| Zusammenfassung |
| The southern coastal area of Korea has often been damaged by storm surges
and waves due to the repeated approach of strong typhoons every year. The
integrated model system is applied to simulate typhoon-induced winds, storm
surges, and surface waves in this region during Typhoon Sanba in 2012. The
TC96 planetary boundary layer wind model is used for atmospheric
forcing and is modified to incorporate the effect of the land's roughness on
the typhoon wind. Numerical experiments are carried out to investigate the
effects of land-dissipated wind on storm surges and waves using the three-dimensional,
unstructured grid, Finite Volume Coastal Ocean Model (FVCOM),
which includes integrated storm surge and wave models with highly refined
grid resolutions along the coastal region of complex geometry and
topography. Compared to the measured data, the numerical models have
successfully simulated storm winds, surges, and waves. Better agreement
between the simulated and measured storm winds has been found when
considering the effect of wind dissipation by land roughness. In addition,
this modified wind force leads to clearly improved results in storm surge
simulations, whereas the wave results have shown only slight improvement.
The study results indicate that the effect of land dissipation on wind force
plays a significant role in the improvement of water level modeling inside
coastal areas. |
