Overview of research on Hydrodynamic and rip current studies:
In the 2-dimensional flow calculation model of Nguyen Thi Bay, the factors affecting coastal flows have been fully considered. However, in this calculation model, the author has not considered calculating wave characteristics such as wave height, period, wave direction as well as wave stresses that have not been calculated in the model but must go through the results. Calculate waves from other models such as RCPWave, REFDIFF, MIKE 21 NSW,… or include them in the program as constants.
In the problem of calculating the Rip current, the impact of ocean waves is one of the important factors constituting the Rip current. Therefore, the thesis will continue to develop Nguyen Thi Bay’s two-dimensional flow calculation model. In particular, consideration is given to the change in ocean wave factors as well as connecting the wave propagation calculation module to the coastal current model, in order to complete the mathematical model to calculate the Rip current.
