The Hollandsche IJssel plays an important role in the freshwater provision of the province Zuid-Holland. Consequently, for Rijkswaterstaat it is key that salt intrusion is minimal in the Hollandsche IJssel. Recent studies noted that salt intrusion in the Hollandsche IJssel is limited due to a phase difference between tidal velocities in the main...

In this study the contribution of the low-frequency residuals to the sea-level variability has been examined. This is done using 106-year old sea-level record obtained at Hoek van Holland. Computing the mean sea-level per season each year and the corresponding standard deviation one finds an increase in both these features of the sea-level...

The amount of suspended sediment spill released during dredging activities in the Fehmarnbelt strait is monitored along the excavated trench to prevent negative effects on local ecology. Stratification due to the interaction of saline water from the North Sea and fresh water from the Baltic Sea forces bi-directional flow of the layer above and...

Two current assumptions of the Zeesluisformulering (ZSF) regarding a homogeneous lock density and instantaneous shipping are tested against refined descriptions according to literature: a stratified lock density and shipping according the continuity approach. These are implemented into a conceptual model constructed in Python, after which...

In recent years, several logistic optimisation models have emerged as powerful tools to assess and optimise the planning, costs, and workability of marine operations. Nevertheless, these models often rely on two underlying assumptions: (1) the significant wave height and peak wave period adequately describe (directional) wave fields, and (2)...

Key points:- Pre-closure salinity intrusion into Haringvliet-Hollands Diep is known to have reached Biesbosch National Park at flood tide. Post-Delta21 salinity intrusion is projected to be less extensive than pre-closure. Maximum intrusion is estimated to reach the westernmost Moerdijk ports mainly due to diminished tidal...

Wegman, Tess (author)
Due to climate change and human interventions, saltwater intrusion is becoming a topic of increasing concern worldwide. Salt water intrudes into the Rotterdam Waterway (RWW) by an exchange flow, where the denser sea water propagates landwards at the bottom. The main competing mechanism for this stratified exchange flow is...

TheAmazon-Orinoco river plume is a buoyant freshwater lens of 1.2 × 10<sup>6</sup>km<sup>2</sup>, which has been traced over 2000 km from the Amazon river mouthinto the Caribbean Sea and along the Lesser Antilles. The river plume iswarmer than the surrounding open-ocean waters, with temperaturedifferences up to 1.5 ∘C caused...

Phenomena like sea level rise, global warming and erosion together contribute to increasing flood risk in vulnerable coastal areas. As this flood risk increases, initiatives to mitigate the effects of climate change in the coastal zone are also increasingly sought. During recent years, the view that these measures should be circular has gained...

The Rhine Region of Fresh Water Influence (ROFI) is a shallow frictional river plume in front of the Dutch coast. Each tidal cycle a new tidal plume front with fresh-water is released. Recently, internal gravity waves have been observed in this plume. Using a Froude number analysis, support for the internal wave generation mechanism by a tidal...

This thesis introduces a new algorithm for optimising shipping routes within a dredging project. Highly dynamic and time-dependent hydrodynamic features influence shipping routes. Due to the complex interactions between the horizontal tide, vertical tide, stratifying forces, wind-driven forces, and limited water-depth, shipping routes were...

This Master thesis presents an improved model for the transport of fine suspended sediment (SPM) in the Rhine region of fresh water influence (ROFI) and in the Port of Rotterdam. It is known that the transport of SPM in the Rotterdam harbor depends on marine as well as fluvial processes. SPM transport inside the harbor has been modelled in the...

In this report a first assessment is made of the impact of hurricanes on Saint Martin. Two bays at the east coast of Saint Martin, Baie Orientale and Baie de L'Embouchure, are studied under the conditions of hurricane Irma and Maria, which both have passed over in September 2017. During these hurricanes the bays were exposed to large wind speeds...

Globally, at each river mouth freshwater is discharged to coastal waters. At each river mouth a freshwater plume is formed. These fresh water plumes are also known as the regions of freshwater influence (or ROFI’s). Furthermore, the freshwater plume will affect local coastal water levels. In order to improve global flood forecasting, research on...

This study aims for a better understanding of the sediment pathways in San Francisco South Bay (South Bay). Many issues relevant to the Bay Area community such as shipping, recreational and commercial fishing, habitat restoration, human health, and environmental water quality are reliant on understanding sediment pathways (McKee et al. [2006])....

Four kilometers west of the Norwegian island Fedje, mercury, leaking from the U-864 wreck, has highly polluted a seabed area of approximately 40 000 m2. The bow section of the wreck is located on a stability critical slope of 15 degrees. In 2016, Van Oord used a flexible fall pipe system to install a counter fill to stabilize the wreck and...

Around the world, areas with unique ecosystems are prone to harmful factors deteriorating their environment. Management of these areas need knowledge on the ecological status of these areas, to make decisions for future problems. They need easily accessible information on indicators describing the conditions of these areas. Obtaining this...

Additional thesis - The Rhine river outflow has a major impact on the North Sea in front of the Dutch coast. It creates the Rhine ROFI (region of freshwater influence), a very complex three-dimensional volume of water with a relatively low salinity. Many researches have been conducted on this phenomenon. Now another complex factor is added: a...

This thesis investigates the origin of observed current velocities at the Gemini offshore wind farm in 2015. Currents have been measured of 1.2 m/s while, based upon tidal and storm predictions, currents of only 0.7 m/s were expected. The aim of this research is to gain insight into the origin of these higher currents, taking into account the...
