Automated sensitivity analysis approaches in system dynamics focus primarily on model parameters. Although table functions are often subjectively approximated, they do not form the focus of most sensitivity analyses. Recently, a promising approach that allows automation of sensitivity analysis on functions was proposed by Hearne (2010), but the...

The objective of this study is to make a study on dealing with uncertainty in the design of river training works. Based on this study, a method and several instruments have been developed that aim to improve a full and consistent use of a probabilistic design approach. This study is divided into three parts. The outline is rather unconventional...

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...

The aim of this paper is to provide a conceptual basis for the systematic treatment of uncertainty in model-based decision support activities such as policy analysis, integrated assessment and risk assessment. It focuses on the uncertainty perceived from the point of view of those providing information to support policy decisions (i.e., the...

The rapid development of Geographical Information Systems (GIS) has together with the inherent spatial nature of hydrological modelling led to an equally rapid development in the integration between GIS and hydrological models. The advantages of integration are particularly apparent in flood extent modelling. In this thesis, the integration of...

We present a probabilistic model of uncertainties for the two-phase flow through a porous medium. The uncertainty in the model comes from an incomplete knowledge of the saturation-dependent effective mobilities of the phases, which are consequently considered as random processes. The probability laws of these processes are derived following the...

Landfills represent a wide-spread and significant threat to groundwater quality. In this thesis a methodology was developed for the design of optimal groundwater moni-toring system design at landfill sites under conditions of uncertainty. First a decision analysis approach was presented for optimal design of groundwater monitoring sys-tems under...

Generalized polynomial chaos is known to fail for long-term integration, loosing its optimal convergence behavior and developing unacceptable error-levels. In this work, we present a time-dependent alternative of polynomial chaos in order to overcome these issues. This technique exists out of an on-the-fly reinitialization of the polynomial...

The Netherlands, like many countries in this world, face a challenging task in managing civil infrastructures. The management of vital infrastructures, like road bridges, is necessary to ensure their safe and reliable functioning. The Directorate-General for Public Works and Water Management in the Netherlands manages the structures in the...

A shift is taking place in planning culture from a rational planning approach, which is mainly about production, to a dynamic city approach which is more about the transformation and development of existing urban areas. Flexibility is a relevant subject in this. This graduation project has been aimed at developing an insight in flexibility in...

Coastal dunes protect low lying coastal areas against the sea. Extreme waves and water levels during severe storms may cause breaching of the dunes. Consequently, serious damage due to flooding and direct wave attack could occur, resulting in loss of life and property. Proper coastal management implies that reinforcement measures will be taken...

This thesis describes an approach to model development based on the concept of iterative model improvement, which is a process where by trial and error different hypotheses of catchment behaviour are progressively tested, and the understanding of the system proceeds through a combined process of modelling and experimenting. We show a number of...

Traditional methods to evaluate flood risk mostly focus on storm events as the main cause of flooding. Fault tree analysis is a technique that is able to model all potential causes of flooding and to quantify both the overall probability of flooding and the contributions of all causes of flooding to the overall flood probability. This paper...

Urban transport is facing an increasing number of problems. Innovative technological solutions have been proposed for many of these problems. The implementation of these solutions, however, is surrounded by many uncertainties—for example, future relevant developments for urban transport demand and supply, the possible consequences of these...
