Standard histories of geomorphology tend to identify a basic conflict between 2 extremes: 1) timebound, desriptive regional studies of landscape evolution; and 2) timeless analysis of process mechanics. The A. argues that we need to ask a new type
-scale site-specific research. 3 related themes are considered: the nature of the link between channel form and process revealed by intensive study of a dynamic river system; the significance of the conditional role of channel geomorphology in this link
A dated landscape history of the Allt nan Uamh valley in the Assynt area is constructed, spanning the last 300 ka, using geomorphological analysis, U-series speleothem dating, and existing cave surveys. The mean rate of valley deepening is estimated
of landscapes as they evolve. The diffusion equation was introduced into geomorphological reasoning for this purpose. Diffusivities estimated in this study are compared with values derived in scarp studies and values adopted in landscape development models
The major link between geomorphology and basin analysis is the sediment flux from catchment to basin. It is the various controls (lithological, morphological, climatic and botanical) upon the magnitude of sediment flux that link the 2 subjects
