In this project, the calculation of return levels was done using the R programming language (R
Core Team, 2014) with a package called extRemes (Gilleland and Katz, 2016). The package
provides many functions and visual tools for EVA. The main functions used in this project
covered the fitting of GEV and GP distributions using MLE or L-moments methods, in addition
to a declustering function

and are thought to do so in the future as well. Therefore, a coastal flooding
risk assessment needs to be made for Iceland. A risk assessment is currently in the early steps of
preparation and a fitting method needs to be developed. To facilitate the process, an overview of
the methods used in neighbouring countries is provided here and the suitability of the methods for
Iceland is discussed.

variations have been removed by the statistical analysis.

4. Scenarios of monthly mean temperature and accumulated precipitation where
calculated from 2010 to the end of the climate simulation by fitting a least
squares line to the monthly values simulated by the RCM or GCM from 2010
onwards and shifting the simulated time

than can be expected to originate from the cauldrons, three to four times the wa-
ter equivalent of the accumulation of snow over the watershed of the cauldrons. It has
been estimated that flow from the cauldrons, in addition to the jökulhlaups, could be
2–5 m3 s 1 at maximum (Vatnaskil, 2005). It is possible that part of the sulfate-rich
groundwater from the glacier comes from the cauldrons
