  • Operational modelling applications for coastal engineering : new developments

    Auteurs: Giardino, A.; Brière, C.D.E.; Reggiani, P.; Ormondt, M. van; Werf, J.J. van der (2011)

    This paper describes three different ongoing developments andapplications of operational coastal modelling systems: 1) The development of an operational model to simulate storm impact along the Dutch and Emilia-Romagna coast 2) The application of operational modelling to predict bathing water quality along the Emilia-Romagna coast (Adriatic Sea, Italy)3) Ongoing developments of operational models into enhance the safety of swimmers.

  • Training for crisis response with serious games based on early warning systems

    Auteurs: Kleermaeker, S.H. de; Zijderveld, A.; Thonus, B. (2011)

    This paper discusses serious games developed as part of a training program developed for a Dutch crisis response group, which acts during a (potential) flooding crisis. Serious games can be a useful and educational addition to the set of existing training tools. For operational crisis response groups a high match with real-time warning systems is essential. Our approach shows how to integrate both serious games and early warning systems for effective training and exercises.

  • Modeling of a mixed-load fluvio-deltaic system

    Auteur: Geleynse, N. (2010)
    Gepubliceerd in: Geophysical research letters, volume 37 (2010), pagina 1-7

    Present-day observations and classical classification schemes of alluvial deltas address channel dynamics and multiple sediment fractions. However, high-resolution physics-based mathematical models have not been applied to address formation of both fluvio-deltaic channels and diffluences and confluences, and their stratigraphy. Here, the authors present a simulated delta system under riverine forcing that shows striking similarity to its counterparts recognized in field and laboratory studies.

  • Modelling biogrout : a new ground improvement method based on microbial-induced carbonate precipitation

    Auteurs: Wijngaarden, W.K. van; Vermolen, F.J.; Meurs, G.A.M. van; Vuik, C. (2011)

    Biogrout is a new soil reinforcement method based on microbial-induced carbonate precipitation. Bacteria are placed and reactants are flushed through the soil, resulting in calcium carbonate precipitation, causing an increase in strength and stiffness of the soil. Due to this precipitation, the porosity of the soil decreases. The decreasing porosity influences the permeability and therefore the flow. To analyse the Biogrout process, a model was created that describes the process.

  • Effect of surge uncertainty on probabilistically computed dune erosion

    Auteurs: Roscoe, K.L.; Diermanse, F.L.M. (2011)

  • Estuary schematisation in behaviour-oriented modelling

    Auteurs: Rossington, S.K.; Nicholls, R.J.; Stive, M.J.F.; Wang, Z.B. (2011)

    ASMITA (Aggregated Scale Morphological Interaction between Tidal basin and the Adjacent coast) is a behaviour-oriented modelling approach which represents estuarine systems schematically. The results in this paper demonstrate a possible generic methodology to test different schematisations using simple models to characterise estuarine morphodynamics as a preliminary stage of estuary assessment.

  • Flood hazard maps in coastal areas

    Auteurs: Boers, M.; Diermanse, F.L.M.; Dongeren, A.R. van (2011)

    This paper describes a methodology for flood hazard maps in coastal areas with dunes. This methodology is applicable for situations where dune erosion and flooding after breaching of a dune row are the important flood hazards that endanger people, buildings and infrastructure. The methodology has been applied for thirteen coastal towns in The Netherlands.

  • Local deepening of large shallow peat lakes : a measure to improve their ecological status

    Auteurs: Penning, W.E.; Uittenbogaard, R.E.; Ouboter, M.R.L.; Donk, E. van (2010)
    Gepubliceerd in: Journal of limnology, volume 69 (2010) nummer 1, pagina 126-137

  • Mixed alluvial and non-alluvial bed topographies : observations, modeling and implications

    Auteur: Sloff, C.J. (2010)

    The presence of mixed alluvial and non-alluvial beds in rivers (for example exposed bedrock, clay layers, riprap or armored beds) highly influences the river orphological behavior and river functions. In many situations these non-alluvial sections only cover a limited area of the river bed (therefore interact closely with the rounding alluvial beds), or have a temporal character (e.g., remobilize during high flows). More detailed monitoring techniques, and new modeling approaches that are deploy.
