Preliminary Results of Modelling Simulation for High-resolution Hydrodynamic Fields for Central Vietnam's Water
Main Article Content
Abstract
This paper presents the development of hydrodynamic simulation models (waves, currents) for the Vietnam East Sea and nestingto coastal area (applied in the coastal area of Phu Yen province). The COAWST modeling system has been used. This is an open source system which supports optimal parallel calculation and allows solving large-scale simulation problems. The model has been calibrated and verified by deep water wave data at the stations of Bach Long Vi, Con Co, Phu Quy and Phu Quoc for good results. Along with that, with the goal of having high resolution for the central Vietnam water, the model has been set up with coastal wave data in Phu Yen for very good results, the correlation coefficient between calculation and measurement is up to 0.95. The results of the current field, surface temperature from the model of the ocean shows the similarity with the verification data, especially simulating the typical rising water phenomenon in Ninh Thuan - Binh Thuan area. However, some stages have complicated movements, the model has not been closely simulated, for example in the area of Phu Quy island.
