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.

本研究旨在深化对高流速条件下修复型与新建型潮汐沼泽（tidal marshes）中沉积物强度（sediment strength）与抗侵蚀性（erosion resistance）演化规律的认知，并阐明潮汐淹没、沉积物特征及植被对该演化过程的影响机制。本研究对比了两处试验场地的沉积物强度与抗侵蚀性：其一为2015年启用的管理型岸线调整场地（managed realignment），其二为2018年启用的配备梢料丁坝（brushwood groynes）的沉积物补给（sediment nourishment）场地。在两处场地中，研究人员选取了潮汐淹没时长、沉积物粒径及植被覆盖情况存在差异的点位，以此检验上述因素对沉积物强度与抗侵蚀性的影响。本数据集涵盖上述两处场地的全部实测数据。
