| Summary: | Wave resonance phenomena in a basin can cause enormous damage to the
environment. The natural resonant period of the basin is one of the primary causes
of the resonance phenomenon. The resonance phenomenon is caused by external
forces coming into the basin with a similar period as the natural period of the
basin. One way to mitigate this resonance phenomenon is to construct a breakwater.
We will observe the analytical natural period of basins with one block
of rectangular submerged breakwater with rough and smooth surface, also basins
with two blocks of smooth rectangular submerged breakwater. The analytical
natural period is obtained using the linear shallow water equation (LSWE). We
will conduct numerous numerical simulations to confirm and detect the existence
of the resonance phenomenon. For basins with rough bottom surface, we will also
calculate the optimal friction coefficient required to prevent the resonance occurrences. |
