Researchers in the COAST Lab
The Coastal, Ocean and Sediment Transport (COAST) laboratory provides physical model testing with combined waves, currents and wind, offered at scales appropriate for device testing, array testing, environmental modelling and coastal engineering. 
The facility is closely aligned with the COAST Engineering Research Group.
Explore some of the projects that have benefitted from the state-of-the-art facilities in the lab.

STORMLAMP – Structural behaviour Of Rock Mounted Lighthouses At the Mercy of imPulsive waves

Researchers used a combined program of field measurements, laboratory studies and analytical and numerical investigations to enable characterisation of environmental loading and performance to support management of lighthouse structural condition. The team were able to gather valuable data from progressive testing in both the 35m sediment flume and the Coastal Basin.

FROTH - Fundamentals and Reliability of Offshore Structure Hydrodynamics

FROTH – Fundamentals and Reliability of Offshore Structure Hydrodynamics 

The aim of this research was to investigate the detailed physics of violent hydrodynamic impact loading on rigid and elastic structures through a carefully integrated programme of numerical modelling and physical experiments at large scale. 
Models of 1:100 scale were fixed to the gantry in the University of Plymouth Ocean Basin for the first scenario. Further tests were carried out in heave motion only, heave and pitch and in full 6 degrees of freedom (6 DOF) floating scenarios.

Particle Image Velocimetry (PIV)

Particle image velocimetry (PIV) is an optical method of flow visualization used in education and research. It is used to obtain instantaneous velocity measurements and related properties in fluids.  Dr Edward Ransley has used PIV in the COAST Lab to great effect as these images and video’s demonstrate.

COAST Engineering Research Group

The COAST Engineering Research Group is a leading team of coastal and ocean engineering researchers carrying out both fundamental and applied research.
The group contains recognised specialists in laboratory modelling, numerical modelling, field experimentation and theoretical analysis. We focus on major problems facing society regarding rising sea levels, flood risk, and marine renewable energy which have been highlighted in recent government reviews.
