are expecting further changes in the future and these future changes are considered along with many other uncertainties in the design and operational plans for new installations. Substantial changes in the operational environment of the energy industry are also expected due to indirect effects of climate change, such as international agreements to curtail CO2 emissions and a changed role of hydro-power

1 Introduction
Flood frequency analysis is a prerequisite in flood risk assessment studies and for the design
of various hydraulic structures. Often, flood quantile

Since
Thursday the tremor had been intermittent. Today, Monday 30 May, it
has been confirmed by the participants of Iceland Glaciological
Society's spring expedition that the eruption has ended.
The end of the Grímsvötn eruption is set to 7 UTC Saturday morning
28 May 2011.

tlement, glaciers were smaller than at present. They started
to advance in the 13th century at the onset of the Little Ice
Age that lasted until late 19th century when most glaciers in
Iceland reached their maximum extent. In the 20th century,
the climate was significantly warmer than during the Little
Ice Age, with higher temperatures in the period 1930–1945

These calculations can then
be used as the basis for flood warnings and in the design of the built environment. A newly
published Icelandic study by Massad et al. (2020) reassessed precipitation return levels in
Iceland, resulting in a new national map of 24-hour precipitation thresholds for a 5-year event,
see Figure 1, in agreement with the general precipitation pattern in Iceland, shown in Figure 2
