| Abstract: |
| The paper presents expressions of eigen vales for oscillations within a rectangular harbor,and then uses the Boussinesq model to simulate harbor oscillation in rectangular basins and their extensional shapes to investigate the effects of boundary conditions.The entropy measuring equipartition is introduced to quantitatively compare oscillations within different basins.It is shown that slight changes of the short side of rectangular basins could result in that energy re-distribute in more modes,which may mitigate oscillations dramatically. |
