Jonkman, S.N. (author), Schweckendiek, T. (author)This paper presents and overview of advances in flood risk and levee reliability analysis in the Netherlands. It is described how new safety standards – in the form of a target failure probability – have been derived on the basis of nationwide flood risk assessments which taken into account both economic risk and risk to life. The process for...conference paper 2015

Hijma, M. (author), Van der Meij, R. (author), Lam, K.S. (author)The subsurface plays an important role when assessing flood risk and its build up has to be known in considerable detail to properly determine the chance of flood-protection failure. Currently, the subsurface below flood-protections is often characterized by geotechnical cross sections that are constructed using e.g. cone penetration tests (CPTs...conference paper 2015

Oung, O. (author), Brassinga, H. (author)A feasibility study was carried out on the redesigning of an existing quay wall of a core harbor in the Netherlands, which was more than 45 years old. The geotechnical behavior of the existing quay wall, especially because of its age, as a response to the maximum load change is undoubtedly the uncertain parameter here. The design and redesign...conference paper 2015

Nagy, G. (author), Nagy, L. (author)When it comes to flood protection, the established method is to use impermeable material in dikes, to prevent seepage. This material is usually some kind of clay soil which is considered as impermeable and erosion-resistant. Dispite that, in many occasions not only seepage, but the failure of the dam occured due to surface erosion, because these...conference paper 2015

Rodriguez-Ochoa, R. (author), Nadim, F. (author), Cepeda, J.M. (author)This paper presents an offshore risk analysis in a systematic manner to assess the influence of earthquake-induced submarine slope failure on offshore structures. The risk analysis is carried out for the future development of a natural gas field in deep waters in the south part of the Gulf of Mexico. The study accounts for all the elements in...conference paper 2015

Halter, W.R. (author)Many governments want to realize wind power, because it is a technology that promotes sustainable energy. That is why there is need for locations for wind farms (groups of wind turbines). Dikes are good locations for wind farms, because of favourable wind conditions, the absence of cultivation and the presence of road infrastructure. However,...conference paper 2015

Zhang, Y.-J. (author), Feng, X.-T. (author), Jiang, Q. (author)The epistemic uncertainty and aleatory uncertainty caused by the geology condition and construction method make the surrounding rock stability evaluation of underground cavern group difficult. The first may be reduced with more field investigation, tests or monitoring, but the later can not be avoided completely. So the risk analysis method can...conference paper 2015

Wojciechowska, K. (author), Pleijter, G. (author), Zethof, M. (author), Havinga, F.J. (author), Van Haaren, D.H. (author), Ter Horst, W.L.A. (author)The aim of this article is to present and discuss fragility curves that were derived for numerous dikes in the Netherlands within the Dike Data Service Centre (DDSC) initiative. A fragility curve of a dike is a mapping from the set of loads, acting on the dike, to the set of conditional dike failure probabilities. The DDSC is a platform around a...conference paper 2015

Maruyama, O. (author)The numerous major earthquakes in Japan, such as the Great Hanshin-Awaji earthquake, Tohoku Regional Pacific Coast earthquake caused substantial casualties and property damages. Private companies/public utility enterprises should provide disaster reduction investment as part of risk management and prepare a strategic Business Continuity Plan....conference paper 2015

Venmans, A. (author), Schokker, J. (author), Dambrink, R. (author), Maljers, D. (author), Heerema, J.J. (author)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...conference paper 2015

Baecher, G.B. (author), Christian, J.T. (author)The statistics course most engineers took in college—seldom more than one—introduced them to a particular species of statistics, which, regrettably, is of limited use in geotechnical practice: frequentist sampling theory. That species of statistical thinking arose to address problems of agricultural experimentation, biology, and economics. It is...conference paper 2015

Van Seters, A.J. (author), Spendel, K.J. (author)In The Hague, a 2 storey parking garage was built beneath a reinstated canal at the Veenkade with 160 parking places. The canal and the parking garage were installed at minimum 3 - 6 m distance from old houses with a shallow foundation by means of a 10 m deep building pit. A risk analysis was undertaken and major risks were identified, resulting...conference paper 2015

Borst, M.A. (author), Van der Hout, E. (author)A method was developed to identify areas where uplift is likely to occur during sewerage renewal. The results were presented as a map that can be used by generalist civil engineers in the early stage of the sewerage renewal planning process.conference paper 2015

Mooney, M. (author), Grasmick, J. (author), Prantil, E. (author), Thompson, A. (author)Ground, building and utility deformation monitoring is a well-accepted and required practice for underground construction works in urban environments. The availability of real-time monitoring data during construction allows stakeholders to stay ahead of potential problems, to make decisions prior to damage occurrence, and ultimately to reduce...conference paper 2015

Sundell, J. (author), Rosén, L. (author), Norberg, T. (author), Wladis, D. (author), Alén, C. (author)Sub-surface constructions generally involve drainage of groundwater, which can induce land subsidence in compressible soil deposits and cause extensive damage costs in urban areas.

Sartain, N. (author), Mian, J. (author), Free, M. (author)This paper provides recommended guidelines for communicating geotechnical risk. Geotechnical engineering in practice is the management of ground-related risks, and geotechnical engineers are good at this. However, they are often less good at communicating these risks to stakeholders who may hold very different perceptions of risk. A review of...conference paper 2015
