  • The effects of nourishments on autonomous coastal behaviour

    Auteurs: Spek, A.J.F. van der; Elias, E.P.L. (2013)

    Dynamic preservation of the coastline with sand nourishments is successful in The Netherlands. It stops the structuralerosion of the coast and increases the coastal sediment volume. The latter results in progradation of the shoreline andthe upper shoreface. Nourishing the shoreface has become common practice since 2001. Shoreface nourishments areplaced at the location of the outer bar or on its seaward side when present. Shoreface nourishments of volumes largerthan c. 1 million m3 will have dimensions comparable to that of natural breaker bars and will interact with them,changing their natural behaviour. They will block the net offshore migration of the natural bars. Moreover, thenourishment bodies can connect to the lateral natural bars, resulting in bar switching and extra inner bars. Finally, theaddition of extra sand volumes stabilizes the outer bar for years.

  • Improved modelling of wave-current interaction in SWAN

    Auteur: Westhuysen, A.J. van der (2010)

     Recent hindcast studies in the Amelander Zeegat tidal inlet in the Dutch Wadden Sea have shown the significant influence of currents on the prediction of wave fields by the spectral wave model SWAN. In following current, observations aretypically well reproduced, but under strong opposing current, wave heights are significantly overestimated.

  • Basal reinforced piled embankments in the Netherlands : field studies and laboratory tests

    Auteurs: Eekelen, S.J.M. van; Bezuijen, A. (2012)

    This paper summarizes the basic idea of geosynthetic reinforcement (GR) design, considering vertical load only. Two field studies are presented and the results of these measurements are summarized. This leads to the purpose of a model experiments series. After describing the tests, the most important conclusions of the experiments and the field studies lead to suggestions for the modification of the CUR 226 calculation model.

  • Restoration of freshwater lakes

  • Improvements in spectral wave modeling in tidal inlet seas

    Auteurs: Westhuysen, A.J. van der; Dongeren, A.R. van; Groeneweg, J. (2012)

    The performance of the spectral wind wave model SWAN in tidal inlet seas was assessed on the basis of extensive wave measurements conducted in the Amelander Zeegat tidal inlet and the Dutch Eastern Wadden Sea, as well as relevant data from other inlets, lakes, estuaries and beaches. We found that three aspects required further attention.
