Beach erosion / deposition


WES have two main ways of monitoring the rate of erosion or deposition of bed material within the inter-tidal environment.



The instrument pictured below is a high resolution autonomous acoustic device which can accurately record subtle changes in bed elevation in estuarine muds for example. It can be left unattended for long periods recording data to a solid state logger in a submersible housing.

The devices pictured below are in-house developed instruments utilising the unique "*Tell-Tail" system designed to autonomously monitor relatively large changes in beach levels.
