Abstract

Spatial and temporal variation in river bank erosion rates in a British upland catchment was quantified over a 2 year period using a network of erosion pins. Potential causal mechanisms and site-specific controls of this erosion were examined through bivariate analyses and significance testing. Problems with existing process-inference methodologies were identified and addressed through the application of a novel technique involving the disaggregation of erosion pin data using a combination of morphodynamic behaviour descriptors and hierarchical cluster analysis. Fluvial processes were identified as the dominant driver of morphological activity in the study area, contesting the notion that subaerial processes are more significant in the headwater reaches of river catchments. The results indicate that the existence and spatial organisation of “process-intensity domains” may be influenced by extreme geomorphological events and/or wider catchment-scale changes that have affected hydrology and sediment supply processes
