a systematic com-
parison of results to observed precipitation has been carried out. Un-
dercatchment of solid precipitation is dealt with by looking only at
days when precipitation is presumably liquid or by considering the
occurrence and non-occurrence of precipitation. Away from non-
resolved orography, the long term means (months, years) of observed
and simulated precipitation are often

Impact of climate and land use change on the hydrology
of a large-scale agricultural catchment

Received 5 December 2007; revised 21 November 2008; accepted 19 January 2009; published 18 March 2009.
[1] This paper presents a quantitative comparison of plausible climate and land use
change impacts on the hydrology of a large-scale

Conclusions of the Scientific Advisory Board of the Icelandic Civil Protection:
The eruptive activity at Holuhraun continues at similar intensity.
o The eruption sites are the same as before. Lava flows to the East at similar
rates as yesterday. Although the lava is now in contact with the river Jökulsá
á Fjöllum, it does not reduce the lava flow rates significantly. No explosive
activity
