Variability in inundation characteristics across the elevation gradient and its stress effects

The data includes the characteristics of tidal inundation on the surface of the salt marsh by monitoring and the response of Suaeda salsa to different inundation characteristics. We integrated high-temporal-resolution field monitoring (10-min intervals) in the Yellow River Delta (YRD) with controlled indoor experiments using the keystone species S. salsa. A Fortran-based algorithm was developed to extract discrete tidal event characteristics from monitoring data across an elevation range of 0.8 to 1.4 m (at 0.05 m increments). The indoor experiments simulated various inundation regimes—varying in depth, duration, and frequency—to quantify their impacts on seed emergence, seedling survival, and growth.
