Storm monitoring and warning systems

Timestack type images are used to monitor the rise and fall of waves and overtopping along different transects defined along coastal areas in general (beaches, ports, road infrastructures, etc.). A tool has been developed for the automatic detection of overtopping by analysing the evolution of the intensity signal over time. This information is used by the Basque Government’s Emergency Directorate to monitor the impact of storms on the coast.
