Flow modification associated with mangrove trees in a macro-tidal flat, southern China

Yang Chang  Yining Chen  Yan Li  
【摘要】:Limited studies have investigated the modification of tidal currents by mangrove trees. In particular, the impacts of mangrove trees on a vertical velocity profile remain unclear. An automatic system is developed to observe the vertical velocity profiles within a mangrove forest composed of artificially introduced Kandelia obovata located on the Ximen Island, the southern Zhejiang Province. The results reveal low flow velocities throughout the vertical profile within the mangrove forest. The vertical profile shows an overall decrease of the velocity with an increasing height above the bed. This pattern is due to the vertical increase of the drag force by the trunks and tree canopies.In addition, the turbulent energy density also varies vertically, corresponding to the vertical structure of the mangrove trees. In comparison with the vertical structure of flows within bare mudflats(semi-logarithmic) and salt marshes(nearly J-shape), the mangrove trees are shown to have a considerable impact on the vertical velocity profile in different ways.
