Details

This project developed a collection of numerical models to simulate the movement of water near the shore. These ANEMONE (Advanced Nonlinear Engineering MOdels for the Nearshore Environment) models improved predictions of surf zone hydrodynamics and the way sediment is transported.

These numerical models cover non-linear surf zone processes, including:

• wave breaking
• the transfer of energy between primary wave components
• low-frequency waves

This project improved understanding of coastal systems and processes and the influence of sea defences on these processes. This will improve the efficiency of coastal defence design and management to achieve better value for money and reduce the disruption to natural processes.

This project ran from 1994 to 1999 at a cost of £365,000.
