Abstract
A field experiment has been carried out to examine the nature of sediment suspension and transport in front of a seawall. Synchronous high frequency measurements of surface elevation (using pressure transducers), water velocity (using electromagnetic current meters) and suspended sediment concentrations (using optical backscatter sensors) have been taken from in front of the Brunel seawall at Teignmouth, South Devon, UK. Measurements were also made simultaneously on an adjacent natural beach to provide control data. Wave reflections from the seawall lead to an increase in suspended sediment concentrations, and alter the phase of sediment suspension. The results emphasize the importance of wave reflection on the dynamics of beaches backed by seawalls.
