River Wylye Geomorphological Assessment (Completed Date: Dec 2006)

Restoration work has been undertaken on the River Wylye in Wiltshire (a chalk stream designated as a SSI and SAC) in order to address low flow issues relating to abstraction for public water supply. David was involved in undertaking a geomorphological survey of a number of restoration sites along the river, repeating a previous survey undertaken in 2001. Analysis of the data sets using GIS allowed for the assessment of the success of the schemes with reference to their ability to improve geomorphological diversity.

Queensmead Restoration (Completed Date: Apr 2009)

Arup were appointed to undertake a study to assess a range of options for flood storage and river restoration on the heavily-channelised Ravensbourne River, as part of a wider River Corridor Improvement Plan. David was part of the team involved in the completion of a Flood Risk Management pre-feasibility study including an assessment of the existing flooding mechanisms of the watercourse, identification of the options available to restore the existing channel, and a hydraulic assessment of the options identified.

David is an experienced specialist field geomorphologist and flood risk manager, with a strong interest in advanced measurement techniques including LiDAR. Davids daily project work relates to River Restoration, Geomorphological Appraisal, Flood Risk Management, Hydraulic modelling, Flood Forecasting, and Sediment Transport. David has expertise relating to meander theory, pool-riffle maintenance, open-channel hydraulics and sediment transport. David has a PhD on the use of remote sensing the river environments.
