Drieman, R. (author)The coast of Bulgaria is subject to erosion. Because of this fact, around the town of Balchik, which is situated on the Black Sea coast, almost no sandy beaches are present. Last years there have been vast tourist developments in and around Balchik. Because of these developments, the province demands solutions to adapt coastal protection...master thesis 2011

Van der Wel, M. (author)The Port of Leixões is located in the north of Portugal. The operational conditions at berth “A” are affected by several factors resulting in a down-time of the berth of about 20%. In order to describe the behaviour of the moored vessel physical model tests were performed at the Faculty of Engineering University of Porto within the research and...master thesis 2011

De Lange, M. (author)The Ecobeach project is a newly invented method to defend the coast against erosion. Ecobeach is a coastal defense system based on the principle of passively draining the beach. This Thesis looks into possible morphological changes induced by the Ecobeach test at Egmond aan Zee performed by Rijkswaterstaat and BAM.master thesis 2011

Bos, M.F.M. (author)The wetlands in the Mississippi delta (USA) are drastically subsiding and eroding. Many projects and researches are ongoing to determine how this “drowning effect” of the delta can be stopped. One of the solutions that could be feasible is implementing sediment diversions in the levees of the Lower Mississippi River in order to divert sediment...master thesis 2011

Zethof, M. (author)The fresh water supply will be more under pressure, due to the predicted effects of climate change in the Netherlands. More frequent salt water intrusion during the summer semester is caused by the joint occurrence of low river discharges and the expected sea level rise. The control of external salinity is necessary to guarantee a sufficient...master thesis 2011

Lee, E.K.H. (author)In opdracht van het Recreatieschap Westfriesland werd een onderzoek gestart naar het verzandingsprobleem in de vluchthaven Wijdenes. De vluchthaven kampte jarenlang met verzandingsproblemen en er zijn diverse onderzoeken en aanpassingen uitgevoerd, maar het probleem is nog steeds niet verholpen. Door de verscherpte wetgeving in 2008, zijn de...master thesis 2011

Gatta, P. (author)Ventspil Free Port Authority has commissioned the design of a new berth capable of hosting post Panamax vessels and having a retaining height of 18.5 m. In proximity of the quay wall two sewage pipes lay on the bottom of the Venta River’s bed, which need to be combined into one single conduit with a diameter of 900 mm. In proximity of the quay...master thesis 2011

De Lange, W. (author)The environmental impacts caused by suspended sediments are an important issue in the environmental impact assessment (EIA) of dredging and reclamation projects. This thesis is restricted to provide insight into the emission of suspended sediment particles due to the release of return water. This water is used to pump dredged material to the...master thesis 2011

Van Broekhoven, P.J.M. (author)In JUMELET [2010] a method with a physical basis (so called “Volume Exchange model”) to determine the ‘notional’ permeability coefficient P was developed. The ‘notional’ permeability coefficient was previously introduced in the stability formula of the armour layer; see VAN DER MEER [1988]. In this latter study this coefficient was empirically...master thesis 2011

De Vlieger, J. (author)De Maas kent een aantal waterbouwkundige kunstwerken die het einde van hun ontwerp levensduur van 50 tot 100 jaar naderen. Het is daardoor van belang te bepalen wat de huidige conditie van de kunstwerken is om de betrouwbaarheid van de Maascorridor te waarborgen. Om de huidige conditie van de kunstwerken te bepalen, dienen de constructieve...master thesis 2011

Poortman, S.E. (author)This project focuses on studying and modelling the flow in the sailing area of the 2012 Olympic Sailing Competition, located partly in Portland Harbour and partly in Weymouth Bay, in order to provide accurate and reliable current forecasts for the Dutch Olympic Sailing Team. From literature it follows that the main flow in the area is the tidal...master thesis 2011

Schmedding, J.P.P. (author)The focus is on the numerical flow model TRIWAQ. It is developed as a hydrostatic free-surface flow model, which is currently being used by the KNMI and Rijkswaterstaat for predictions of water levels in the North Sea and Dutch estuaries. TRIWAQ has successfully been extended to the realm of nonhydrostatic modeling, TRIWAQ-NH, this allows the...master thesis 2011

Van der Zee, R.A. (author)One of the failure mechanisms of a dike is piping. A water level difference between the two sides of a dike causes a groundwater flow in the sand layer under the (clay)dike. This flow can transport sand from under the dike to the exit point of the groundwater flow. The formula of Sellmeijer is derived mathematically from the equation of...master thesis 2011

Van Wiechen, J.J.J. (author)This Master Thesis presents a numerical model analysis of the response of the Rhine ROFI on wind direction and speed. The aim of this study is to gain a further insight in the physical processes of the Rhine ROFI. Previous work on the Rhine ROFI focused mostly on tidal effects (straining and mixing) and inertial motions (earth rotation). Other...master thesis 2011

Henneveld, T.M. (author)The space in the Port of Rotterdam is getting scarce due to the growth of the port. This is the reason why the port authority shows the ambition to intensify the space in the port. The EMO-peninsula on the first Maasvlakte is one of the areas in the port where there is a lack of space. There are three companies who are based on the peninsula....master thesis 2011

Maas, G.P. (author)This thesis focuses on quay wall structures in the Port of Rotterdam. A quay wall is a soil retaining structure where ships can moore and transfer goods. Over the centuries the developments in quay wall structures have been tremendous, due to increasing ship dimensions, loads and crane designs. Next to that climate change is a hot topic nowadays...master thesis 2011

Bijl, E. (author)The erosion problem at the Senegambia area (The Gambia) is the subject of this thesis. The Senegambia area is the largest Tourism developed area which contributes significantly to the economy of The Gambia. In November 2003 Royal Haskoning has constructed a beach nourishment of 1,000,000 m3 as an erosion buffer with a lifetime of 10 to 15 years....master thesis 2011

Nagel, G.W. (author)Immersion of tunnels is an often used technique in rivers and canals. The transport of tunnel elements can be done under offshore conditions, but immersing the elements under these conditions is not common practise. The tunnel elements of the Busan-Geoje Fixed Link in South Korea were immersed in such a situation. During this process, several...master thesis 2011

Van Buuren, P.J. (author)This thesis studies cost estimation and investment decisions under cost uncertainty of large construction projects. The combination of these two topics intends to satisfy the Master’s theses of Civil Engineering at the Delft University of Technology and Quantitative Finance (Econometrics) at the Erasmus University Rotterdam. The first part...master thesis 2011

Miete, O.M. (author)In hydraulic engineering it is known that for the evaluation of the performance of a system, a probabilistic approach is preferable to a deterministic one. The essence of such a probabilistic approach is that random variability/uncertainty is explicitly taken into account. In this graduation project, this probabilistic way of looking at a system...master thesis 2011
