| Zusammenfassung |
| A methodology to assess storm-induced coastal vulnerability taking into
account the different induced processes separately (inundation and erosion)
is presented. It is based on a probabilistic approach where hazards time
series are built from existing storm data and later used to fit an
extreme probability function. This is done for different sectors along the
coast defined in terms of the wave climate and for representative beach
types of the area to be analyzed. Once probability distributions are
available, coastal managers must decide the probability of occurrence to be
accepted as well as the period of concern of the analysis in function of the
importance of the hinterland. These two variables will determine the return
period to be considered in the assessment. The comparison of hazards and
vulnerabilities associated with the selected probability of occurrence
permit to identify the most hazardous areas along the coast in a robust
manner by including the spatial variability in forcing (storm climate) and
receptor (beaches). The methodology has been applied to a 50 km long coastal
stretch of the Catalonia (NW Mediterranean) where offshore wave conditions
can be assumed to be homogeneous. In spite of this spatially constant wave
field, obtained results indicate a large variability in hazards intensity
and vulnerability along the coast. |
