| Description | Influence of hydraulic conditions on the bed-level fluctuation of mangrove forest during flood was clarified at the Okukubi River in Okinawa Island, Japan. Bed-level changes were monitored every one month from June 2012 to July 2015 at 18 stations. While non-dimensional shear stress during a flood was estimated by two-dimensional bed deformation analysis. Then relationship between observed bed-level change and non-dimensional shear stress was evaluated from correlation analysis. Bed-level change negatively correlates with non-dimensional shear stress during large flood. While during small flood, bed-level change doesn't correlates with non-dimensional shear stress. These results represent that bed-level fluctuation is occurred at sites where large non-dimensional shear stress is keeping during large floods. This condition can apply to selecting priority site in order to restoration of degraded mangrove forest.
