Data underlying the publication: "Nature-based mitigation of shoreline erosion risks in tidal marshes created by managed realignment vs. sediment nourishment"

We aimed to improve our current understanding of the development of sediment strength and erosion resistance under a high flow velocity in restored and created tidal marshes, and of how this development is affected by tidal inundation, sediment characteristics, and vegetation. We compared sediment strength and erosion resistance at a managed realignment site (since 2015) and at a sediment nourishment site combined with brushwood groynes (since 2018). At both these sites, we selected locations with differences in tidal inundation duration, sediment grain size, and vegetation presence or absence, to test the effect of these factors on sediment strength and erosion resistance. This dataset contains all data of these two sites.
