Micro-scale effects of stylolite orientation on the motion of tensile failure: A study analyzing strain fields of stylolite limestones using Particle Image Velocimetry

Many laboratory tests of samples where the rock fractures are based on<br/>meso-scale (cm) characterization of effective ‘intact’ strength parameters neglecting the microstructure effects. Understanding fracturing processes at<br/>micro-scale (mm) will require models with microstructure data. However,<br/>data is lacking on micro-scale.<br/...

Determination of REV and Effective Properties of Fluvial Depositional Systems: A feasibility study using 3D FLUMY models

Fluvial reservoirs are difficult to model due to the high permeability contrast between the sandstone bodies and the overbank deposits and the complex geometry of the permeable (sandstone bodies) and impermeable zones (overbank deposits). A set of fluvial meandering models has been generated using FLUMY. The models represent a range of Net-to...

Gas flow through methane oxidation systems: A laboratory and numerical study for optimising system design

English: <br/>Landfills have been indicated as a major methane source. Methane oxidation systems are `low technology' systems that can treat these methane emissions. Yet, methane oxidation systems are herein still sub-optimal and leave room for improvement. A numerical model was established to research the effective gas permeability ratio...

Geomechanical Characterization of the Buntsandstein including a Fracture Model

With an increased demand for renewable energy sources, geothermal developments have moved into the spotlight, including sedimentary structures. In the western part of the Netherlands, cretaceous sandstone bodies are already in use for the geothermal energy production. However, these reservoirs are generally producing water at temperatures less...

The effect of initial concentration on the consolidation behaviour of mud: A study on lake Markermeer sediment

Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...

De aankomstwijk: Hoe de Tarwewijk bij kan dragen aan de sociale stijging van immigranten - Arriving in the Tarwewijk; the upward social mobility of immigrants

Een onderzoek en ontwerrp voor een concentratie wijk, in dit geval de Tarwewijk in Rotterdam. De hoofdvraag welke wordt beantwoord is; Met behulp van welke ruimtelijke interventies kan de Tarwewijk bijdragen aan de sociale stijging van zijn bewoners, de immigranten?

Facies and permeability prediction based on analysis of core images

The present standards for core interpretation do not contain the acquisition of high resolution images from core slabs; images are taken on a very low resolution under a poor light source for administrative purposes only. The advantages of taking high resolution images and subsequent analysis of these images could be substantial and are...

The influence of core permeability on the stability of interlocking, single layer armour units

The permeability of a breakwater is of great importance for the stability of the armour layer. The influence of the structural permeability on the stability of rock armour units was already researched by Van der Meer using the 'notional' permeabiltiy. However, for single layer interlocking armour units the influence core permeability is rather...

Damage on rock slopes under wave attack

The aim of this study is the particularisation of the accuracy margins for the determination of the damage level in the experimental plan proposed by Remon Kik at his thesis for the study of Notional Permeability of breakwaters “The experimental research of the permeability factor P”. The evaluation of the proposed technique took place by means...

The use of Elastocoast in breakwater research

In this report will be explained how breakwaters can be made with the use of Elastocoast, a sort of glue. This makes it possible to fix the individual rocks, and allows repetitive tests possible with exactly the same layer properties. We made six samples of breakwater rock layers, made with Elastocoast and stones, which can be placed and tested...

Gaining a Porosity- Permeability relation by using the sandstone cuttings from the 'Delft Aardwarmte Project (DAP)'

Efficiency is becoming nowadays more and more relevant. The more efficient people can perform tasks, the better it is. This is also the case for doing research. The main purpose of this thesis is to gain a permeability- porosity relation of the Delft Sandstone using cuttings, that were gathered during exploration drilling. Cuttings are irregular...

Facing growth through permeability: 120 projects for Caracas

The accelerated growth that Caracas experienced during the twentieth century resulted in a superimposition of different urban patterns not always in proper dialogue between each other. The irregular political structure was supported by an increasingly powerful new economy which generated growth promoted by two opposite extremes. From above, the...

Clogging of permeable pavements in semi-arid areas

Urban development and consequently covering more areas by the impervious surfaces, has led to the decrease in natural process of rainfall infiltration and as a result deduction in ground water recharge. This decrease in ground water recharge has caused number of environmental concerns such as the decrease in base flow in streams and drying up of...

Specific Cementing of Reservoir Rock with Dual Permeability

The idea of this thesis is to use the technique for applications in petroleum engineering. This has been previously thought about, and the biogrouting technique has already been verified in the laboratory to work in a well (much larger pressure and temperature) (Latil e.a. 2008). The purpose of this thesis is to examine if the technique can be...

A comparison of overtopping behaviour over a permeable and impermeable crest: An insight into overtopping discharges and intensities

The purpose of this report is to investigate the differences in overtopping characteristics over the crest of a rubble mound breakwater when the crest is made either impermeable or permeable. Among numerous characteristics that are effected by a modification in the permeability of the crest, this report looks specifically into three separate...

'Territories in between': A comparative permeability study of two European regions between urban and rural - local and global

The in between city is often used to name areas which are neither urban nor rural, where “the sharp distinction between city and landscape has dissolved into an ecological and cultural continuum of a built structure between city and landscape”. Sieverts in (Huhlmann, 2007). The Thesis aims to gain a better understanding of how these territories...
