Sediment Pathways on Ebb-Tidal Deltas: New Tools and Techniques for Analysis

In an era of rising seas and other challenges posed by climate change, coastal regions like the Netherlands are facing ever graver threats. Strategic sand nourishments could mitigate the threat of coastal erosion and sea level rise on barrier island coasts while limiting ecological impacts. However, insufficient knowledge of sediment transport...

Stability of intertidal and subtidal areas after Delta21 plan: Evaluating the consequences for the morphological development produced by the interventaion

In recent years, there has been an increasing need for solutions against the threats that SLR and climate change represent for coastal systems, especially in low lying areas like the SW Dutch coast. Simultaneously, awareness of the impacts that human activities have on natural environments has surged. Integrated and sustainable solutions are...

Hydraulic and morphological impact of a closure dam in the Gulf of Khambhat

Tidal basins are highly dynamic environments with a complex behavior that is often disturbed by human activities. Considering that tidal dynamics have a direct impact on surrounding engineering infrastructures, adjacent coastlines, nature environment and socio-economic human activities, it is crucial to know the impact of human interventions on...

Morphodynamics of the Haringvliet ebb-tidal delta: Unravelling the mechanisms behind its morphological evolution

<b>KEY POINTS:</b><br/>• While the formation of the intertidal shoal Hinderplaat was a direct consequence of a human intervention, its degradation was a natural response of the system to frequent hydrodynamic forcing conditions.<br/><br/>• Tidal currents push the Hinderplaat in offshore direction, but this is counteracted by waves: these...

EBB-tidal delta morphology in response to a storm surge barrier

The ebb-tidal delta of the Eastern Scheldt tidal inlet has been under the influence of a storm surge barrier for the past 25 years. This barrier caused a strong decrease in average tidal currents through the inlet. The morphological response of the ebb-tidal delta is characterized by several different processes: (1) an overall decrease in...

The influence of dredging activities on the morphological development of the Columbia River mouth

This is a numerical modelling study on the impact of dredging and disposal activities on the long-term morphological development of the Columbia River mouth (MCR). Dredging activities removed 120 Mm3 of sand from the MCR during the studied interval between 1958 and 1999. Only one-third of this volume was disposed in the active littoral zone....
