Implications of climate variability and changing seasonal hydrology for subarctic riverbank erosion
Abstract Warmer climatic conditions have been associated with numerous hydrologic changes that may impact riverbank erosion in cold regions, but the net effect is not well understood. We used regression and correlation analyses to examine the relationships among subarctic riverbank erosion and seaso...
