Toelichting (Engels) This study explored the factors influencing embryo dune growth and the impact potential on foredune development and coastal defence from 2016 till 2018. Man-made embryo dunes on a research field in Terschelling were monitored over three years using an unmanned aerial vehicle equipped with Red Green Blue and Near-Infrared cameras. With a constructed Digital Terrain Model, Digital Surface Model, Enhanced Normalized Difference Vegetation Index orthomosaics and annual coastal measurements, the slope of the beach plain, mean water level, roughness, aspect, vegetation height and the distance to the sea were calculated and used to estimate explanatory factors of embryo dune volume and height development. From wave height, sea level, beach nourishments, wind direction and wind speed data time series were constructed and compared to embryo dune development. The difference between foredune development on coastal sections with and without the presence of embryo dunes were investigated. With knowledge of foredune volume and embryo dunes the impact on coastal defence was determined. The accuracy of the used calculations and the height and location aspects of the used data were evaluated.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
