average a mean negative precipitation
bias of 0.16myr−1 results which equals 43% of the mean from Burgess et al. (2010) (Table 2).
6 Bias Correction and Future Scenario Runs
After having specified a number of biases in the RCM output the model runs were repeated
with bias-corrected RCM data.

AMF series for a given duration D from different sites, the estimation is made individually for
each site i by pooling AMF series for different durations D (see Crochet, 2012c). The index
flood µi(D), is modeled at each site i as a continuous function of D, as follows:

The hydrological simulations were performed with the Wa-
tershed Simulation and Forecasting System (WSFS) developed
and operated in the Finnish Environment Institute (Vehviläinen
et al., 2005). The WSFS is used in Finland for operational hydrolog-
ical forecasting and flood warnings (www.environment.fi/water-
forecast/), regulation planning and research purposes

increasing number of backcountry travellers in Iceland during
winter time. The number of human-triggered avalanches recorded

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).
