Tidal Simulation around Japanese Coastal Region with a Global Ocean Tide Model

Study on Future Storm Surge Around Suo-Nada Sea

“…For the simulation on storm surge, not only storm but also tide was given as one of the external forces hence the domain needs to be validated for both tide and storm surge. For examining it, past study performed by Yoshiaki and Hidenori (2010) was referred. In the study, the sensitivity of tidal simulation to the several model size (See Figure 3.1.1) was investigated.…”

“…In the study, the sensitivity of tidal simulation to the several model size (See Figure 3.1.1) was investigated. (Yoshiaki and Hidenori, 2010) In the study, a Global Ocean Tide Model (NAO. 99jb model) was used for the tidal simulation.…”

“…This is because that the open boundary at which the tidal values were given was located far in Case3 comparing other cases thus this domain size seems not to be suitable for the storm surge simulation with tide. (Yoshiaki and Hidenori, 2010) 2) Examination of computational domain for FVCOM Based on the past study (Yoshiaki and Hidenori, 2010), two kinds of computational domains were created for a numerical simulation (See 3.1.3 Computational domains which were created based on the past study (Yoshiaki and Hidenori, 2010) With those domains, tidal simulations were performed by giving estimated astronomical tide from NAO.99jb (Tsumoto, et al, 2000) to an open boundary condition and Seeing the results, simulated value in Case1 could mostly reproduce predicted value though there are still some errors when it becomes the minimum, approximately 0.3m. On the other hands, simulated value in Case2 slightly had a phase shifted compared to the predicted one besides some errors can be seen similarly in Case1.…”
