Mangrove Vegetation as a Protective Solution for Coastal Protections

Authors: Sarah Palmer, Mathew Withmarsh

Mangroves play a prominent role in obstructing water currents in riverbanks, shorelines, and coastal areas. Mangrove roots have the significant contribution to the resiliency of the vegetation structure. In this work, the flow characteristics past a cluster of circular cylinders (patch), which represents the mangrove roots, are investigated. We found that blockage parameter for a patch decreases with porosity for all Reynolds numbers. A von Kármán vortex sheet is predicted behind the patch with a periodicity which agrees well with experiment. In addition, the vorticity field for the least porous patch reveals a delay in the formation of von Kármán vortex street due to the small vortices in the near wake, whereas the vortices evolve in the far wake and produce swirling flow
