A prediction and warning system against sea-related hazards is being developed on behalf of the Local Authority of the Salerno Province (Southern Italy) by CUGRI, a research centre which specializes on hazard prevention. The system, which is in turn part of a more general civil protection plan, will be organised around four subsystems: a) Weather alert; b) Offshore sea state forecast; c) Wave transformation towards the coast; d) Run-up modelling.

While subsystems a) and b) will be largely based on Italian and/or European Meteorological services supplied under contract, and partly shared with other sectors of the Civil Protection and other coastal regions, subsystem c) and d) are very specific to the area considered. Wave shoaling and run-up will be evaluated with both experimental formulas and specialized software. The paper presents a general outline of the whole sea hazard plan and shows results of sample calculations of run-up and potential damage assessment in several coastal sites, carried out by making use of sea state data derived from recorded and synthesised data of previous storms and from extreme value analyses of the sea climate in the area.
