EUROWAVES incorporates an easy to use gridding routine. An initial computational area is
selected by the user and a default grid is set up automatically (a nested grid is used by SWAN).
However, the user may easily make changes to the grid. The user next selects the target point
of interest. Default formulations of the bottom friction may be overriden by the user if better
local information is available. It is also possible to impose an increase in the water depth,
associated, for example, with a storm surge. Having chosen the grid, the target point and the
offshore boundary points (Figure 3), one can choose either to run a time series (as provided in
the EUROWAVES data base or input by the user) or to make a single run, in which case the
user is asked to specify the wind and wave conditions at the selected boundary points. In the
latter case, having performed the run, the output can be inspected as a contour plot over the
whole area (Figure 4; also for Venice, which is run for all grid points to construct a wave field)
or as a directional wave spectrum at the target location (Figure 5). In the case of a time series
run, the long term wave data at the target point can be analysed by the nearshore statistics
module (the presentations are similar to the offshore ones, Figure 2)
