The Sri Lankan Port City project provides land for urban construction through land reclamation,a large number of dredgers,traffic vessels,and cargo ships are employed during the construction process.Therefore,it is necessary to simulate the wave field during the construction process to evaluate the influence of waves on engineering ships.Based on GFS sea surface wind field data and GEBCO water depth data,the wave numerical models WaveWatch Ⅲ and SWAN were nested in multiple layers to establish a numerical simulation system suitable for wave field in the Port City area of Sri Lanka.The system was verified by comparing with the measured data.Based on this system,numerical analysis was conducted on the wave field in the Port City construction area at different construction stages.The trend of wave height,period and direction in the whole construction process of typical construction site was obtained.This paper provides an effective method for the numerical simulation of wave fields in nearshore waters,and provides an important reference basis for the reasonable arrangement of engineering ship operation window and the improvement of construction efficiency.
