Although mangrove forests have proven to contribute to wave dissipation significantly, these ecosystem are threatened mainly by the expanding aquaculture. International or nationwide applied greenbelt policies are often used for the preservation of the mangroves and hence the flood hazard reduction, without taking local (hydrodynamic) conditions...

Fire Island has been monitored since Hurricane Sandy (2012). During that period, Fire Island showed recovery (accretion on the island). Behaviour of the recovery is not yet well-known. Main processes during the recovery are also not known. Therefore, the emphasis of this thesis is on the understanding of the main processes of the recovery of...

De aanleiding voor dit afstudeerwerk was de constatering van Holland Railconsult dat hun begrotingen vaak lager waren dan het laagste bod bij een aanbesteding en dat zij vermoedden dat er een grotere marge rondom de begroting benodigd is om met een bepaalde betrouwbaarheid het laagste bod te vangen dan men in eerste instantie dacht. Men wilde...

This thesis studies the relation between short wave groups and long wave motion in the shore-normal case on a uniformly sloping bottom. The short wave groups can be described through two time scales; the time scale of the individual waves and the time scale of the groups. The energy of the individual waves is dissipated through wave breaking and...

Since 1992 nearshore hydrodynamics and coastal morphology have been studied from ARGUS video images, collected every hour at eight beach locations worldwide. Identification of the waterline from these images would enable us to obtain an impression of the intertidal beach bathymetry, and hence to monitor intertidal beach morphodynamics. In this...

Cross-shore sediment transport is an important phenomenon in coastal engineering, which mainly accounts for the short-term changes in the coastline. To study on- and offshore transport the evolution of the beach profile is considered. For investigation of the beach profile small-scale physical models are often used. A problem in using a physical...

A description is given of a model developed for the prediction of the dissipation of energy in random waves breaking on a beach. The dissipation rate per breaking wave is estimated from that in a bore of corresponding height, while the probability of occurrence of breaking waves is estimated on the basis of a wave height distribution with an...
