A calibrated approach (standardized questionnaires and
interviews, expert judgment, and reinterpretation of out-
comes by means of relevant literature) was used to com-
pare the state of affairs in water management in the
selected case-studies.
Adaptive and integrated water management
Given the expected increase of climate-related extreme
events, water governance capabilities

for the largest ones. For these catchments, the index flood model is ex-
trapolated far beyond the range of characteristics for which it was developed and the estimation
of µi(D) may not be valid. This is in line with Crochet (2012a,b). This is the case in Region 1 for
catchment vhm200, for which the index flood is usually strongly understimated. This catchment
is by far the largest and much larger than

the com-
plexity of the hydrological processes through modelling, but its application is usually limited to
the short-range. Although the results demonstrated a great potential for this method, its success-
ful application in real-time will strongly depend on the quality and availability of streamflow
observations, which can be poor or simply missing during periods of variable durations, e.g

leading to the selection of the Peak-over-
Threshold method as it shows more similarities when applied to both sets of data. Intensity–
duration–frequency (IDF) graphs are presented for each station, based on simulated precipitation
values and station observations. The project results in two 1M5 maps: one based on daily values
from midnight to midnight in line with the earlier 1M5 map, and the other

of more than a hundred valley glaciers (Bahr and others, 1997). The regression lines are of the

where v and s are glacier volume and area, respectively. The coefficient and exponent for the
Icelandic ice caps are c = 0:048, g = 1:23, when the area and volume are expressed
