Horst, J. (author)Coastline regression is a significant threat to many coastal zones. Being able to mitigate the erosion while simultaneously improving nature development is something that is increasingly strived for in coastal projects. This report utilizes the building with nature philosophy to explore integrated solutions for a coastal erosion problem in...master thesis 2017

Bakker, S.A. (author)To help to provide a desperately needed coastal protection strategy for the Mekong Delta in Vietnam this research looks into the possibilities for natural and sustainable coastal defence systems, including mangroves and active sediment management, such as a nourishment. The coastline of the Mekong Delta suffers from severe erosion and mangrove...master thesis 2017

Hoonhout, B.M. (author), de Vries, S. (author)Mega nourishments are intended to enhance growth and resilience of coastal dunes on medium to long time scales by stimulation of natural sediment transport processes. The growth and resilience of coastal dunes largely depends on the presence of a continuous supply of aeolian sediment. A recent example of a mega nourishment is the 21 Mm<sup>3<...journal article 2017

Flierman, M.W.T. (author)River systems are vastly changing environments, not only due to natural process, but also human intervention plays an important role. With the many different river functions at play, large amounts of maintenance budgets are associated with river management. For decision makers it is important to know expected costs or losses and the spread...master thesis 2017

de Jongh, L. (author)The coastal protection system of the Dutch low-lying hinterland is under increasing pressure due to growing population and high economic value combined with climate change and a rising sea level. Supplying sand to dunes, beach and shoreface by means of nourishments is a widely applied technique to increase coastal safety. Climate change and a...master thesis 2017

Dekker, M. (author), Leijnse, T. (author), Simonse, J. (author), Van Westen, B. (author)This main objective of this report is to find the cause of the erosion problem and to design a solution for the problematic situation in front of the Iberostar Varadero Hotel, Cuba. This hotel is situated in the eastern part of the Peninsula of Hicacos. For almost 40 years erosion problems are present at this location and need direct attention....student report 2017

de Schipper, M.A. (author), Darnall, John (author), de Vries, S. (author), Reniers, A.J.H.M. (author)Five years of beach topography data were examined to map the spatio-temporal patterns in beach scarp existence. Data of the Sand Engine were used, a mega scale nourishment implemented in 2011 at the Dutch coast. Topographic data were automatically and manually analyzed to recognize scarps in the dataset. Moments of destruction and persistence of...conference paper 2017

Luijendijk, A.P. (author), Velhorst, R.L.C. (author), Hoonhout, B.M. (author), de Vries, S. (author), Ranasinghe, Roshanka (author)This study presents some recent developments in coastal morphological modeling focusing on flexible meshes, flexible coupling between models operating at different time scales, and a recently developed morphodynamic model for the intertidal and dry beach. This integrated modeling approach is applied to the Sand Engine mega nourishment in The...conference paper 2017

(author)The presence of complex nearshore sand bar patterns (i.e. alongshore bathymetric variability) has an impact on local currents, affecting recreational safety and nearshore mixing processes. This study assesses the evolution of alongshore bathymetric variability along the Delfland coast in The Netherlands, over the first 5 years after construction...conference paper 2017

Hoonhout, B.M. (author), de Vries, S. (author)Spatial variations in aeolian sediment transport were measured at the Sand Motor mega nourishment in The Netherlands during a six week field campaign in the fall of 2014. A consistent significant increase in sediment transport in downwind direction (positive gradient) was measured over the intertidal beach area, indicating that the intertidal...journal article 2017

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

Bruins, R.J. (author)To counteract relative sea level rise, Rijkswaterstaat nourishes the Dutch coast with sand. This sand spreads out over the shoreface zone, beach and dunes. One of the nourishment types is the shoreface nourishment. In this thesis, data of historical shoreface nourishments along the Dutch coast is analysed to find the factors that influence this...master thesis 2016

(author)Bed sediment composition, with a focus on the median grain size D<sub>50</sub>, was investigated at a large-scale nourishment (The ‘Sand Motor’) at the Dutch coast (∼21.5 million m<sup>3</sup> sand). Considerable alongshore heterogeneity of the bed composition (D<sub>50</sub>) was observed as the Sand Motor evolved over time with (1)...journal article 2016

Gijsman, R. (author)Relative sea level rise and climate change, but also the migration of the growing world population to the coast, continuously increase the pressure on the coastal system. In combination with the increased awareness for sustainability, the interests in the coastal zone become integrated and complex. Integrated Coastal ZoneManagement (ICZM)...master thesis 2016

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
