TAILIEUCHUNG - Modelling study of the nearshore wave climate in Quy Nhon

This paper presents the model results of a wave modelling study using SWAN spectral wave model. The main objectives of the study are to determine nearshore wave climate along the coast of Quy Nhon city. The nearshore wave climate can be then used to provide inputs for the design of the access channel and to assess the siltation rate in the nearshore coastline. | RESEARCH RESULTS AND APPLICATIONS MODELLING STUDY OF THE NEARSHORE WAVE CLIMATE IN QUY NHON Nguyen Thanh Hoan1 Abstract This paper presents the model results of a wave modelling study using SWAN spectral wave model. The main objectives of the study are to determine nearshore wave climate along the coast of Quy Nhon city. The nearshore wave climate can be then used to provide inputs for the design of the access channel and to assess the siltation rate in the nearshore coastline. A wave model for Quy Nhon has been setup to transform offshore waves to inshore locations. This has been undertaken to derive the normal wave conditions in the existing situation. The SWAN spectral modelling software has been used to transform offshore wave information obtained from NOAA to inshore locations. For the normal conditions the combined sea and swell wave climate has been considered. The model was validated against measured wave data for a period of most severe monsoon waves . December 2013. An advanced technique has been used to make it possible to transfer 34 year waves conditions from offshore to nearshore.

Introduction Nhon Hoi Economic Zone is located in Binh Dinh Province in Central Vietnam 1 . It is located on a peninsula named Phuong Mai to the North of the provincial capital Quy Nhon. Access to the new Industrial Zone is by road from the North or across the Thi Nai Bridge crossing over the lagoon from the West. Fig. 1 presents the master plan of Nhon Hoi Economic Zone. The industrial zone has a small waterfront along the lagoon on the south west side. A rocky hillside of approximately 50 meters above sea level is present on the east side of the economic zone. An oil 27bn refinery complex is planned to be built in this Economic Zone. The main investor is Thailand s PTT 2 . Import and export are .
