Application of geomorphology to prediction of landform response to disturbance, in particular in the context of natural hazard and disaster management. Mechanics of river and debris flow behaviour, and management of the resulting hazards. Analysis and modelling of the initiation and runout dynamics of large coseismic landslides. Formation and failure of landslide dams, dambreak floods and landslide-dam induced aggradation. Physical modelling of geomorphic processes.
