Quantifying sediment fluxes from acoustic Doppler current profilers Mar 1, 2018 - Apr 30, 2021
Calibration of the Environment Agency's ADCP units and back calculation of historical suspended sediment loads for selected sites.
Project Description
Flooding is a first-order risk facing people and infrastructure globally. It is both costly – the floods of the 2015/16 winter cost the UK £1.6bn - and a major threat to life. Such is its importance, understanding the drivers and impacts of flooding at local and regional scales is central to the UN’s Sustainable Development Goals, and integral to national funding calls such as the Global Challenges Research Fund (GCRF). Flooding and geomorphology are linked - landslides and debris flows can exacerbate the flood risk (Borga et al., 2014), and changes to channel profile feed back into the spatial and temporal extents of inundation (Lane et al, 2007; Slater, 2016). As Geomorphic activity is also linked to hydrological activity in a non-linear fashion (Coulthard et al, 2012), it is likely increases in storminess may exacerbate the risk posed by geomorphic hazards (due to sediment erosion and transportation) to a greater extent than the risk faced by flooding. Yet, despite this, geomorphology is often not considered in flood risk forecasting frameworks (Flack et al, in prep).
