Soil slopes are generally unsaturated in which the soil-water characteristic curve (SWCC) plays an important role in its hydro-mechanical response. The commonly used Mohr-Coulomb failure criterion in saturated soil mechanics could be extended to take SWCC into account which is then able to determine the shear strength of unsaturated soil. Like...

Important engineered slopes are often heavily instrumented and their performance routinely monitored through these instruments. The evaluation of the safety of the slopes based on the monitored information is however a challenge. A systematic method is presented in this paper for evaluating the slope safety by combining multi-source monitoring...

Although a substantial amount of literature advocates the integrated collaborative design processes for construction projects, very little explicit knowledge exists about the impact of the integrated processes on project uncertainty. In contrast with construction site processes, which can in most cases be organized as a sequence of tasks...

The treatment of imprecision attracted continuous interest since the origin of probability as the science of uncertainty. As a matter of fact, probability has been developed to deal with uncertainty and the first argument supporting precise rather than imprecise probability counts on the nature of ordinary measurements. Starting from only a few...

Bio-methane is a renewable gas option that can be injected to the natural gas grids to increase the sustainability of the energy system and to deal with natural gas supply problems. However, being based on several factors such as resource availability, competition between bio-methane and electricity sectors for biogas and biomass supply, demand,...

This paper presents method and first results of a study to quantify and communicate geotechnical risk for highway construction on soft soil and large building pits associated with infrastructural works in the Netherlands. A set of easy-to-read maps will inform the end users, geotechnical consultants at the Dutch Ministry of Infrastructure and...

In this ever more complex, interconnected, and uncertain world, leadership is needed more than ever. But the literature and most leaders largely ignore dynamic complexity and deep uncertainty: only futures characterized by ever faster change, ever more (required) flexibility, and ever more scarcity (especially in terms of highly qualified human...

We sometimes encounter a case in which very small change of computation or experiment condition causes the significant difference in response when strong nonlinearity is involved. Slope failure simulation due to gravity by MPS method is performed to examine feature of uncertainty. The simulation results show that the output uncertainty is...

Current spatial planning and design practice regards urban and rural spatial systems as simple systems. The proposed design strategies are often one-dimensional, one-problem and one-solution oriented. As a consequence, they often decrease the flexibility of urban systems to cope with uncertainty and the occurrence of weather extremes. Spatial...

This paper presents an overview on how uncertainty and variability of mechanical soil properties are dealt with in offshore site investigation and presents some ideas for utilizing the reliability tools in a more optimal manner for this purpose. Two types of problems are addressed. First, how to extract the maximum amount of information from...

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...

Future price developments and availability of energy resources are uncertain. Therefore, developers of energy infrastructures will have to consider different scenarios in their planning. Moreover, the implementation of large infrastructures requires the cooperation of several actors, which adds to the uncertainty. In this paper we describe the...

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 natural gas production in the Netherlands is estimated to decline significantly in the coming 25 years. This situation has led producers to consider alternatives such as unconventional gas resources which are successfully utilized in the US and debated all over the world. However, despite the substantial initial resource estimates,...

To guarantee a safe flood defence in a changing environment, the adaptation to climate change needs to be considered in the design of river dikes. However, the large uncertainty in the projections of future climate leads to varied estimations of future flood probability. How to cope with the uncertainties in future flood probability under...

Water management in river deltas is increasingly being challenged by pressures from population growth, sea level rise, increasing variability in river runoffs, and potential climate change. Adaptation to such changes is not only determined by what is known or anticipated at present, but also by what will be experienced and learned as the future...

Unconventional gas has raised debates all over the world following its considerable contribution to the natural gas production of some countries such as the US. The Netherlands, which is a prominent gas producer in the Western Europe, also considers unconventional resources as an alternative to conventional production, which is estimated to...

Rabies is a viral fatal disease transmitted to humans mainly from dogs. Human deaths due to rabies have been increasing in recent years, especially in Africa and Asia where socioeconomic factors play an important role in the revival of the epidemic. In the current situation, it is unknown how the epidemic will evolve and which policies can...
