Climate Change and Debris-Flow Events in Southern Norway
Matthews, J.A., Dahl, S.O., Dresser, P.Q., Berrisford, M.S.,
Lie, O., Nesje, A. and Owen, G. 2009. Radiocarbon chronology of
Holocene colluvial (debris-flow) events at Sletthamn,
Jotunheimen, southern Norway: a window on the changing frequency
of extreme climatic events and their landscape impact. The
Holocene 19: 1107-1129. In an effort to explore this question
using real-world data, the seven scientists conducted detailed
investigations at three alpine slope-foot mires located in the
valley of Leirdalen in an area known as Sletthamn, above the
treeline among some of the highest mountains in southern Norway,
where they say that "exceptionally detailed radiocarbon-dating
controlled chronologies of Holocene debris-flow events have been
reconstructed," which allowed them to analyze "the frequency and
timing of debris flows since c. 8500 cal. BP which, in turn, are
related to climatic variability, extreme climatic events and
site conditions." Results indic
