Bontje, L.E. (author), Gomes, S.L. (author), Wang, Zilin (author), Slinger, J (author)Institutional work offers a promising lens for understanding institutional change, focusing on the efforts of actors in creating, maintaining or disrupting institutions. In this paper, we explore the capacity of a narrative approach to provide insights on institutional work, using a case study from the coast of Sweden. We identify four...journal article 2018

Vandebroek, Elena (author), Lindenbergh, R.C. (author), van Leijen, F.J. (author), de Schipper, M.A. (author), de Vries, S. (author), Hanssen, R.F. (author)This paper presents a semi-automated approach to detecting coastal shoreline change with high spatial- and temporal-resolution using X-band synthetic aperture radar (SAR) data. The method was applied at the Sand Motor, a “mega-scale” beach nourishment project in the Netherlands. Natural processes, like waves, wind, and tides, gradually...journal article 2017

Bontje, L.E. (author), Fredriksson, Caroline (author), Wang, Zilin (author), Slinger, J (author)This paper discusses the dynamics of coastal policy change in Sweden, using erosion and beach nourishments as an example. The Multiple Stream Model is a theoretical model on agenda setting and policy change developed by the political scientist John Kingdon (1984, 2003). This paper applies Kingdon’s model in describing and explaining coastal...journal article 2016

Radermacher, M. (author), de Schipper, M.A. (author), Swinkels, Cilia M. (author), MacMahan, Jamie (author), Reniers, A.J.H.M. (author)In recent years, the application of large-scale beach nourishments has been discussed, with the Sand Motor in the Netherlands as the first real-world example. Such protruding beach nourishments have an impact on tidal currents, potentially leading to tidal flow separation and the generation of tidal eddies of<br/>length scales larger than the...journal article 2016

(author)The Sand Engine is a mega-nourishment constructed in 2011 with the purpose of replenishing the surrounding southern Dutch coast by exploiting the strength of local alongshore currents for the next 20 years. Long term monitoring of the Sand Engine depends upon remote sensing coupled with in-situ measurements due to both its large spatial and...conference paper 2013

Acehte, F. (author), Luijendijk, A.P. (author)This paper discusses the effectiveness of a mega-nourishment project. Mega-nourishment is a new technology for beach nourishment that has recently been developed. It arises as an alternative to beaches where a structural erosion problem is observed and there is the need for continuously nourishments works. A pilot project was implemented near...conference paper 2012

Overal langs de kust is de veiligheid tegen overstroming door de zee gehandhaafd. Met het bestrijden van de structurele erosie zijn de mogelijkheden voor behoud en ontwikkeling van functies in de duinen en op het strand toegenomen. Op de meeste...report 1995

Roelse, P. (author), Verhagen, H.J. (author)In the Netherlands much land was captured from the sea. At the same time however along the coast severe losses of land occurred. The main reasons were sea level rise and effects of decreasing tidal volumes of estuaries. Besides there were the local effects of shifting tidal channels and periodical movements of the coastline. Building of groynes,...conference paper 1991

(author)In the Netherlands today much attention is paid to the effect of coastal structures on the environment. In the past it was usual to quantify the effect of such a structure on its environment solely with the purpose of deciding whether that effect could imply any hazard to the structure itself (or to structures in the neighbourhood). Nowadays...conference paper 1990

When the disruption is caused by breakwaters, the longshore transport that is held back will cause accretion updrift of the breakwaters and erosion downdrift of them...conference paper 1981
