Dr Tim Meadows (Geography, SEED, University of Manchester)
Modelling decadal-scale morphological evolution of the upper North Fork Toutle River, Mount St Helens, USA
Management of sediment-related hazards following large explosive eruptions is currently hampered by limited understanding of the nature and duration of long-term fluvial geomorphic response in affected catchments. Reduced complexity, landscape evolution models offer a potential means of developing quantitative, process-based predictions which can be used to inform sustainable management efforts. However, these models have been criticised for the simplified ways in which they represent processes and their applicability in practice has yet to be fully demonstrated. This seminar describes an evaluation of the CAESAR-Lisflood landscape evolution model in the volcanically-disturbed upper North Fork Toutle River catchment, and presents predictions of morphological evolution and resultant sediment yield to the end of this century.
Tim is a fluvial geomorphologist with particular interest in how rivers respond to natural and human-induced disturbances. His current research is focused on using numerical models to better understand processes of river change in severely disturbed catchments over timescales relevant to planning and management. Prior to joining the University of Manchester in 2016, Tim obtained a PhD from the University of Nottingham before working as a geomorphologist for the Scottish Environment Protection Agency and the Environment Agency.
