Predicting wind waves within confined and shallow basins is very important, given the
decisive role they play in the resuspension mechanisms of sediments and nutrients
from the bottom, on which the main morphological and environmental changes
depend. Pascolo et al. (2019) proposed a set of wave forecasting curves for fully
developed conditions in finite depth, which consider the bottom roughness as an
additional variable, since it plays a fundamental role in the wave energy dissipation
during the generation process. The present study incorporates and integrates the
results previously obtained by Pascolo et al. (2019) and provides the growth curves in
the complete form, taking into account also the limitation on fetch. A numerical
approach on a simplified domain has been adopted and statistical analyses on the fit of
the curves to numerical results have been performed. The new set of equations
confirms the variability of the wave heights and periods as a function of the bottom
conditions which can change due to the presence of bedforms, vegetation or particle
size differences. Applications at different conditions of depth, fetch and roughness
have been analysed, in order to confirm the validity of the new growth curves.
