Research
My PhD project revolves around developing and doing experiments with field flumes. Using novel flume designs, we aim to answer new questions that cannot be answered with lab flume experiments.
The main focus of my research is finding biogeomorphic thresholds in inter- and subtidal areas. For example the onset of cliff formation on the edge of salt marshes and seagrass meadows, and spatial patterns in erodability on tidal flats.
Knowing these thresholds is essential to be able to predict tipping points in the response of these ecosystems to changing boundary conditions, for example due to climate change.
