CMIP5 climate projections and RUSLE-based soil erosion assessment in the central part of Iran

Abstract Soil erosion (SE) and climate change are closely related to environmental challenges that influence human wellbeing. However, the potential impacts of both processes in semi-arid areas are difficult to be predicted because of atmospheric variations and non-sustainable land use management. T...
