Coast and river research
Our coast and river research investigates the natural processes operating on the landscape, from catchment to coast.
We conduct studies across a range of temporal and spatial scales, from catchment to cobble, from Holocene to a few days. Our analyses of landscapes utilise many methods, including numerical modelling, and considerable fieldwork, in which we use seismic imagery, ground-penetrating radar, subsurface coring, terrestrial laser scanning, structure from motion, and a suite of wave and current sensors.
We examine a range of dynamic landscapes including river catchments and a variety of open-coast settings, such as river deltas, sand and gravel beaches, shell cheniers, rocky shorelines, and tropical coral reef environments.
Much of our research is concerned with sediment transport and morphodynamics, but we also address the interactions of physical and ecological processes. Our findings aim to frame environmental management applications, including assessments of shoreline erosion and river rehabilitation options.
