Improving soil erosion assessment in Swiss Mountainous areas using radionuclides (137Cs, 239-240Pu)

Description: Das Projekt "Improving soil erosion assessment in Swiss Mountainous areas using radionuclides (137Cs, 239-240Pu)" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Universität Basel, Umweltgeowissenschaften.To efficiently mitigate and control soil losses by erosion and reduce their environmental impacts in Alpine grasslands, reliable and validated methods for comprehensive data generation on the magnitude and spatial extent of soil erosion are needed. Classical approaches to quantify erosion rates include artificial radionuclides such as 137Cs and 239-240Pu which originated from thermonuclear weapon tests in the 1950s-1960s and nuclear power plant accidents (i.e. Chernobyl). Because these radionuclides are rapidly and strongly adsorbed to fine soil particles, they accumulate in the top soil with limited migration and bioavailability. Documenting the subsequent redistribution of the radionuclides, which move across the landscape in association with soil/sediment particles primarily through physical processes, requires effective means of tracing rates and patterns of erosion and deposition within landscapes. To this end, the general aim of this project is to develop a radio-isotopic valid approach to assess and quantify sheet erosion in Alpine grasslands.
