Any tectonic forcing acting on a mountain range consists of vertical uplift motion and horizontal advection motion. In landscapes with a high advective component, such as those affected by low angle normal faults, advection can form a substantial por

Pebbles become rounded during fluvial transport. Roundness, along with other shape factors, size and lithology, are commonly used in sedimentology to link the fluvial transport distance and consequent abrasion prior to deposition. Although roundness

Due to the limited resolution of freely available digital elevation models (DEM), DEM-derived river products cannot provide accurate flow lines in inland and lowland areas. Stream burning is used to improve the accuracy of extracted flowlines in addi

Inferring erosion rates from 10Be or 26Al concentrations in stream sediments has become standard practice in geomorphology. In formerly glaciated landscapes, however, this technique is problematic because repeated phases of shielding and exposure dur

Flood hazard maps used to inform and build resilience in remote communities in the Terai region of southern Nepal are based on outdated and static digital elevation models (DEMs), which do not reflect dynamic river configuration or hydrology. Episodi

This study uses the 2015 ‘Storm Frank’ flood on the River Dee, Aberdeenshire, to assess the impact of extreme events on river dynamics. The Storm Frank flood (>200 year recurrence interval) caused significant local morphological change that was c

Climate change and land-use change impact the sediment flux and grainsize delivered to rivers which influences channel morphologies and hence modifies flood risk; this is particularly the case where channels are fed by high mountain catchments. Here,

Large earthquakes can contribute to mountain growth by building topography, but also contribute to mass removal from mountain ranges through widespread mass wasting. On a shorter timescale, large earthquakes also have the potential to significantly a
