REAL TIME SAFETY ON SEDIMENTARY COASTS
Coastal defence works in large parts of Netherlands and on the southern coast of Great Britain consist of sedimentary berms and dunes. The coastal authorities therefore need up-to-date information about the actual condition of the coastline and the associated trends. This information is used as a basis for decisions to manage coastline regression and it includes data about overtopping, dune erosion and flooding during storms. This allows coastal authorities to monitor whether coastal defences provide protection against flooding. Monitoring the coastal zone also contributes to the safety of bathers.
A general architecture for the operational model system (the "OMS") was developed last year and so the system now supports the monitoring and forecasting of waves, water levels, and beach and dune erosion. The system draws on remote sensing, image processing, and hydrodynamic and morphological models.
