Analysis of embayed beach planform stability in Danang, Vietnam

This study presents an analysis of the planform stability of the complex embayed beach system of Da Nang Bay, central Vietnam. As a result of the intensification of extreme weather conditions and human activities in this area (e.g. land reclamation, river damming, and coastal structures), coastal safety as well as economic and ecological values...

Surfzone monitoring using rotary wing unmanned aerial vehicles

This study investigates the potential of rotary wing unmanned aerial vehicles (UAVs) to monitor the surfzone. This paper shows that these UAVs are extremely flexible surveying platforms that can gather nearcontinuous moderate spatial resolution and high temporal resolution imagery from a fixed position high above a study site. The rotary wing...

The influence of the under layer on the stability of single layer armour units

This thesis tests the influence of the under layer profile on the stability of the armour layer of concrete interlocking armour units. The analysis is aimed to offer insight into the influence of different under layer profiles on the stability of the armour layer. Furthermore the thesis includes a test of the design guideline of the under layer...

Fieldwork coastal engineering: Varna, Bulgaria

One of these resort areas lies in the town of St. Konstantine I Elelna, where Hotel Sirius and hotel Azalea are built very close to the waterline. These hotels are dependent on their neighbouring beaches for the attraction of tourism and for the structural safety of their buildings. Therefore, they want an estimation of the erosion of the...

Cross-sectional stability of double inlet systems

Barrier coasts and their associated tidal inlet systems are a common feature in many parts of the world. They constitute dynamic environments that are in a continuous stage of adapting to the prevailing tide and wave conditions. Commonly, these coastal areas are densely populated and (partly) as a result there often exists a strong conflict of...

The influence of basin geometry on equilibrium and stability of double inlet systems

This study investigates the influence of basin geometry on the cross-sectional stability of double inlet systems. The inlet is in equilibrium when the amplitude of the inlet velocities equals the equilibrium velocity (~1 m s-1). This equilibrium is stable when after a perturbation the cross-sections of both inlets return to their original...

Project Walvis Bay: Iintegrated approach for the long-term development of the Port of Walvis Bay

The objective of the project is to ‘develop a financially- and technically feasible development strategy for the Port of Walvis Bay, taking account of the uncertainties of future events’. As there is a high degree of uncertainty in the future demands for services, the attention is focussed on designing a development strategy that maximizes the...

Empirical relationship between inlet cross-sectional area and tidal prism: A re-evaluation

The well-known empirical relationship between the equilibrium cross-sectional area of tidal inlet entrances (A) and the tidal prism (P), first developed by O’Brien (1931), has been extensively reviewed. Our theoretical investigations indicate that a unique A-P relationship should only be expected for clusters of inlets that are phenomenological...
