  • Sand Engine : background and design of a mega-nourishment pilot in the Netherlands

    Auteurs: Mulder, J.P.M.; Tonnon, P.K. (2010)

    Coastal policy in the Netherlands is characterised by three scale levels. The smallest scale is aimed at the preservation of safety agaisnt flooding by maintaining a minimum dune strength the middle- and large scales at preservation of sustainable safety and of functions in the coastal zone by maintaining the coast line, respectively the sand volume in the coastal foundation.

  • Total engineering geology approach applied to motorway construction and widening in the Netherlands - part I : a pragmatic approach

    Auteurs: Ngan-Tillard, D.; Venmans, A.A.M.; Slob, E. (2010)
    Gepubliceerd in: Engineering geology : an international journal, volume 114 (2010) nummer 3-4, pagina 164-170

    The current practice of site investigation for motorways in soft soil areas like the Western Netherlands can be described as an ‘engineering approach’ rather than an ‘engineering geology approach’. After a highlight of the engineering geological concerns related to building line infrastructures on soft soils, the Dutch practice of site investigation is critically reviewed. Then, a new pragmatic methodology is suggested. It combines 1:50 000 lithostratigraphical models of the subsurface, archived geological and geotechnical data, airborne laser surface altimetry data, walk-over survey observations, and low cost geoelectric and electromagnetic data, in that order. A conceptual model is produced that breaks down the subsurface into terrain units, formations, members, and types and highlights expected heterogeneities. Ground heterogeneities are then classified based on their mapped geology and geomorphology, surface altimetry and, geophysical signatures. Cone Penetration Tests are ordered to map a limited set of representative heterogeneities. The complete profile of all heterogenieties is obtained by matching geological, geophysical and, altimetry signatures with the reference set. In a companion paper, this new methodology is applied to motorway widening on the tidal deposits of the Western Netherlands.

  • Using biological effects tools to define Good Environmental Status under the European Union marine strategy framework directive

    Auteurs: Lyons, B.P.; Vethaak, A.D. (2010)
    Gepubliceerd in: Marine pollution bulletin : the international journal for marine environmentalists, scientists, engineers, administrators, politicians and lawyers, volume 60 (2010) nummer 10, pagina 1647-1651

    In this article the combined approach of monitoring chemical contaminant levels and measuring biological effects relating to the effect of pollutants, is discussed with respect to assessing the Good Ecological Status (GES) across European marine regions. The minimum standards that biological effects tools should meet if they are to be used for defining GES in relation to Descriptor 8 of the Marine Strategy Framework Directive (MSFD) are outlined. The current international initiatives underway to develop assessment criteria for these biological effects techniques are described.

  • Over onzekerheid en duurzaamheid in de geotechniek

    Auteur: Barends, F.B.J. (2009)

    Ter ere van Keverling Buisman (1890-1944), de Nederlandse pionier van de grondmechanica, en vanwege het 60-jarig jubileum van de KIVI-Geotechniek werd op de Geotechniekdag 2009 een voordracht gehouden, die ingaat op de historie van de grondmechanica in Nederland, op de karakteristieke onzekerheden in het vakgebied en hoe daarmee om te gaan, en op de maatschappelijke waarde van duurzaamheid in en van het vakgebied. Immers, onzekerheid verkleinen is duurzaam zijn.

  • A history of futures : a review of scenario use in water policy studies in the Netherlands

    Auteurs: Haasnoot, M.; Middelkoop, H. (2012)
    Gepubliceerd in: Environmental science and policy, volume 19-20 (2012), pagina 108-120

    The future of human life in the world's river deltas depends on the success of water management. To deal with uncertainties about the future, policymakers in the Netherlands have used scenarios to develop water management strategies for the coastal zone of the Rhine–Meuse delta. In this paper we reflect on six decades of scenario use in the Netherlands, and provide recommendations for future studies. Based on two criteria, ‘Decision robustness’ and ‘Learning success’, we conclude that (1) the possibilities for robust decisionmaking increased through a paradigm shift from predicting to exploring futures, but the scenario method is not yet fully exploited for decisionmaking under uncertainty; and (2) the scenarios enabled learning about possible impacts of developments and effectiveness of policy options. New scenario approaches are emerging to deal with the deep uncertainties water managers are currently facing.
