Chile is heavily dependent on international trade, making its port infrastructure crucial for its economic development. Projections show that container freight demand is growing rapidly. To cope with the growing demand, an expansion for the port of San Antonio has been proposed. However, current expansion plans have faced opposition due to...

The Delta21-project is a proposed alternative solution to the increasingly higher risk of flooding in the southwestern delta of the Netherlands. Located at the mouth of the Haringvliet, it has three main ambitions: flood protection, storage of renewable energy and the recovery and preservation of nature. Flood protection is achieved by the...

Since the Brouwersdam was built as part of the Delta plan, the Grevelingen outer delta undergoes large-scale morphological changes. These changes led to the formation of a shoal adjacent to the dam, which is referred to as the Brouwersdam beach. The beach has been eroding and shifting towards the northeast ever since. The beach has no safety...

This report investigates the long-term morphological changes caused by the DELTA 21 project at the northern side, including the large scale morphological development with Delft3D model and at local scale the coastline deformation with UNIBEST-CL model. The necessity of the layout design improvement of DELTA 21 is analyzed by comparing different...

To counteract the effect of climate change, a global agreement was put into force in 2016, aiming to limit the increase in average global warming and reduce greenhouse gas emissions. In that respect, European countries are investing in cleaner sources of energy and predominantly offshore wind, which has seen a rapid growth over the last years....

Introduction and Problem Description: The autonomous nearshore morphodynamics along the Nags Head shoreline are characterized by consistent erosional behavior. The use of shoreface nourishments to counteract this erosion along shorelines has received considerable attention in the past, having the advantage of reduced cost compared to beach...

Mega-nourishments, aiming at providing long-term coastal safety, nature qualities and recreational space, have been applied recently at the Holland coast and are considered at various other places in the world. Methods to quickly evaluate the potential and lifetime of these coastal mega nourishments are therefore very much desired, which is...

Since 1990, the Dutch coastline is maintained within the ‘Dynamic Preservation’ program, according to which the coastline is maintained seawards from a reference line, mainly by applying nourishments. Research into the maintenance of the Dutch coast is continuous and causes the content of the coastline preservation program to change constantly...

Shore-normal breakwaters are constructed in coastal zones both for beach protection (erosion reduction) and port development (wave sheltering). These breakwaters have an effect on the waves, the (wave-driven) currents and hence, the sediment transport along the coast. The waves and tide force an equilibrium sediment transport along the coast in...

As a result of increased economic development in Colombia, the pressure on the natural system has increased. The export of natural resources through international ports at both the Pacific Ocean and Caribbean Sea causes conflicts between infrastructure and the dynamic behaviour of the coastal system. This Master Thesis focusses on the bay...

Nearshore sandbars have a lifetime of many years, during which they exhibit cyclic, offshore directed behaviour with strong alongshore coherence. A bar is generated near the shoreline and grows in height and width while migrating offshore, before finally decaying at the seaward limit of the surf zone. It may take 10 to 15 years for a bar to...

Inter-annual bar dynamics may vary considerably across sites with very similar environmental settings. In particular, the variability of the bar cycle return period (Tr) may differ by a factor of 3 to 4. To date, data studies are only partially successful in explaining differences in Tr, establishing at best weak correlations to local...

Durban is located on the east coast of South Africa in the province of KwaZulu-Natal. It is one of South Africa’s biggest cities and has one of the busiest ports in Africa. To maintain Durban’s current economic position the Durban Port has to expand, which is problematic due to a lack of space. A solution is to develop a completely new port: the...

Recently, nourishments have been carried out on a large scale to counteract the on-going erosion along the Dutch Coast. The main advantage of these large beach extensions is that large stretches of coastline are protected for a long time scale (e.g. 20 years), which decreases the frequency of nourishing significantly. This is not only cost...

A variety of uncertainty sources are inherent in process-based morphodynamic modelling applications. There is an increasing demand for the quantification of these uncertainties. This contribution introduces a probabilistic-morphodynamic (PM) modelling framework that enables this quantification. The PM modelling framework provides a systematic...

The longshore sediment transport (it will be referred also as LST) is a core issue in the field of coastal engineering. It is among the most important nearshore processes that control the coastal morphology, and determines in large part whether shores erode, accrete, or remain stable. Consequently, it is important to be able to calculate the LST...

Deltares is currently involved with multiple Angolan companies to advice on several coastal projects along the Angolan coast, especially in the Luanda area. Luanda is expanding rapidly trying to keep up with its economic growth as such coastal projects like land reclamation occur often these days. Still there is little understanding of the...

Input reduction is imperative to long-term (> years) morphodynamic simulations to avoid excessive computation times. Here, we discuss the input-reduction framework for wave-dominated coastal settings introduced by Walstra et al. (2013). The framework comprised 4 steps, viz. (1) the selection of the duration of the original (full) time series of...

Longshore sediment transport (LST) is one of the main drivers of beach morphology. Bulk LST formulas are routinely used in coastal management/engineering studies to assess LST rates and gradients. However, there is still great uncertainty in LST estimation with these bulk formulas. This uncertainty may have two sources: 1) experimental errors in...

Large parts of the Danube Delta coast suffered severe erosion during last decades due to both natural trends and human interventions. To investigate and quantify the processes controlling the Danube Delta coast evolution a systematic approach was employed. First, a hindcast of the wave climate was simulated using the numerical model SWAN and...
