The application of the MIKE 21/3 FM Couple model to simulate waves and coastal water levels in Quang Binh province

Abstract

When natural disasters occur, especially types such as storms, tropical depressions, floods, inundations,... the damages they cause are often significant. This is particularly true when there is a combined impact of different disaster types, such as upstream floods converging with storm surges and high tides. Calculating and simulating wave regimes and coastal water levels to assess their effects on river flood drainage is crucial. This paper presents the application of the MIKE 21/3 FM Couple model to simulate waves and coastal water levels in Quang Binh province, specifically at the Nhat Le river mouth. In this study, reanalysis data from the European Centre for Medium - Range Weather Forecasts (ECMWF), water level data from the Dong Hoi hydrological station, and wave data from the Con Co marine meteorological station were used. The simulation results reflect changes in coastal water levels under the influence of meteorological factors, and the evaluation results also show that the model's simulation quality is relatively good.
