Sediment transport processes in the presence of intense currents

Context

Tidal turbines will be deployed in extremely energetic environments that may induce an intense sediment transport. This process threatens the proper functioning of the turbines and may shorten their useful life-span. The lack of knowledge on the sediment transport processes occurring at tidal energy sites must be reduced to allow optimal turbine design and to reduce the tidal energy industry LCOE.

Objective

To improve hydro-sedimentary modelling through measurement campaigns

Main achievements

Definition of the data acquisition strategy including the choice of measuring instruments and the design of their supports

In-situ measurement campaign in the Alderney Race and recovery of the deployed instrumentation

Development of a regional hydrosedimentary model of the Alderney Race covering the real conditions of the area and based on in-situ observations as well as micro-scale simulations

Main outputs

4 measuring cages and various instruments that can be attached to them: ADCP 5-beam, hydrophone, acoustic receivers, stereo video, camera
Databases: currentology and hydrosedimentary processes measured with 2 ADCP current profilers, 2 point current meters, 4 hydrophones and acoustic pebble tracing – Alderney Race (North-West of the temporary occupation permit zone) – September 2017 to May 2018
