The project is designed as a joint field measurement and numerical modelling program. Surface drifters will be used to measure the flow velocity at different depths within the surface boundary layer.

Each drifter will be equipped with a GPS tracker to record the position, and an accelerometer to measure the local wave conditions. Drifters will be used to measure both the absolute rate of transport and relative dispersion between drifters deployed at the same depth.

Numerical models simulations will be conducted using a model modified using a wave mixing parameterization scheme suggested from recent literature, with the aim to investigate the suitability of such a scheme in conditions with a shallow surface boundary layer.

The outcome of the project is expected to improve our knowledge about dynamics of shallow surface boundary layers and the numerical modelling representation of these processes.
