The Updated Change Trend of Sea Wave on Vietnam East SeaThe annual mean SWH trend of the East Sea in Vietnam is studied and evaluated based on data observed from the oceanographic stations and altimetry data from AVISO’s satellite. Oceanographic observed data analysis results show that the annual mean sea wave height decreases about 12,79 mm/year. Altimetry data (2009 – 2019) indicates that the annua...

Numerical Simulation of the Impact Response of Super Typhoon Rammasun (2014) on Hydrodynamics and Suspended Sediment in the Gulf of TonkinIn the present study, an open-source coupled numerical model based on Delft3D source code was performed and applied to simulate the hydrodynamic changes due to the Super Typhoon Rammasun in the Gulf of Tonkin (GTK). The results indicated that the typhoon strongly affects the current, water level, wave fields, and suspended sediment transport in ...
