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...

Improving XBeach non-hydrostatic model predictions of the swash morphodynamics of intermediate-reflective beaches

A very common observation is the episodic erosion of beaches during storms and the slow recovery (accretion) afterwards (Yates et al. 2009). Morphodynamic models parameterize physical processes in order to relate the fluid motions (hydrodynamics) to the bed level changes (morphodynamics) over a wide range of spatial and temporal scales. Despite...

The influence of the Sand Engine on the sediment transports and budgets of the Delfland coast: Analysis of bi-monthly high-resolution coastal profiles

The Sand Engine is a new innovation in coastal protection, a mega feeder nourishment. This pilot project was constructed in 2011 along the Delfland coast, which is historically prone to erosion. Since its construction, the Sand Engine is intensively being monitored to track the morphological development.<br/><br/>The objective of this thesis is...

The economic risk for inland water transport due to uncertainty in morphodynamic behaviour

River systems are vastly changing environments, not only due to natural process, but also human intervention plays an important role. With the many different river functions at play, large amounts of maintenance budgets are associated with river management. For decision makers it is important to know expected costs or losses and the spread...
