Spatial analysis of solifluction landforms and process rates in the Abisko Mountains, northern Sweden
Abstract The occurrence of turf‐banked solifluction landforms in the Abisko region was analysed using a grid‐based approach and statistical modelling through logistic regression. Significant parameters in the model were the vegetation index NDVI, annual incoming potential radiation, wetness index, s...
