Changes of salt dynamics and distribution in coastal marshes (2018–2022)

Abstract:
This project aims to determine and quantify key mechanisms underlying salt transport and distribution in coastal salt marshes. Combining field measurements, laboratory experiments and numerical simulations, the proposed research will tackle long-standing questions concerning accumulation of excessive salt in the marsh soil, which imposes significant stress on marsh plants. The study will examine how temporal and spatial salinity variations lead to large density gradients that may trigger unstable pore-water flow and solute transport. The outcomes will advance our understanding of fundamental links between the marsh hydrology and ecology, and improve our scientific basis for evaluating the marsh ecosystem under different stress conditions.
