报告摘要：Benthic fauna and flora have long been recognized as an important factor influencing local sediment stability, deposition and erosion rates. However, their role in long-term (annual-to-decadal scale) and large-scale coastal morphological change remains largely speculative. To derive a quantitative understanding of the importance of benthos in sediment transport and morphodynamics of coastal zones, we firstly applied a machine learning-aided species abundance model to derive a complete map of benthos (functional groups, abundance and biomass), based on abundance and biomass measurements in field. The derived data were used to parameterize the benthos effect on sediment stability, erosion/deposition rates, and hydrodynamics in a 3-dimensional hydro-eco-morphodynamic model, which was then applied to two tidal basins in the Wadden Sea. By comparison between the different scenarios and measurements, the relative contribution of each biological functional group and abiotic drivers (tides, storm surges) as well as their interactions are disentangled.
