The characteristics of the manometric method are investigated so that it can be used to obtain accurate data of sorption of supercritical gas in coal. Furthermore, data of the sorption of carbon dioxide, methane and nitrogen in coal at in situ conditions have been determined. Accurate data are required to develop a theory that can describe the...

Large parts of The Netherlands are protected from flooding by a narrow strip of sandy beaches and dunes. The aim of this thesis is to extend the existing knowledge of dune erosion during storm surges as it occurs along the Dutch coast. The thesis discusses: • A large scale dune erosion experiment to obtain better insight in near dune...

A Ground Penetrating Radar (GPR) survey was conducted in April of 2008, collecting 27 km of radar profiles in Sandflugtdalen, a permafrosted glacio-fluvial bedrock valley in West Greenland. Due to low electric permittivity of frozen soil, GPR has good depth penetration of permafrost, up to 80 m using low-frequency (50 MHz) antennae. Resolution...

Research performed of the last decades in the waste water treatment field has shown the ability of zeolites to adsorb ammonium via ion-exchange. Recent research has proven that zeolites might also be capable to remove the lower concentrations of ammonium present in groundwater to the for drinking water required standards. This makes it a...

The paper investigates the influence of relative bend curvature on secondary flow, energy losses, and turbulence in sharp open-channel bends. These processes are important in natural streams with respect to sediment transport, the bathymetry and planimetry, mixing and spreading of pollutants, heat, oxygen, nutrients and biological species, and...

The primary structure of the cellular wall of Shanghai Natural History Museum (SNHM) can be defined as a grid structure on a single curved surface (developable), with a cell-like configuration. The shape of the wall (surface) is defined by two free-form curves, which explicate a ruled/lofted surface. The cellular wall is one of the most...

Peat is sediment consisting of incompletely decomposed organic matter deposited in swamp and marsh. It has served for a long time as benefits for human beings. Meanwhile, it has posed huge challenges to geotechnical engineers because of its unique characteristics such as anisotropy, low stiffness, high compressibility and strong creep...

The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...

A new treatment concept for drinking water production from surface water has been investigated on a pilot scale. The treatment concept consists of fluidized ion exchange (FIEX), ultrafiltration (UF), nanofiltration (NF), and granular activated carbon filtration (GAC). The FIEX process removed calcium and other divalent cations; the UF membrane...

Forward modelling demonstrates that resistivity anisotropy has a huge effect on Multi-Transient ElectroMagnetic step and impulse responses. The earth is never isotropic – even a stack of isotropic layers behaves anisotropically – and there is a great need to ccount for resistivity anisotropy in order to delineate the true target depth and target...

Seafloor Massive Sulfide (SMS) contains high levels of metals such as copper and gold. Water depths of 2000 up to 3000 meter make mining of SMS a challenge. Despite this, mining industry encourages research into feasible extraction methods of SMS, pushed by the high metal prices nowadays. This research focuses on the influence of hydrostatic...

Building a new island? For recreational and living purposes? At first glance this seems like an impossible task due to the economical crises and the political sensitivity of the chosen location. But in fact it is this unique location and the possibility that government and private parties join forces in economical hard times that gives the...

A promising possibility to reduce corrosion resistant pipeline costs is the concept of Tight Fit Pipe, which is a double wall pipe where a Corrosion Resistant Alloy liner is mechanically fitted inside a carbon steel outer pipe. The mechanical bonding of the Tight Fit Pipe is made through a thermohydraulic manufacturing process. Problem...

In dredging works, fines are encountered in different ways. Fines can be produced during the cutting of rocks or can be found in natural deposited sand. The presence of fines in sand soil is generally recognized as problem in geotechnical engineering. It is believed that fines in a sand increases soil compressibility and tendency to creep. Also...

This thesis project is a part of Dutch project PraktijkProef Amsterdam (PPA), in which the coordinated network traffic management in the regional area is analyzed. One of control levels in the project PPA is sub-networks, where the concept of the macroscopic fundamental diagram (MFD) is applied. Unlike a conventional link fundamental diagram, an...

The construction of the North-South metro line project in Amsterdam (the Netherlands) is ongoing for the last five years and until recently suffered no major construction incidents. In the summer of 2008 two leakages occurred in one of the building pits of the deep stations. These leakages caused major settlement of a number of historical houses...

The excavation of deep building pits often requires a check against failure by uplift of low permeability ground layers below excavation level. Whenever the weight of these soil layers is less than the pore-water pressure underneath, measures to resist buoyancy are to be considered. The measures most commonly adopted include: decreasing the...

The new North/South metro line in Amsterdam contains several stations, some of which with an excavation depth of 30 m below surface. The design of these station boxes is very much determined by the adjacent historic buildings, high water table and the relatively soft soil. A lot of effort is put into minimising the settlements of buildings with...

Bed degradation in a number of Dutch river branches, like the Bovenrijn, can cause various problems in the near future. At low waters the navigation depth at the non-erodible layer near Emmerich can become too small. Other problems could be lower ground water levels and stability of structures in and near the river, like groynes. To diminish...
