The Meuse is a river in West-Europe which rises at the Langres Plateau and flows from France through Belgium and the Netherlands. The river has always been an important shipping route, even though its navigability has been problematic in the Netherlands. To solve this problem seven weirs were constructed in the Dutch part of the Meuse. They are...

Over the past decades an increase in underground construction is observed. Deep excavations are among the structures used for underground construction. The construction of such structures often affects nearby existing structures and causes possibly even damages.<br/>The prediction of these damages is usually done by following these steps:<br/>1....

The objective of this research is to design and evaluate a new type of rolling gate for the Western lock (Westsluis) in Terneuzen, for which all sensitive and heavily loaded mechanical parts are both easily accessible and located above water. Having all mechanical parts above water not only makes them easier to inspect and maintain, but it also...

The combination of continuous sea level rise, and more frequent extreme river discharges will become a rapidly developing problem for the Rhine-Meuse delta over the course of the next century. The current Dutch delta management policy mostly revolves around the consistent improvement of the existing dikes to account for the increasing water...

According to the European Environment Agency (2016, pp. 137–140) annual mean river flow and the frequency of fluvial floods will have increased by 20% before the year 2100, in North-western Europe. It had been postulated in media in reports (De Ingenieur, 2014; „MIRT-verkenning Grevelingen”, 2012; Slootjes et al., 2010; Slootjes, 2013; Lammers,...

Summary<br/>In the twentieth century a substantial number of navigation locks were build in the Netherlands. The navigation locks built in that era mostly had a life span of 80 to 100 years. This means that in the coming years most of these locks will be in need of either renovation or replacement. Rijkswaterstaat, the administrator of most of...

In the far south of the Netherlands, the erratic river Meuse flows through the landscape. It recently flooded twice in the 1990s, causing much economical damage. Emergency measures, such as a demountable flood wall, were taken to prevent future flooding. And while this solution was to the liking of the inhabitants, the update in the flood safety...

Fibre-reinforced polymers (FRPs) are becoming a more commonly used building material in many civil engineering applications including locks. One quality of FRPs is the fact that it has a high strength to weight ratio. By applying FRPs in rolling lock gate design, the self-weight of the gate could be significantly reduced. This in turn could lead...

To protect the hinterland, flood defences are often located on the border between water and land. This same border however is also an attractive place to live, which may hamper improvement of flood protections. Closing off a tidal (river) system, especially in case of little discharge, may in this case be a logical consideration. This would...

Robustness is a hard-to-grip concept within engineering. This master thesis uses a framework to quantify the level of robustness that has been proposed by the Joint Committee on Structural Safety to assess the influence of the reliability requirement of a structural element. The lock complex at Weurt (the Netherlands) has been used for a case...

Additional thesis - The Maeslant barrier was the final piece of the Delta works which protects a large area of the Netherlands. However the present barrier seems to fulfil his function, several Dutch experts have doubts about the system. However the discussion on the Maeslant barrier not being safe enough refers mostly to future scenarios....

The possibility of multi-hazards, the occurrence of two or more (natural) hazards at once or shortly after another in the same location, can lead to an increased risk of structural damage and life loss. In the Netherlands, seismically-unprepared houses are especially vulnerable to newly expected earthquakes in the region of Groningen. These...

The Tilting Lock is an innovative solution for locations where road traffic crosses marine traffic overhead by a bridge. The occurrence of traffic jams at a bridge during the passage of vessels can be reduced by the construction of a Tilting Lock. By 'submerging' the vessels in the Tilting Lock underneath the bridge, the Tilting Lock increases...

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...

On 29 October 2012 hurricane Sandy hit the coast of New York City. This category 1 hurricane had a devastating effect: large parts of the city were flooded and the city was out of business for several days. An estimated total damage of $41.9 billion had occurred of which $5 billion in account of the metro system. The largest damage was to the...

The city of Amsterdam increases with approximately 10,000 inhabitants per year and Amsterdam-North is strongly under development attracting housing, employment and (re)creational activities. This is expected to induce a growth of 65% in pedestrians and cyclists, referred to as slow traffic. crossing the river IJ in 2025. The city ferry system,...

In recent years, in a number of projects gate drive mechanisms of navigation locks were checked or adapted for a longer service life, during which the reliability, safety and availability of the structure had to be guaranteed for an extended period. Several problems were encountered. When verifying the gate drive mechanism, it was found that the...

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...

As part of the Afsluitdijk project the discharge capacity, which is currently facilitated by two sluice complexes, is increased to cope with future sea level rise. It was decided to realise this by an innovative solution: the pump gate. The steel lifting gates, each containing three pumps, will be implemented in the existing sluice complex in...
