This PhD project focuses on effects of the built environment on dune development. In the Netherlands and many other places dunes provide protection against flooding. To sustainable offer protection dunes need an influx of sediment, especially in a situation with sea level rise. Simultaneously, the beach and dune are very attractive for humans to recreate and settle. Therefore holiday homes and beach pavilions are (desired to be) built on the beach and in the dunes. These buildings influence sediment transport and morphology and thereby shape dune development. Knowledge on this interaction is essential for future spatial planning decisions on the beach. Therefore, the ShoreScape projects aims to the develop knowledge, tools and design principles for dynamic occupation of the land-sea interface.

To develop these tools and design principles, more knowledge on the effect of buildings on dune development is needed. Therefore, this PhD aims to understand and model how hard structures affect Aeolian (windblown) sediment flows and dune development. A part of my research will be to use scale experiments on the beach to determine and validate the erosion/deposition patterns of various building lay-outs. Furthermore, I will use this information to include beach-dune-building interaction in (cellular automata) models and use them to model the long-term evolution of the coastal landscape.
