Users with a specific interest at a coastal location have applied the automatic downscaling procedure. These cases are typical when the final aim is to design a coastal/harbour structure, or a coastal protection system. It is therefore required that the meteoceanographic parameters statistics (average and extremes) are calculated at the exact point where the structure/system is foreseen, taking into account all the physical processed that affect the waves transformation in their propagation from offshore to inshore.
These application normally are based on three steps:

• analysis of the data available at grid point, to describe the offshore wave and winds climate.
• application of the downscaling procedure, to produce a new wave time series at the point of interest.
• analysis of the new time series, to describe the inshore wave climate and extrems.

These users have finally obtained three detailed documents, that can be used for example as three main chapters in a design report, or can be three large appendixes.

Some users have asked SEEWAVE to provide a complete, ready to be used, meteoceanographic report for selected coastal areas. SEEWAVE has therefore taken care of the application of the procedure, and has carried out further detailed analyses that are not automatically covered by the dashboard. Example step-by-step procedure is as follows:

• Detailed description of the area of interest, with large and small scale figures, also describing the bathymetry
• Wind climate description, in terms of average (wind roses, frequency tables, etc.) and extremes.
• General exposition of the site to sea waves (geographical and effective fetch calculation and figures)
• Calibration of the available offshore wave time series; this procedure is based on satellite data and, if available, on direct (i.e. buoy) measurement. The output are the calibration factors that are to be applied to the offshore wave parameters.
• Offshore calibrated wave climate description, in terms of average and extremes.
• Downscaling of the wave time series, by application of the inverse ray tracing model and, if required, of the advanced state-of-the-art SWAN (Simulating WAves in the Nearshore) model, also able to account for the wave breaking in shallow waters.
• Detailed analysis of the average and extreme statistics of the inshore downscaled wave time series, in order to provide the actual required parameters for the engineering activities.
• Sea levels analysis, calculating the astronomical tide parameters and the meteorological surge using dedicated statistical analyses. This step can be carried out on the basis of direct measurements when available in the area or using global coverage databases of hindcasted water levels.
