van der Ven, Oscar (author)This study is the first to experimentally show two wave mechanisms regarding density wave amplification with long horizontal slurry transport. There is bed-driven and suspended-driven density wave amplification, in which the grain size determines which mechanism is dominant.<br/><br/>Density wave amplification in hydraulic pipeline transport...master thesis 2023

Vehmeijer, Reinoud (author)Subsea rock installation is a process in offshore engineering where rocks are placed on the seabed or subsea structures using a fallpipe. An example of a subsea structure could be a cable or pipeline that must be protected. In this research, the main scope is rock installation for scour protection of the foundation of offshore wind turbines. As...master thesis 2022

Ma, Sebastiaan (author)The Port of Rotterdam experiences large amounts of siltation from the upstream rivers in its basins and canals every year. Furthermore, container vessels increase in size every decade and therefore require a larger navigational depth. These two factors cause the yearly amount of dredged material to increase. Currently, mainly trailing suction...master thesis 2022

Ordeman, Sam (author)Digital Soil Mapping (DSM) of soil types in geotechnical project areas is a top priority. These maps are often used in decision making and can have significant consequences related to costs and risks. Usually, these maps are generated by digital soil models that interpolate soil types at known locations. In practice, conventional spatial...master thesis 2022

Goda, Aditya (author)When a ship reaches the shore, the water depth reduces and thus the under-keel clearance also reduces. The ship keel clearance influences the maneuverability of the sailing ship.<br/><br/>In this thesis project, the link between the fluid mud rheology and its density is first investigated. The exponential relation reformulated between the...master thesis 2021

Blankenaar, Britt (author)The rising demand for minerals and metals and the depletion of land-based resources has created a renewed interest in the extraction of resources from the deep ocean, i.g., deep sea mining. This research focuses on the mining of manganese nodules, these are potato-shaped objects, 5-10cm in size, composed of metals half buried in the seafloor. A...master thesis 2020

Osejo Rodriguez, Jorge (author)Over recent years, there has been an increase in demands for rare and precious minerals worldwide. Mostly this is due to the rise of the world’s population and the drive towards a green energy transition and low carbon economy. Prices are rapidly increasing, and there is an identifiable risk of an increasing supply shortage of raw materials,...master thesis 2019

Wijnands, Jasper (author)Manganese nodules have been lying on the deep sea soil for centuries before they became known. The first ones to discover the nodules were Murray and Renard, during their scientific cruise between 1872 and 1876 (Murray and Renard, 1876). The Clarion-Clipperton Zone, located between Mexico and Hawaii, appears to have a virtually inexhaustible...master thesis 2018

Dom, Arnoud (author)In the dredging industry, centrifugal pumps are most commonly used and selected based on their operational capacities and expected slurry characteristics. The handling capacity of a centrifugal pump is however supplied for handling water and cannot be applied to other slurry conditions without an applicable correction. For handling Newtonian...master thesis 2017

Noordermeer, Bob (author)The cable between Vlieland and Terschelling needs to be replaced. The thesis focusses on the replacement of this cable. Because of the sensitive environmental situation some additional hurdles will need to be taken in order to come up with a decent placement plan.master thesis 2017

Wildenberg, M.P.J. (author)This report describes and analyses small scale plough process. This research is initiated by Deltares and the Delft University of Technology as an experimental way to gain insight in the ploughing of the river bed in rivers. The main target of this thesis is to gather information on the plough process as applied in the maintenance of the Waal...master thesis 2017

Van Es, H.E. (author)This study aims to improve the predictive capabilities of flow pattern and depositional behaviour of non-Newtonian, high concentration sand and fines mixtures. The depositional behaviour influences the geometry of the deposit and the distribution of sand and fines particles, which in turn influence the strength and consolidation performance of...master thesis 2017

De Bie, M. (author)Damen Dredging Equipment (DDE) has a quest to make their cutter suction dredger (CSD) and their DOP pump operable by everyone for every slurry type at the correct working point every time. To complete this quest, first a process status evaluating tool has to be developed which replaces the visual wear inspection. This thesis is the first step in...master thesis 2017

Helsloot, T.C. (author)Due to increasing marine traffic intensity on inland waterways the interaction between ships and banks is becoming more of a problem. Bank effects make ship manoeuvring more difficult and rivers need to be protected against ship-induced currents and waves. This thesis contributes to the development of a new method that simulates these ship-bank...master thesis 2016

Hanssen, J.L.J. (author)To date there is limited knowledge about the flow behaviour of non-Newtonian slurry and tailings flows. In hydraulic engineering and the mining industry numerous questions and uncertainties still exist. Different numerical and analytical models have been developed attempting to meet this demand. For the larger part they describe the rheological...master thesis 2016
