Dupuits, E.J.C. (author)Dredge plumes and ecology have become increasingly intertwined in recent history; one of the more prominent reasons behind this is the influence of clouds of fine sediments released in the open water due to dredging (`dredge plumes') on for `sensitive receivers' such as coral, seagrass and mangroves. An Environmental Risk Assessment (ERA) in...master thesis 2012

Krom, J.C. (author)This thesis focuses on wave overtopping at rubble mound breakwaters with a non-reshaping berm. The research was aimed at gaining insight into the influence of a permeable berm on the overtopping behaviour. Moreover it was desired to validate existing prediction methods for the spatial distribution of overtopping for breakwaters with a non...master thesis 2012

Weij, D. (author)Bedforms play an important role in the sediment transport of a river. Because of their importance many experiments have been carried out to better understand bedforms. Most experiments concern transverse bedforms (with crests aligned perpendicular to the flow direction). However, bathymetry measurements show many instances of oblique dunes....master thesis 2012

Jiang, B. (author)The objective of this project is to assess the influence of suspended sediment on hydrodynamic properties in the study area from tidal damping aspect. Firstly, through conducting tidal amplification factor analysis based on real time measured data, seasonal variation in sloping tendency has been observed. The difference in sloping tendency...master thesis 2012

Disco, M.J. (author)Breakwaters are used for reducing wave height in harbours or divert sediment. One of the types of breakwaters is the rubble mound breakwater. These structures are constructed with smaller quarry rock as core and larger quarry rock as outer layer. For economical reasons, the design allows some damage to the armour layer. The amount of damage is...master thesis 2012

Papadopoulos, D. (author)Scour formation at the toe of a rubble mound breakwater can lead to abrupt failure. Nowadays, counteraction of scour via geometrically closed filter rules, geotextiles or combinations is the common practice. Alternatively, in specific cases the use of geometrically open filters can save significant amount of time and decrease constructional...master thesis 2012

Tusinski, A. (author)Mangrove forests have been proven to be an efficient system in attenuation of the wave energy. Therefore, they may be incorporated in the construction of coastal dikes and contribute to decreasing the total cost of such a project. This may be achieved by lowering the dike crest, lesser usage of the land or applying softer revetments. Each...master thesis 2012

Toh, H.L. (author)Light is attenuated by materials present in the water column by scattering and absorption. The knowledge of light attenuation and its contributing factors influencing visibility/turbidity is unknown in Singapore waters. This MSc thesis consists of field measurement, laboratory experiment and numerical modelling in 3 parts; parameterisation of...master thesis 2012

Spaargaren, T.N. (author)Introduction The popularity of monitoring dikes with sensor techniques is rising. It is claimed that sensor techniques lead to significant cost savings and can predict an upcoming dike collapse. But a technical foundation to use the sensor monitoring information in flood safety assessment is lacking. This research investigates the contribution...master thesis 2012

Mellink, B.A. (author)The design formula for rubble mound breakwaters by Van der Meer has an unclear Notional Permeability term. This term causes a lot of confusion for designers. In the past many people have tried to derive a better formulation for that term by experimental and analytical research. The goal of this study was to obtain a better formulation along a...master thesis 2012

Lendering, K.T. (author)New container ports are mostly constructed on low lying coastal areas or in shallow coastal waters. The quay wall and terminal yard are then raised to a level well above mean sea level to insure safety against inundation. The resulting ‘conventional terminal’ requires large volumes of good quality fill material often dredged from the sea which...master thesis 2012

Wagner, W. (author)Introduction Floods are a threat to millions of people who live in lowlands like the Netherlands. Therefore the Dutch government has been given re-quirements for primary flood defence systems like dikes. The current condition of most of these dikes does not fulfill to these requirements based on flood risk analyses of RWS. The most logical step...master thesis 2012

Reijmerink, S.P. (author)Volgens de Waterwet dienen elke zes jaar de Hydraulische Randvoorwaarden (HR) te worden vastgesteld. De HR bestaan uit hoogwaterstanden en golfrandvoorwaarden voor de toetsing van waterkeringen gegeven overschrijdingskansen welke in de wet zijn vastgesteld. Ook voor waterkeringen in havens en afgeschermde gebieden dienen de HR vastgesteld te...master thesis 2012

Wolters, H.J. (author)A committee of Civieltechnisch Centrum Uitvoering Research en Regelgeving (CUR) is currently (2012) working on the update of the handbook Quay Walls (CUR 211). In the past the partial safety factors in this book were derived using a spring model, but new developments enable to use Finite Element Methods (FEM) to model sheet-pile structures and...master thesis 2012

Schlooz, G. (author)This study investigates the hydrodynamics at a convex coastline. The Sand Engine, a man made peninsula in the Netherlands, is used as a case scenario. It is hypothesized that a rip current can develop under certain wave conditions due to the change in coastline orientation. The main goal of this research is to obtain a better understanding of...master thesis 2012

Van der Ven, P.P.D. (author)A moored vessel can experience large motions when agitated by waves. As a result, mooring lines risk breaking, the ship becomes a dangerously uncontrolled object, but most importantly unloading and loading the ship is made impossible. From an economic perspective, it is thus important to determine vessel motions due to waves at a berth. A...master thesis 2012

Den Bieman, J.P. (author)Barrier islands are important features in the coastal zone, among others because they shelter the mainland from waves and storm surge. Thus, the degradation of barrier islands can pose a threat to coastal safety. Hence, there is a societal demand for understanding and predicting barrier island evolution. High energy events, such as storms and...master thesis 2012

Siteur, W.J. (author)Embedding of subsea pipelines for protection purposes is usually done in a ‘Trench – Install – Backfill’ operation. The pipeline can also be embedded after it is installed on the seabed. This method is called post-trenching. When using a trailer suction hopper dredger for post-trenching, a large water jet erodes the soil underneath the pipe...master thesis 2012
