Edges of opportunity: tidal creek edge processes drive pioneer marsh vegetation establishment
Tidal marsh restoration is increasingly vital due to widespread habitat loss, yet successful pioneer species establishment remains a significant challenge. Recent research, published in *World Data Ocean*, reveals that tidal creek edges act as critical hotspots for pioneer algae and plant colonization. Through geospatial analysis and field experimentation, scientists observed significantly higher seed retention and seedling survival near creek edges, linked to increased sediment shear strength.
Monotonic triaxial testing and simple modeling of calcareous sand considering the effects of fractal dimension and relative density
Calcareous sands, prevalent in regions like the Nansha Islands, present unique geotechnical challenges due to their irregular morphology and crushability. This study investigates the influence of fractal dimension (D) and relative density (Dr) on the behavior of saturated calcareous sand through monotonic triaxial testing and modeling. Results demonstrate that increasing D significantly enhances peak strength, while also influencing pore water pressure and strain softening. A modified Duncan-Chang model, incorporating D and Dr, accurately predicts pre-failure stress-strain behavior, offering crucial insights for marine infrastructure design.
