and summer balance (bs) have been carried out at
Storbreen since 1949. Here we apply a simple mass
balance model to study the climate sensitivity and
to reconstruct the mass balance series prior to 1949.
The model is calibrated and validated with data
from an automatic weather station (AWS) operating
in the ablation zone of Storbreen since 2001. Re-
gression analysis revealed that bw was best mod

whereas NVE has carried out the further processing. The collected
data are used to calculate geodetic mass balance and are compared with mass balance
measured by the direct method where available. The new laser data combined with old
surveys are thus important for an independent validation of the direct field method. Here we
present the methods used for assessing the geodetic mass balance

with the same method used to estimate
qR(D;T ), but instead of pooling 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.
The index flood, µi(D), is modelled at each site i as a continuous function of D, as follows:

µi(D) =
µi
1+(D=Di)li

where µi, Di and li are basin dependent parameters

The work of the Hydropower-Hydrology group of CES is carried out by a network of scientists mainly from the national institutes. Thus a wide range of aspects of hydropower and natural conditions are covered, from the glaciated basins
