Wave attenuation in coastal mangroves: Mangrove squeeze in the mekong delta

This study explores the influence of the wave characteristics on the attenuation process of waves through coastal mangroves, which are threatened by the coastal mangrove squeeze phenomenon. Coastal mangrove squeeze is the phenomenon where coastal regions, even when sediment availability is sufficient, are eroding due to a lack of accommodation...

Analysis and modelling of Morphodynamics of the Yangtze Estuary

The flow and sediment transport in the Yangtze Estuary are intrinsically complex because various processes and mechanisms are involved on a large range of temporal and spatial scales. In this thesis the interaction of river discharge and tidal wave with the corresponding sediment transport in the Yangtze Estuary is investigated. The objective is...

Adoptable Coastal Remote Sensing Using Wave-field Observations: Instruments, Techniques and Application

The aim of this study is to innovate wave-based depth-inversion towards smarter and faster algorithms to be used with various remote sensing instruments for broad community use. Wave-based depth inversion describes a branch of coastal remote sensing, which uses video recordings of a wave-field to derive depths and thereby create digital maps of...

Sandy beaches in low-energy, non-tidal environments: Unraveling and predicting morphodynamics

Sandy foreshores, beaches and dunes play an eminent role in flood risk reduction in coastal areas, reducing the impact of wind waves and storm surges on the hinterland. In some areas, sandy protection is naturally present. In other coastal areas, engineering solutions are needed to provide safety. “Soft” sediment-based solutions often serve...

Crossing borders in coastal morphodynamic modelling

Sand is the second-most used natural resource behind water and will be under increasingly high demand in coming decades. One of the reasons for this is that, worldwide, sand is more and more applied to counteract beach erosion.<br/>This thesis presents new techniques in remote sensing and numerical modelling to better understand beach erosion...

Hydraulic functioning of permeable pile groins: Numerical simulation

Beach erosion, the loss of sand from a beach due to longshore and/or cross-shore sediment transport mechanisms, is a challenging problem. In order to stabilize the beach and to slow down the rate of beach erosion, the construction of hard hydraulic structures is a traditional option. Groins are one of the oldest man-made hydraulic structures...
