Principal aim: To resolve mechanisms, patterns and rates of erosion, their controls, and their role in landscape evolution to enable interpretation of the landscape as a record of past environmental change, to predict effects of future environmental and climate change, and to evaluate and mitigate natural hazard risk.
In this theme we are concerned with the mechanics of erosion on hillslopes, in river channels, and in glacial, aeolian and marine environments, and the mathematical representation of these processes. In addition, established and novel techniques are used to quantify shallow exhumation and denudation over a range of time scales, in support of observational studies of landscape dynamics. These techniques will include OSL thermo-chronometry and Raman spectroscopy in addition to thermochronometric and geochemical approaches. Observational insights are combined with theoretical considerations and numerical and physical modelling to advance understanding of the erosional evolution of topography. This theme, within the heartland of Geomorphology, provides an anchor and forum for other, inter-disciplinary activities of the group.
