Typhoon wave modelling application for planning the harbor in Danang city, Viet Nam

Analysis of wave propagation in shallow water is considered as one of the important keys in assessing the shoreline evolution, as well as an important basis for assessing the impact of waves on coastal structures. With the purpose of simulating the wave propagation process in the area of Danang Bay, as a basis for assessing the impact of waves and wind on the shoreline evolution as well as giving appropriate construction measures, the study has analysed wave propagation in an area of about 60.3 × 103 km2. Using the MIKE 21/3 module of the Danish Hydraulics Institute, and simulating under the most extreme wave conditions, under the impact of hurricanes level 10, level 13 and level 16 (conditions and storm trajectories based on Nari storm in 2013) as well as the influence of the flow of the Cu De and Han rivers, the study initially showed changes in velocity fields over time, changes in water level and waves in Danang Bay. These results are expected to become the basis for consultation with local authorities in coastal management and disaster prevention, especially in the context of increasingly complex climate change and sea level rise.
