Comprehending the bidirectional interactions between ecosystems and plant communities is essential for ensuring the conservation and sustainable development of Bruguiera hainesii. The study identified nine accompanying plant species within a range of 1.2-5.5 m, including five frequently encountered species and four commonly found ones. The research site is influenced by two distinct wind seasons: the Northeast monsoon (November to April) and the Southwest monsoon during the rainy season, with an average wind speed of 1.77 m/s. Correspondingly, the wave regime alternates with these seasons, featuring opposing directions. During the Northeast monsoon, wave heights average 2-2.5 m, while during the Southwest monsoon, they decrease to 1.5-1.7 m. The tidal regime in Con Dao is mixed semi-diurnal, with tidal ranges of 3-4 m at high tide and 1.5-2 m at low tide. Tidal currents primarily drive the flow regime, with dominant Northeast flow during early summer and seasonal shifts between winter and summer. Flow velocities range from 0.15 to 0.92 m/s, influenced by the Manning roughness coefficient. Sediment dynamics reveal that increased settling velocities correlate with higher suspended sediment concentrations, with total suspended sediment at point P1 approximately 70% greater than at point P2. These findings elucidate the seasonal and hourly dynamics of tidal waves and sediment transport, offering critical insights to support the effective conservation of B. hainesii.
