Climate change impacts on the stability of small tidal inlets

The coastal zones in the vicinity of tidal inlets, which are commonly utilized for navigation, sand mining, waterfront developments, fishing and recreation, are under particularly high population pressure. The intensive population concentration and excessive natural resources exploitation in these areas could lead to biodiversity loss,...

Rip Current Prediction System for Swimmer Safety: Towards operational forecasting using a process based model and nearshore bathymetry from video

Rip currents are among the most dangerous coastal hazards for the bathing public, and contribute to the highest portion of beach rescues all over the world. In order to help life guards in planning and preparing rescue resources so as to minimize casualties, information about where and when rip currents may occur is needed. This can be provided...

Natural headland sand bypassing; towards identifying and modelling the mechanisms and processes

Natural headland sand bypassing: Towards identifying and modelling the mechanisms and processes contributes to the understanding of the mechanisms and processes of sand bypassing in artificial and non-artificial coastal environments through a numerical modelling study. Sand bypassing processes in general are a relevant but poorly understood...

Multiscale physical processes of fine sediment in an estuary

This study presented in this book investigates micro- and macro- scale physical processes of a large-scale fine sediment estuarine system with a moderate tidal range as well as a highly seasonal-varying freshwater inflow. Based on a series measured, experimented and modeled results, the research highlights that (i) along-channel fresh-salt...

Modeling estuarine morphodynamics under combined river and tidal forcing

Estuarine morphodynamics are of broad importance to estuaries’ functions related to navigation, human settlement and ecosystems. Inspired by the Yangtze River estuary (YRE), this study aims to explore the impact of river discharge, tides and their interaction on long-term estuarine morphodynamics. Use is made of 1D and 2D process-based models....

Long-term process-based morphological modeling of large tidal basins

The morphology of tidal basins includes a wide range of features developing along different spatial and temporal scales. Examples are shoals, channels, banks, dunes and ripples. Coastal engineers use their engineering tools to answer questions on the processes governing the short term (< decades) development of these morphological features....

An approach towards generic coastal geomorphological modelling with applications

This thesis presents the development a generic morphological model for both structured and unstructured grid and the extension to a biogeomorphological model. For the morphological model, numerical algorithms are adjusted to adapt unstructured grid and are validated against analytical solutions and flume experiments. For the bio-geomorphological...

Modelling Morphological Response of Large Tidal Inlet Systems to Sea Level Rise

This dissertation qualitatively investigates the morphodynamic response of a large inlet system to IPCC projected relative sea level rise (RSLR). Adopted numerical approach (Delft3D) used a highly schematised model domain analogous to the Ameland inlet in the Dutch Wadden Sea. Predicted inlet evolution indicated the typical channel/shoal pattern...

Modeling morphodynamic evolution in alluvial estuaries

An approach to medium-term coastal morphological modelling

This thesis presents the development and validation of a novel three-dimensional sediment transport and morphological numerical model suitable for coastal regions. The thesis discusses the modelling of both suspended and bed-load transport of non-cohesive sediment, important aspects of the morphological updating scheme, and approaches used to...
