Wengrove, Meagan E. (author), de Schipper, M.A. (author), Lippmann, Thomas C. (author), Foster, Diane L. (author)Field observations of small scale seabed morphology were obtained over 4 weeks at two locations separated 66 m along a cross-shore transect during the 2014 MEGAPEX Experiment conducted as part of the longer term Sand Engine mega-nourishment project along the North Sea Coast of The Netherlands. The seafloor was continuously covered by dynamic...journal article 2022

Wengrove, M. E. (author), Foster, D. L. (author), Lippmann, T. C. (author), de Schipper, M.A. (author), Calantoni, J. (author)Bedload transport is an important mechanism for sediment flux in the nearshore. Yet few studies examine the relationship between bedform evolution and net sediment transport. Our work contributes concurrent observations of bedform mobility and bedload transport in response to wave dominant, current dominant, and combined wave-current flows in...journal article 2019

Huisman, B.J.A. (author), Ruessink, B. G. (author), de Schipper, M.A. (author), Luijendijk, Arjen (author), Stive, M.J.F. (author)Large perturbations in the coastline, such as the 'Sand Motor' nourishment (∼21 million m<sup>3</sup>) at the Holland coast, can initiate considerable spatial and temporal changes in the median grain size (D<sub>50</sub>) of the sea bed on the lower shoreface. The relevance of hydrodynamic conditions for the development of the heterogeneity...journal article 2018

Wengrove, M. E. (author), Foster, D. L. (author), Lippmann, T. C. (author), de Schipper, M.A. (author), Calantoni, J. (author)Although combined wave-current flows in the nearshore coastal zone are common, there are few observations of bedform response and inherent geometric scaling in combined flows. Our effort presents observations of bedform dynamics that were strongly influenced by waves, currents, and combined wave-current flow at two sampling locations...journal article 2018

Huisman, B.J.A. (author), de Schipper, M.A. (author), Ruessink, B. G. (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
