Meijers, P.C. (author)Additional thesis with a size of 10 European Credits. The increasing demand for wind energy has led to the development of more efficient wind turbines. A common way to increase the performance of wind turbines is the use of vortex generators. Vortex generators are small devices that are mounted on the turbine blade and they create a stream wise...student report 2015

Van der Horst, T. (author), Van Wijngaarden, M.J.P. (author), Wetser, A. (author), Daniels, J.A. (author), Knoop, C.J.T. (author), Rijnen, K.M.F. (author)In this report a study is carried out on the Magdalena River near the village of San Pablo, Colombia. The Magdalena River near San Pablo experiences two major issues which are related to navigation and erosion. The major problem for inland navigation is the sharp bend of the Magdalena River at San Pablo, which has too small a radius, causing...student report 2015

Rip, J. (author)A marine operations encounters downtime if its operational limit is exceeded during project execution. Accurate information about the expected downtime during a marine project is important information in the tender phase of such a project. The purpose of this thesis is therefore to give insight in the available methods for downtime analysis in...master thesis 2015

Hekstra, M.A. (author)Mixing systems are used in deep lakes to prevent blue algae from rapidly growing. Air bubbles rise from the bed, dragging water from below upwards. The resulting vertical circulation suppresses blue algae growth. However, these systems demand electricity of about 25,000 per km2 per year. The airlift promises to mix the water more efficiently,...master thesis 2015

Swart, R.N. (author)There are many locations where the accumulation of mud poses a problem. In lakes it can have a negative influence on the ecological situation and in port basins it can hinder traffic. Usually these mud deposits are removed periodically with regular dredging vessels. Looking at the continuous nature of the mud deposition and at the trend of an...master thesis 2015

Van Aarle, R.R.J. (author)This study is about the effect of outer-delta bottom topographies adaptations on salt water intrusion in estuaries. An increase in salt water intrusion is considered as problematic in a lot of estuaries in the world. Various solutions are developed in the past to reduce salt water intrusion. These solutions have also negative side effects. An...master thesis 2015

Kemper, A. (author), Van Ekdom, K. (author), Beulink, L. (author), Hendriks, M. (author)The Port of Imbituba, located in the state of Santa Catarina, Brazil, is a privately operated port in Brazil. In the past, the port has been upgraded in order to meet the future growth in the size and number of vessels. The main breakwater and the quay were elongated and the waterway was deepened. In the first six months of 2014, a large...student report 2015

Olij, D.J.C. (author)In this thesis 6 wave climate reduction methods are described and evaluated. Of these methods, 3 are commonly used in literature and 3 are machine learning methods that are adjusted so that they can be used for the reduction of a wave climate. The evaluation is executed with the use of a Delft3D model of the coast of Durban, South Africa.master thesis 2015

Brandt, J. (author), Minnee, K. (author), Kramer, V. (author), Gerrits, S. (author), Winter, R. (author)The authorities of Argentina wish to improve the accessibility of the ports located in the Río de la Plata and upstream to the Paraná River. The water depth in the Río de la Plata is very shallow and did not suffice for vessels to navigate. Therefore navigation channels have been dredged. Ship drafts have increased in time and nowadays there is...student report 2015

Van der Meer, A.W. (author)In the dimensional averaged numerical models, that are used for practicle purposes, there need to be accounted for three-dimensional processes. Amongst others a bank shear stress parameterization need to be incorperated. This master thesis focusses on the outer-bank shear stress in order to obtain a parameterization for the outer-bank shear...master thesis 2015

Rippi, A. (author)Some dike sections in the Netherlands failed to comply with the safety standards and one of the most promising countermeasures is the construction of retaining walls inside the dike. The Dutch design codes for dikes with retaining walls rely on Finite Element Analysis (FEM) in combination with partial safety factors. However, this can lead to...master thesis 2015

Dokter, J.C. (author)Large parts of the Netherlands are exposed to the threats of flooding due to the influence of high water coming from the North Sea region, due to high discharge of rivers like the Meuse and Rhine or due to a combination of North Sea water levels and river discharges. In order to cope these threats, strategies are developed in the Delta Program...master thesis 2015

Anker, J.C. (author)On the south-west coast of Namibia, diamonds were trapped during the Quaternary on bedrock platforms and in bedrock gullies. These were formed by differential erosion due to wave action. The diamonds originated from Kimberlite diamond pipes within the catchment area of the Orange River in South-Africa and Botswana. This river eroded the diamonds...master thesis 2015

Oosterlo, P. (author)In this thesis, a method was developed, with which the infragravity waves and morphological changes of a sandy foreshore are included in the calculation of the probability of dike failure due to wave overtopping. Constructing a natural foreshore in front of the dike can be an attractive and innovative method to decrease the failure probability....master thesis 2015

Van Rossum, S. (author)Rijkswaterstaat asks whether and how navigation locks can be standardized and if it could result in cost savings. This graduation work focused on finding how one could standardize one part of the navigation locks, namely the lock gate. Besides, finding an innovative idea for the lock gate was also part of the agenda. This resulted in the design...master thesis 2015

Van Schaick, S.J. (author)The overall behaviour of the tide-dominated Western Scheldt is in general well known. Its multichannel-system consists of ebb and flood channels, separated by intertidal areas; the tidal flats. The estuary shows a dynamic behaviour of erosion and sedimentation of the tidal flats. A large flow slide occurred at the tidal flat of Walsoorden in...master thesis 2015

Van Leeuwen, Y.B. (author)Maintenance dredging, as a result of port and channel sedimentation, can have a large share in overall maintenance costs of a port. A smart design can minimize the amount of maintenance dredging and thus improve the profitability of a port but also the long-term sustainability. As the preliminary design stages are often decisive for the final...master thesis 2015

Wit, E.M. (author)A recurrent challenge in the hydraulic engineering is to establish the required stone diameter for a stone protection on mild slopes, since the stability of gravel on a mild slope is not yet sufficiently covered by existing design methods. The objective of this study is to investigate the relation between the loads and the stability of stones on...master thesis 2015

(author)This report presents a study of the Malecón Tradicional in front of ‘Centro de Havana’ and ‘Havana Vieja’ in the city Havana, Cuba. The objective is to develop a sea defence solution that prevents unacceptable flooding of the hinterland and damage of the Malecón seawall. Implementing the recommended solutions reduces the overtopping sufficiently...student report 2015
