Anders Rapp (1927–1998) was a Swedish geomorphologist and geographer who pioneered quantitative geomorphological approach on mass movements and erosion. He was the first to make a comprehensive study on avalanche boulder tongues. Most of Rapp's works were made in the Scandinavian Mountains and Spitsbergen including the areas of Kärkevagge near Abisko and Kebnekaise.[1]
Studying under Filip Hjulström, Rapp got his Ph.D. at Uppsala University in 1961,[2] and was appointed professor of physical geography at Lund University in 1977.[3] In 1980, he was elected a member of the Royal Swedish Academy of Sciences.
Research contributions
[edit]Building on the process-geomorphology tradition of his supervisor Hjulström, Rapp introduced systematic sediment-budget techniques to cold-region landscapes. His 1961 thesis on the Kärkevagge valley quantified every pathway by which rock is liberated from frost-shattered cliffs, transported downslope by avalanches and debris flows, and ultimately stored in valley-floor talus—demonstrating that avalanche boulder tongues can move blocks more than 70 tonnes at mean rates of 0.5 metres per year. The work became a benchmark for coupling climate, slope process and landform evolution, and earned him the Kirk Bryan Award of the Geological Society of America in 1962.[4]
From 1966 to 1976 he led Sweden's contribution to the [International Hydrological Programme|International Hydrological Decade]] high-mountain programme. Instrument arrays on Kebnekaise recorded that suspended-sediment yields during summer snowmelt were an order of magnitude higher after snow-avalanche winters than after wind-blown winters, demonstrating the role of winter climate in controlling annual denudation budgets. Parallel expeditions to central Spitsbergen mapped sorted-circle fields and dated debris-flow lobes, providing the first process rates for high-Arctic periglacial slopes.[5]
