Investigation of the sand losses which occur during construction of a closure dam in a tidal inlet

Willems, J.A. (author)

At the construction of 'Maasvlakte 2' in 2012, two sand closures were constructed. Sand is in most cases the most profiting construction material. The processes and the amount of sand losses which occur during the construction of a closure contain large uncertainties. In order to construct a closure, the production of sand has to be larger than...

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

Eelkema, M. (author), Wang, Z.B. (author), Stive, M.J.F. (author)

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...

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

Dastgheib, A. (author)

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....

Climate change impacts on the stability of small tidal inlets: A numerical modelling study using Realistic Analogue approach

Duong, T. (author), Ranasinghe, R. (author), Luijendijk, A. (author), Dastgheib, A. (author), Roelvink, D. (author)

Tidal inlets are of great societal importance as they are often associated with ports and harbours, industry, tourism, recreation and prime waterfront real estate. Their behaviour is governed by the delicate balance of oceanic processes (tides, waves and mean sea level), and fluvial/estuarine processes (riverflow and heat fluxes), all of which...

The Lagos coast - Investigation of the long-term morphological impact of the Eko Atlantic City project

Van Bentum, K.M. (author)

The Lagos coast has been suffering high rates of erosion since the construction of three harbour moles, i.e. the West Mole, East Mole and the Training Mole, at the tidal inlet connecting the Lagos Lagoon to the South Atlantic Ocean. To provide for a permanent erosion mitigation measure and to create residential and commercial area for circa 400...

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

Dissanayake, P.K. (author)

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...

Morphodynamics of seasonally closed coastal inlets at the central coast of Vietnam

Tran, T.T. (author)

Situated in a monsoon-prone humid tropical region, Vietnam is affected by both oceanic and continental climates causing disasters to the country like riverine flooding and storm induced damage. The coastal districts of Vietnam have a population of about 18 million habitants, account for nearly one fourth of the total population of the country...

Jetty design at Rio Araranguá

Van der Woerdt, W. (author), Van den Bosch, I. (author), Heerema, R. (author), Ruijs, M. (author)

Master project report. The hydraulic efficiency of the river Araranguá will be increased by the construction of jetties at the mouth of the river. The river tends to migrate from south to north which decreases the hydraulic efficiency and causes flooding upstream during events of high discharge. To stop the migration the construction of jetties...

Hydrodynamics and morphodynamics of a seasonally forced tidal inlet system

Lam, N.T. (author)

Tidal inlets along the central coast of Vietnam are highly dynamic and variable under the influence of seasonal climatic regime. The strong episodic processes of river flow and wave action cause the inlet morphologies to be changed frequently and unpredictable. Despite the interests and research on tidal inlets have been growing in recent...

Hydrodynamics and morphodynamics of a seasonally forced tidal inlet system

Lam, N.T. (author), Stive, M.J.F. (author), Wang, Z.B. (author), Verhagen, H.J. (author), Thuy, V.T.T. (author)

Hydrodynamics and morphodynamics of a seasonally forced tidal inlet system are investigated using numerical models. The ocean forcing including tidal and wave actions and sediment transport is simulated using Delft3D model. Fluvial processes in Delft3D are taken into account as results from SOBEK RURAL model. Analysis of the numerical simulation...
