Providing models to assess management options
A comprehensive assessment of the coastal processes and observed erosion in the West Beach sediment cell has been undertaken using a combination of analysis of existing data sets and a state-of-the-art numerical modelling framework for the modelling of long-term shoreline evolution.
Driven by MIKE Powered by DHI software, hydrodynamic (MIKE 21 Hydrodynamics Flow Model), wave (MIKE 21 Spectral Waves) and shoreline morphology (MIKE 21 Shoreline Morphology) models were developed and calibrated based on available measurements.
In total, six management scenarios comprising of combinations of soft management options (nourishment, backpass systems) and hard structures have been simulated. For each scenario, the morphological evolution of the entire West Beach shoreline has been simulated for 7.5 years providing comparative assessments of the pros and cons of each scenario.
