Thoen, Sebastiaan (author), Tavasszy, Lorant (author), de Bok, M.A. (author), van Duin, Ron (author)An increasing amount of research is dedicated to the consideration of tour formation in freight transportation demand models. While empirical tour formation models so far have been starting from limiting assumptions about the resulting trips, we develop a generalized shipment-based model. We formulate a random utility model embedded in an...journal article 2020

Tavasszy, Lorant (author)Logistics processes underlying freight transport are changing rapidly, driven by progress in information technology and an unparalleled growth of consumer involvement in supply chains. This development is also driving change in freight transport flows, by all modes of transport. We argue that an understanding of logistics innovations is a...journal article 2020

Cheng, Yiwei (author), Arora, Bhavna (author), Şengör, S. Sevinç (author), Druhan, Jennifer L. (author), Wanner, Christoph (author), van Breukelen, B.M. (author), Steefel, Carl I. (author)Microbially mediated sulfate reduction is a ubiquitous process in many subsurface systems. Isotopic fractionation is characteristic of this anaerobic process, since sulfate-reducing bacteria (SRB) favor the reduction of the lighter sulfate isotopologue (S<sup>32</sup>O<sub>4</sub><sup>2−</sup>) over the heavier isotopologue (S<sup>34</sup>O...journal article 2020

de Lanoy, Jasper (author)During tenders in public transport, the bus network is reconsidered and adjusted. An accurate prediction of the effect on ridership is required. Due to the tender environment, time and input data are limited. This research focuses on deriving a relation between level-of-service (LOS) and ridership, and implementing this in a model suitable for...master thesis 2019

van Dam, Tim (author)The present thesis describes the development of a hybrid behavioural / process-based and wave-averaged model (XBeach Surfbeat) that successfully predicts the recovery of the subaerial beach at Narrabeen Beach, Australia, following a severe storm erosion in April 2015. Two model innovations were developed. Firstly, a behavioural model was...master thesis 2019

Kraaijeveld, Michael (author), de Gruijl, David (author), Postma, Marco (author), Roos, Stefano (author), de Groot, Daan (author), van der Meijs, Emiel (author)In this thesis, the implementation of a passive, chipless, frequency coded Radio-Frequency Identification (RFID) tag for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado river, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. The...bachelor thesis 2019

Zhou, Jianchao (author), Laumann, S.J. (author), Heimovaara, T.J. (author)Using naturally occurring processes to modify the engineering properties of the subsurface has received increasing attention from industry and research communities as they aid in the development of cost-effective, robust and sustainable engineering technologies. In line with this trend, we propose to use precipitates of aluminum (Al) and organic...journal article 2019

Thoen, Sebastiaan (author)Tour formation is a distinguishing feature of freight transportation. An increasing amount of research is dedicated to the consideration of tour formation in freight simulation models, but these tour formation models lack statistical calibration on empirical data, do not represent shipments explicitly, or focus on a narrow segment of freight...master thesis 2018

Mäder, Mäde (author)The Paleocene-Eocene Thermal Maximum (PETM) was a time of relatively abrupt climate change with intensive atmospheric greenhouse warming of 5 - 8˚C and is regarded as quasi-analogous for the modern anthropogenically-induced global warming. It therefore attracted considerable attention from geologists over the last decades. The PETM occurred 56...master thesis 2018

de Gijsel, Stefan (author)This thesis describes how the simple random walk particle model can be extended to account for sand deposition and suspension, and for particle interaction: clumping together and falling apart. The extended models are analyzed, and the corresponding partial differential equations are derived. These equations are compared to the currently used...bachelor thesis 2018

van Cranenburgh, S. (author), Chorus, C.G. (author)This paper is the first to study to what extent decision rules, embedded in disaggregate discrete choice models, matter for large-scale aggregate level mobility forecasts. Such large-scale forecasts are a crucial underpinning for many transport infrastructure investment decisions. We show, in the particular context of (linear-additive)...journal article 2018

Chorus, C.G. (author)This article highlights the importance for urban planning, of the under-researched notion of superstar destinations. Furthermore, it presents and compares destination choice models that generate a convex demand for destination quality, and thereby explain and predict the existence of so-called superstar destinations. When compared to their...journal article 2018

Khadra, W.M. (author)Coastal aquifer management has recently emerged as a main scope in groundwater hydrology, especially in arid and semi-arid zones. About two thirds of the human population are currently gathered close to shorelines relying on coastal groundwater resources. Worldwide, these systems are subject to quality deterioration due to a multitude of...doctoral thesis 2017

Hollestelle, Martijn (author)Complex urban planning problems comprise socio-spatial conditions, human behaviour and external factors (e.g. technological developments). The perspective of urban planners and designers is crucial to comprehend these problems from a holistic point of view but does not possess the skills to grapple the full problem. Cities bear characteristics...master thesis 2017

Jongedijk, Cleo (author)A very common observation is the episodic erosion of beaches during storms and the slow recovery (accretion) afterwards (Yates et al. 2009). Morphodynamic models parameterize physical processes in order to relate the fluid motions (hydrodynamics) to the bed level changes (morphodynamics) over a wide range of spatial and temporal scales. Despite...master thesis 2017

Bak, Jasper (author)Sea level rise poses challenges to the tidal inlet systems of the Wadden Sea, including the barrier islands. If no measures are taken, the shorelines of the islands will retreat and the basins may drown. In the Ameland Inlet, the Boschplaat at the eastern tip of Ameland and Bornrif at the western tip of Terschelling are currently shrinking. <br/...master thesis 2017

Rahman, M.M. (author)The principle of Subsurface Arsenic (As) Removal (SAR) is to extract anoxic groundwater, aerate it and reinject it. Oxygen in the injected water reacts with iron in the resident groundwater to form hydrous ferric oxide (HFO). Dissolved As sorbs onto the HFO, which allows for the extraction of groundwater with lower As concentrations.doctoral thesis 2017

Adjodha, Sharwan (author)The self-driving vehicle technology can be a potential game changer. The image of traffic and transport we know nowadays can change rapidly over the next twenty years with the introduction of autonomous driving. Still, there seem to be some uncertainties with the development of autonomous driving. Apart from the fact that this technology is...bachelor thesis 2017

Wittebrood, M. (author)In 2014-2015 the coastal stretch between Petten and Camperduin was strengthened by using 35 million m3 of sand. At the seaward side of the Hondbossche & Pettermer sea defence a beach and dune system was built which is called the ‘Hondsbossche Dunes’. The old sea dike has disappeared behind the new dunes and is no longer an active part of the...master thesis 2017

Halim, R.A. (author)Uncertainties in future global trade flows due to changes in trade agreements, transport technologies or sustainability policies, will affect the patterns of global freight transport and, as a consequence, also affect the demand for major freight transport infrastructures such as ports and hinterland networks. Policy makers face the challenge of...doctoral thesis 2017
