Abstract

The paper provides a methodology for the teaching and learning of catchment landform and processes and their linkages to the dynamic behaviour of river channel form and process. Fieldwork is described. An overview is provided of the processes and landforms of the study area. The paper is focused on teaching and learning. In addition it emphasises the need and importance of research into two key areas: (1) the spatial and temporal variation in sediment sources and their direct linkage to channel change using tracer studies; (2) the quantification of sediment-borne heavy metal contamination in the river channel and the efficacy of current engineering works in reducing contaminated sediment transfer to the channel and enhancing channel stability.
