Moored upward-looking acoustic Doppler current profiler

The use of a moored (sitting on the bottom) upward-looking acoustic Doppler current profiler (ADCP) allows to capture hydrodynamics of water column above the instrument. It is also possible to couple those profiles with variations in water depth.

Microseismic Sea Cliff Motion

Broadband seismometers can be deployed at three (or more) separate terrace-top seismic stations along a transect perpendicular to the sea cliff edge.These instruments measure velocity for three separate directions of ground motion (e.g. vertical, north-south, and east-west). These ground motion velocities can be differentiated to obtain ground accelerations, or integrated to obtain absolute displacements.

Experimental Analysis of Erosive Cohesive Coastline Morphology

Laboratory experiments have been performed in a wave flume to investigate the coastal cliff recession under regular waves forcing. The different processes of the cliff erosion cycle are described and we focus on bottom evolution, which seem mostly depend on the surf similarity parameter ξ. We observed steep planar (ξ > 0.7), gentle planar (0.5
