Data underlying the publication: "Nature-based shoreline protection in newly formed tidal marshes is controlled by tidal inundation and sedimentation rate"

Our aim was to improve the current understanding of the influence of tidal inundation and sedimentation rate on the development of tidal marsh sediment strength and erosion resistance in restored and newly created tidal marshes, as well as the influences of drainage, sediment, and vegetation on this development. For this, we measured sediment strength and erosion resistance of sediment layers with different accretion ages in a closely monitored restored tidal marsh with a controlled reduced tidal exchange along the Scheldt estuary in Belgium. When this tidal marsh was created in 2006, initial bed elevation differences in the area led to differences in tidal inundation frequency and duration, and differences in sedimentation rate. By also determining drainage characteristics and measuring sediment and vegetation characteristics, we were able to identify the effect of these variables on the development of sediment strength and erosion resistance.This dataset contains all data on sediment strength, erosion resistance, tidal inundation characteristics, sedimentation rates, and drainage, sediment, and vegetation characteristics that we measured at the measurement locations.

本研究旨在深化对潮汐淹没与沉积速率如何调控修复型及新建潮汐沼泽沉积物强度与抗侵蚀能力发育过程的认知，同时明晰排水条件、沉积物属性与植被特征对该过程的影响。为此，我们选取比利时斯海尔德河河口一处经严格监测、采用控制性减潮汐交换方案的修复型潮汐沼泽，针对不同沉积年龄的沉积物层，测定其沉积物强度与抗侵蚀能力。该沼泽于2006年建成之初，区域内初始床面高程差异引发了潮汐淹没频率、淹没时长及沉积速率的空间差异。此外，我们还测定了研究区域的排水特征、沉积物与植被属性，由此明确了上述变量对沉积物强度与抗侵蚀能力发育过程的调控作用。本数据集涵盖了所有在实测点位采集得到的沉积物强度、抗侵蚀能力、潮汐淹没特征、沉积速率，以及排水条件、沉积物与植被属性相关数据。
