Foreign Nationals’ Liveability in the Dammam Metropolitan Area Petroleumscape

Since oil was struck at Dammam’s Oil Well No. 7 in 1938, the Dammam Metropolitan Area (henceforth referred to as ‘DMA) has undergone rapid urban expansion, in part due to the influx of foreign national oil workers. With their lifestyles differing from the local population, the urban sphere has developed to cater to their diverse demands. There...

Surface segregation in Pd-based ternary alloys: Modelling surface segregation in ternary alloys using Miedema’s model and Monte Carlo Simulations

Surface compositions play a predominant role in the efficiency and lifetime of membranes and catalysts. The surface composition can change during operation due to segregation, thus controlling and predicting the surface composition is essential. Computational modelling can aid in predicting the alloy's stability, along with designing surface...

Towards improving predictions of non-Newtonian settling slurries with Delft3D: theoretical development and validation in 1DV

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...

Experimental investigation to the settling and consolidation of dredged glacial till

In this research we studied the behaviour of dredged glacial till in the creation of a landfill. An experimental approach is used where we primarily focussed on the settling and consolidation characteristics. Till is in general a well graded, non sorted material and segregation during dredging and transportation can be expected. The aims of this...

Deposition of high density tailings on beaches

One of the biggest uncertainties affecting the operations of mine and land reclamation activities is related to tailings / slurry management, for which the processes of beach deposition play a critical role. Deposited tailings produce both sheet and channelised flow, causing varying velocity profiles which lead to differential settlement. This...

Towards a DiverCity

The ‘Arrival City’ (Saunders, 2010) describes a multicultural environment in Europe that creates opportunities and challenges at the same time (Wood, 2009). Sure enough, segregated, deprived neighbourhoods are a common outcome of this phenomenon. Often unplanned and uncontrolled social expansion characterised by primarily low-rent neighbourhoods...

Modeling of Surface Segregation for Binary Alloys in Vacuum and Gas Environments: Applied to Pd-alloys

Computational modeling offers the possibility to design alloys in a cheaper and faster way. A model for surface segregation for binary alloys in vacuum and by adsorption and absorption of gases was developed and applied. The proposed model was used in conjunction with the Miedema semi-empirical model for the calculation of enthalpies of solution...

Questioning the urban myths: In search of coexistence and integration in Athens

Dealing with segregation: Improving livability in a segregated neighborhood

Problem of segregation emerged as a side effect of the industrial society and is still a threat to the contemporary city. In cities with diverse socio-economic and ethnic population mix (Rotterdam also falls into this category), segregation can deepen feeling of inequality between the disadvantaged and the prosperous. Segregation can represent...

Urban Regeneration in a Market Oriented Decision Environment: A Deeper Understanding of the Plan-, Decision making and Development Process in a Market Oriented Approach to Urban Regeneration and its Possible Physical and Socio-demographic implications in Dutch Deprived Neighbourhoods

The Dutch government aims since the 1990s at a more market oriented approach in urban planning with different implications in terms of who benefits and loses from interventions in vulnerable places such as neighbourhoods of empowerment (krachtwijken). This policy shift and way of thinking about urban planning implicated big changes in the...

Simulating and classifying large-scale spatial sand-mud segregation using a process-based model for a tidal inlet system

Tidal inlet systems, as found in the Dutch Wadden Sea, often feature both sand and mud. Due to differences in sediment properties, sand and mud particles respond different to identical forcing conditions, like short waves and tidal currents. Because of this, sand and mud can get transported to different locations. This process is referred to by...

Private residential domains in the Netherlands: A research on the causes and effects of an increase of private neighbourhoods in urban areas

The number of enclosed residential domains (ERDs) in the Netherlands has seen a remarkable increase over the past twenty years. Roughly half of these projects are located in urban areas. This raises the question what the impact of large scale privatisation is on the city. Knowledge regarding the Dutch case is scarce. In particular, the relation...

Colonize the City: Addressing business segregation in London

The City is the historical nucleus of London. Today it is the world's primary financial district, a rigidly mono-functional part of London. It retains the structure - both urban and political - of a medieval citadel, unaccountable and closed to exterior. This project proposes a radical change of program: by adding a whole new landscape of...
