We combine analytical modelling and laboratory experiments to understand how patchy vegetation dissipates and redistributes wave energy. Our results show that diffraction can extend wave attenuation into unvegetated gaps, with the pattern governed by wavelength relative to vegetation spacing.

We combine laboratory experiments and modelling to predict wave attenuation when currents cross the wave direction. Our published work addresses orthogonal conditions (90°), and our broader research also examines oblique conditions at other crossing angles.

We combine laboratory experiments and modelling to study how submerged vegetation patches alter flow, turbulence, and sediment erosion. Our results link vegetation density and coverage to local scour and show how bedforms and turbulence develop together.

We study hybrid shore protection that combines engineered structures with living vegetation. Laboratory tests with live mangrove seedlings show that concrete planters provide most of the wave attenuation at this early growth stage, with arrangement and submergence affecting performance.

We are developing imaging methods to monitor submerged vegetation and structures. The project investigates whether their motion can reveal local flow conditions, with the aim of complementing conventional sensors. This work will continue under the new CFI V2-P9 project.
