Compensation Grouting in Sand: Experiments, Field Experiences and Mechanisms

This thesis reports on experimental research on compensation grouting in sand. It is investigated in model tests, how the shape of the grout bodies made during injection depends on the grout properties, the density of the sand and the way the tubes are installed. The shape of the grout body affects the necessary injection pressure and whether...

Greening Governance: An Evolutionary Approach to Policy Making for a Sustainable Built Environment

After twenty years of sustainable building policies, the issue of environmental impact of buildings and urban environments remains. Policy makers still have difficulties addressing the ambiguous, contested and dynamic goals encapsulated in the term ‘sustainable development’. How to decide between using zinc or PVC gutters, when knowledge and...

Anticipatory water management: Using ensemble weather forecasts for critical events

Day-to-day water management is challenged by meteorological extremes, causing floods and droughts. Often operational water managers are informed too late about these upcoming events to be able to respond and mitigate their effects, such as by taking flood control measures or even requiring evacuation of local inhabitants. Therefore, the use of...

Hybrid models for hydrological forecasting: Integration of data-driven and conceptual modelling techniques

This book presents the investigation of different architectures of integrating hydrological knowledge and models with data-driven models for the purpose of hydrological flow forecasting. The models resulting from such integration are referred to as hybrid models. The book addresses the following topics: A classification of different hybrid...

Dune erosion during storm surges

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...

Risk, Territory and Society: Challenge for a Joint European Regulation

In 2004, the Major Accidents Hazards Bureau of the Joint Research Centre of the European Commission launched the “Land Use Planning Including MAHB and NEDIES” research programme, in the context of which most of the research collected in this book was conducted. The focus of the investigation was on the different methods developed by Member...

Rejection of organic micropollutants by high pressure membranes (NF/RO)

The presence of numerous organic micropollutants, such as pharmaceutically active compounds (PhACs) and hormones, but also pesticides and industrial pollutants, in the sources for the drinking water supply, are a big concern for drinking water utilities. Even though not all pollutants are harmful to human health, less is known about the...

Rapid load testing of piles in sand: Effect of loading rate and excess pore pressure

Settlement during vibratory sheet piling

During vibratory sheet piling quite often the soil near the sheet pile wall will settle. In many cases this is not a problem. For situations with houses, pipelines, roads or railroads at relative short distance these settlements may not be acceptable. The purpose of the research described in this thesis is to develop a model that is capable of...

Discolouration in drinking water systems: A particular approach

The quality of drinking water in the Netherlands meets high standards as is annually reported by the Ministry of Housing, Spatial Planning and the Environment (VROM)(Versteegh and Dik, 2006). Also the water companies themselves report in the voluntary Benchmark that water quality is one of the least discriminating factors as all the companies ...

Modelling hydrological response at the catchment scale: Applications and extension of the Representative Elementary Watershed (REW) approach

The characterisation, improvement and modelling aspects of Frost Salt Scaling of Cement-Based Materials with a High Slag Content

Blast furnace slag cement concrete is used extensively in a number of countries. In comparison with OPC, it is particularly well known for its excellent performance in marine environments. One dis-advantage of slag cement is its vulnerability to scaling under the combined load of freezing-thawing and de-icing salts. The current investigation was...
