Project Description

Characterisation of River Bed Surface Structure - Funded by NERC. (2012 – ongoing) Changes to the sediment bed surface in gravel rivers to accommodate both the overlying fluid flow regime and the upstream sediment supply fundamentally changes the overall stability of the river. To date, being able to describe changes to river stability in response to changing ‘bed structure’ and explicitly linking this development with changes to the overlying hydraulic signatures and sediment transport characteristics has been severely limited. This project aims to address this deficiency specifically examining how sediment grade, sediment supply characteristics and hydrograph shape affect the development of surface structures in gravel-bed rivers.
