Door de grote verkeersdrukte op rijksweg 12 (Den Haag- Utrecht). is het noodzakelijk geworden deze te herprofileren. Dit zal een aanzienlijke verbreding van deze weg tot gevolg hebben. Er zal een nieuwe kruising met de Gouwe nodig zijn. In dit verslag wordt gedacht aan vervanging van de huidige smalle brug door een tunnel in de vorm van een...

This thesis deals with the behaviour of sugars, particularly glucose and fructose, in alkaline media. The main aim of the investigation is to obtain a mechanistic insight into the reactions taking place in such media. Such insight is of importance with respect to (1) the various derivatization reactions of carbohydrates in an alkaline medium on...

Recently, Dutch transport policy acknowledges business travel as a category of travel which deserves explicit attention, because of its particular economie importance. In view of the very limited empirical and theoretica I understanding of business travel, an exploratory investigation was carried out. This report deals mainly with the empirical...

In this report an overview will be given of the basic properties of (suspended) clay particles. In section 2 the structure of clay minerals will be described. The forces between suspended particles (section 3) and the possible consequences of them, flocculation or deflocculation (sections 4 and 5) will be discussed next. Section 7 will deal with...

A research program was started to study the behaviour of cohesive sediments at the Delft University of Technology in 1989. As part of this project a well-provided physico-chemicallaboratory was built within the Hydromechanics Laboratory and adequate instrumentation was purchased. These new instruments and other instruments already present in the...

The rheological behaviour of three artificial muds was determined using a rotational viscometer. First some characteristics of the viscometer used were rneasured. For want of an appropriate calibration tluid, the viscosity of demineralized water was determined. The result agreed very well with what could be expected from literature. Then the...

A research project was started at the Delft University of Technology in order to study the interaction between waves as well as a current and a muddy bed. For this purpose several experiments were made on artificial clays. In the present report only flume experiments on China Clay are discussed. In the experiments made special attention was paid...

A research project was carried out at the Delft University of Technology in order to study the interaction between waves as weil as a current and a muddy bed. For this purpose several experiments were made on two artificial clays, namely China Clay and Westwald Clay. The results of the experiments on China Clay were reported by De Wit (1994). In...

More than six kilometers of rehabilitation works on sea defences at the Essequibo and West Deroerara coast of Guyana has been constructed within one year. This shows the fast construction of the riprap revetment design. The performance of the structure was good until the last month of construction when two slip failures occurred of a bout 100 m...

This paper reports on an analysis of the uncertainty in wind pressure (difference) coefficients, which are assessed on the basis of generic knowledge and experimental data rather than with a specific (wind tunnel) experiment. The analysis is carried out on time averaged pressure coefficients in a specific case, concerning a low-rise building in...

De Wit, S. (author)
In the design of low-rise buildings, wind tunnel experiments are scarcely employed to assess the wind-induced pressures, which are required e.g. for the simulation of ventilation flows or for the evaluation of the structural integrity. Instead, techniques are used, which predominandy rely on inter- or extrapolation of wind pressure coefficients,...

In order to obtain the cloud liquid water content from radar observations, a relationship between the radar reflectivity (Z) and the cloud liquid water content (LWC) must be found. In literature, empirical Z-LWC have been proposed. However these relationships ignore drizzle-sized droplets. Since the clouds were drizzling during Clare these...
