behavior as the models we would like to compare it with – Campbell,
Joyner and Boore, and Fukushima and Tanaka–despite the generally lower predictions.
Campbell's model is only valid for distances less than 50 km since his data set, of magnitude 5
to 7.7 events, consisted only of observations close to the epicenter (more than 86% were closer
than 30 km).

altimeters at different orbits perform slightly less accurate measurements up to 82 N and S (Rhein
et al., 2013). These records are used to estimate sea surface changes and calculate global mean sea
level, a temporal average sea level averaged over the oceans (Church, Clark, et al., 2013

land. It is the second largest aviation service region in the world. Over the course of a decade IMO was modernized
and sta?ed to meet the highest international requirements. The Icelandic public and economic sectors, in particular
the fisheries, transportation and agriculture, benefitted hugely from this development making

principles would often not
match up exactly, as happenend with the steps, we
reconstructed seven “umbrella principles.” Under
each of these, we listed a number of similar
principles in a principles summary table (Appendix
4: Table A4). We discussed the meaning of each
umbrella principle and the comparison of its
underlying principles from the four guides in the
right-hand column, as well as agreement

Water Framework Directive (Directive 2000/60/EC),
Common Agricultural Policy, etcetera], except for the
Ukrainian part of the Tisza. However, the Ukraine shows
strong incentives to enter the EU community and thus the
EU acquis communautaire is used as key reference for the
development of its water management principles. It was
nevertheless decided to select two case-studies
