Zusammenfassung |
This paper deals with the limits in hydrodynamic and morphodynamic
predictions for semi-enclosed coastal domains subject to sharp gradients (in
bathymetry, topography, sediment transport and coastal damages). It starts
with an overview of wave prediction limits (based on satellite images and
buoy records) in a restricted domain, namely the Mediterranean basin,
followed by an in-depth analysis of the Catalan coast, one of its land
boundaries. The morphodynamic modelling for such regions is next discussed,
based on the impact of a characteristic storm. The driving wave and surge
conditions produce a morphodynamic response that is validated against the pre-
and post-storm emerged beach state, recovered from two lidar images. The
quality of the fit is discussed in terms of the physical processes and the
suitability of the employed modelling suite. From here an assessment of
errors and uncertainties is presented, with the aim of establishing the
prediction limits for flooding and erosion analyses, key elements for coastal
engineering decisions. |
