vatnsárunum
1979 til 1989 var meðalrennsli júnímánaðar 91 m3/s en á vatns-
árunum 2008 til 2018 var það 71 m3/s. Þarna koma minni vorleys-
ingar glöggt fram. Ef ársmeðalrennslið er skoðað er það 38 m3/s
yfir fyrri áratuginn en 42 m3/s yfir seinni áratuginn. Þar fer munurinn
í öfuga átt og rennslið hefur vaxið.
Aukin úrkoma mælist nú á Norðurlandi og jöklar hafa rýrnað og
skilað vatni. Tíminn sem

mass balance of three small ice caps (with areas from 15 to 80 km2) over 6 to
20 years, were efficiently estimated from maps of glacier elevation changes deduced by SPOT
5 HRS, EMISAR and aerial photographs
• Accuracy of estimating the elevation changes, was greatly improved by using the highly precise
EMISAR DEM as a reference for co-registration and offset correction
