However, not all physical processes are currently fully understood, complicating accurate reproductions in models and the risk assessment of areas protected by dunes. This dissertation aims to study two such physical processes that are relevant to dune erosion during storm surges in the swash-dune collision regime. The first process is the suspension of sediments in the inner surf zone. The second process studied is sediment transport due to soil instabilities, i.e. the slumping (or avalanching) of sediments from the dune face. To study both processes, a prototype scale field experiment was conducted in the winter of 2021-2022.","AbstractOtherLang":"Duingebieden fungeren vaak als de belangrijkste waterkering voor laaggelegen achterland tegen stormvloeden met duinafslag in het botsingsregime. Echter, niet alle optredende fysische processen tijdens duinafslag zijn momenteel volledig doorgrond, wat nauwkeurige reproducties in modellen en de risicobeoordeling van gebieden beschermd door duinen compliceert. Dit proefschrift heeft als doel om twee dergelijke relevante fysische processen te bestuderen. Het eerste proces is het opwoelen van sediment in de binnenste brandingszone. Het tweede bestudeerde proces is sedimenttransport als gevolg van bodeminstabiliteiten, oftewel het afschuiven van sediment van de duinhelling (slumpen). Om beide processen te onderzoeken is er in de winter van 2021-2022 een grootschalig veldexperiment uitgevoerd.","BibLvlCode":"M","StandardTitle":"
