Beneath the pavement, the beach: A semantic exploration of time, space, and their volume of permutations through Lebanon's littoral

This thesis is about the convergence of two boundlessly enigmatic dimensions; turbulent coastal morphodynamics of a vanishing coastline in the presence of acute geo-political conflict. The Lebanese coastline undergoes a permutation of intertwined anthropogenic and natural forces, ensuing its exponential recession, deterioration, and...

Beach development in Oranjestad Bay, St. Eustatius: A study of the morphological system and possible coastal solutions for the creation of a beach

Sint Eustatius is a Caribbean island located in the north of the Lesser Antilles. The coastline west of the capital, Oranjestad Bay, is of vital importance to the island as it is here where tourism, recreation, the harbour and historical ruins are located. On the other hand, Oranjestad Bay has a heavily fluctuating beach, which is undesirable....

Large-scale morphological changes and sediment budget of the Western Scheldt estuary 1955–2020:: the impact of large-scale sediment management

In the Western Scheldt estuary, like in many estuaries, safe navigation, flood protection, and ecological targets require a balanced and sustainable sediment management. A thorough understanding of the morphodynamic functioning of the estuary and its response to changes in hydrodynamics (natural sediment transport) and large-scale interventions...

Understanding sediment bypassing processes through analysis of high-frequency observations of Ameland Inlet, the Netherlands

Ameland inlet is centrally located in the chain of West Frisian Islands (the Netherlands). A globally unique dataset of detailed bathymetric charts starting in the early 19th century, and high-resolution digital data since 1986 allows for detailed investigations of the ebb-tidal delta morphodynamics and sediment bypassing over a wide range of...

Numerical modelling of erosion rates, life span and maintenance volumes of mega nourishments

Mega-nourishments, aiming at providing long-term coastal safety, nature qualities and recreational space, have been applied recently at the Holland coast and are considered at various other places in the world. Methods to quickly evaluate the potential and lifetime of these coastal mega nourishments are therefore very much desired, which is...

Storm Impact on Morphological Evolution of a Sandy Inlet

Observations of waves, currents, and bathymetric change in shallow water (<10-m depth) both inside and offshore of a migrating inlet with strong (2–3 m/s) tidal currents and complex nearshore bathymetry show over 2.5 m of erosion and accretion resulting from each of two hurricanes (offshore wave heights >8 m). A numerical model (Delft3D...

Towards a coupled morphodynamic model of the nearshore zone and the beach at the Sand Engine: Combining waves, tide, morphodynamics and aeolian sediment transport into a process-based model

Morphodynamic models are widespread in coastal engineering practice and indispensable to predict the effectiveness of (large-scale) sandy interventions. These models enable quantification of the effects on enhanced safety against flooding and on environmental impact over time, based on physical processes such as hydrodynamics and sediment...

Sediment- and morphodynamics of shoreface nourishments along the North-Holland coast

The Dutch coastal maintenance policy which was implemented in 1990 aims at fighting structural erosion by nourishing sand. Initially, the beaches were nourished. The lifetime of these beach nourishments turned out to be relatively short (~2 yrs), especially at identified erosion ‘hotspots’ along the North-Holland coast (e.g. Egmond aan Zee)....
