In dit onderzoek is aandacht besteed aan de gravitatie circulatie in de Waddenzee. Daarbij is de vraag of dit een rol kan spelen bij sedimenttransport. De gravitatie circulatie is een stroming die bovenin de waterkolom een andere stromingsrichting kent dan onderin en ontstaat doordat het water niet een uniforme dichtheid kent in het bekken....

In Walla Walla, Washington the Mill Creek flows through an outdated concrete spillway that needs renovation. The city council of Walla Walla saw this as an opportunity to further develop this channel. Their desires include conservation of the fish ladder, enabling to sail by boat and to prettify the spillway. A Sobek 1D model was built to give a...

River floods are considered one of the most important natural disasters and causes huge damages every year, both in economic consequences and fatalities. Out of historical perspectives, human settlements are located in fertile and economic attractive delta regions. Deltas tend to be constantly changing nodes of economic and urban growth leading...

Om erosie en ontgronding in rivieren te voorkomen kan bodembescherming worden toegepast. Voor stenen als bodembescherming zijn er al twee verbanden bekend tussen de stroomsnelheid waarbij de stenen instabiel worden, ofwel de kritieke stroomsnelheid, en de diameter. Deze twee verbanden zijn door de onderzoekers Izbash en Shields samengesteld....

Floods are an increasing problem all over the world. Due to climate changes and socio-economic developments multiple areas are at risk. Flood risk is nowadays expressed as the global economic losses due to floods and these losses are raising. HKV and Deltares recognized this problem and started to develop a method to calculate flood risks. A...

Door menselijke ingrepen zoals versmalling en rechttrekken van de rivier, winning van bouwstoffen en de bouw van waterwerken krijgen Nederlandse rivieren steeds minder zand en grind aangevoerd. De stroomsnelheid en daarmee de erosie nemen toe. Er ontstaan grote ontgrondingskuilen, die het risico op het bezwijken van de oever vergroten. Om dit...

Dutch flood protections are assessed every five to six years in a nationwide safety assessment round. During the last assessment round large dike stretches in the Dutch Wadden Sea could not meet the safety requirements, and were assessed with failure. Dike strengthening is therefore needed in these areas. However, in front of these dike salt...

The Netherlands are protected against extreme high waters from the sea by an ingenious system of barriers. One of the most famous ones is the Maeslant barrier in the New Waterway near the port of Rotterdam. This barrier however, is subject to discussion, as it might not function as intended, because of the following reasons. It has a very low...

The strength of the Atlantic Meridional Overturning Circulation (AMOC) will decrease due to climate change. However, the magnitude of this decrease is still under debate, since uncertainties exist about the driving mechanisms of the sinking branch of AMOC. Conceptual models have shown that sinking is located at the lateral boundaries of the...

Momentarily the determination of the static stability of rock on mild slopes can be split in roughly two paths, the empirical and the physical approach. However, both the approaches have their limitations from which one could conclude that neither approach is currently an accurate description of the stability of rock on mild slopes under wave...

To determine the nominal diameter of armour rock for a rubble mound breakwater, the ‘Van der Meer’-formula is frequently used. It requires the so-called 'notional permeability' parameter P, which has been defined for a limited number of structures. Often designed structures deviate from these defined lay-outs. To determine the notional...

This thesis report considers the topic of sustainable marina development. This term can be understood to be a combination of two terms; “sustainable development” and “marina”. Sustainable development in this research study has been considered in relation to the coastal zone and basically entails an approach to ensure a balance between the...

Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...

Although mangrove forests have proven to contribute to wave dissipation significantly, these ecosystem are threatened mainly by the expanding aquaculture. International or nationwide applied greenbelt policies are often used for the preservation of the mangroves and hence the flood hazard reduction, without taking local (hydrodynamic) conditions...

The objective of this study is to identify the mechanisms that drive the morphodynamic behaviour of the sediment disposals in the subtidal zone north of the intertidal shoal Walsoorden. The morphological development of the sediment in the subtidal zone near this shoal has been monitored and measured. The gathered bathymetric data show that one...

Navigation locks are used to transport vessels between waterways with different water levels. In the nearby future many navigation locks will be renovated or replaced. During the design of a new lock still some unknown factors are encountered. One of these factors is the vibration of the valve. The valve is part of the filling and emptying...

Bank protections are currently constructed with stone, wood, concrete and steel. NETICS has introduced a sustainable and commercially very attractive alternative called the GEOWALL. The goal of this study is to find a viable field of application within the quay structures by considering the arising challenges of a larger scale wall. Additionally...

The number of wind farms that are commissioned, being installed, or prepared is still increasing due to a growing demand for green energy. To benefit from the higher wind velocities, which can be found at sea, and to prevent the pollution of the horizon, wind farms are being built offshore and installed in an ever increasing water depth. The...
