David Milan : Geomorphic response and recovery of upland river catchments to extreme floods

On The June 21, 2021

Implications for sediment and flood risk management in a wetter world: Extreme rainfall events can result in dynamic responses to upland river systems; activating the sediment system at the catchment-scale, increasing sediment transport, and initiating channel morphological change.

This seminar focuses on the dramatic response of Thinhope Burn, a headwater tributary to the River South Tyne, UK, to a flood in the summer of 2007. Modelling and field studies, conducted over the last 13 yrs, suggest that once upland river systems are activated, many may not recover in a wetter climatic regime, hence having implications for future gravel management for flood defence in upland rivers in the UK.
