Drag Comparison for Coastal Species for Shoreline Protection
Drag coefficient commonly used to indicate the frictional resistance produce by the object in the fluent environment. This parameter has commonly used to examine the attenuation of wave towards the sea shore. However, lack of understanding on drag coefficients tree morphology density and arrangement and the minimum shoreline belt width. This study compares two coastal species and evaluates the potential or their stilt root system to dissipate the velocity. This study analyses the drag value on the cross sections of the stilt root model. The slice with maximum result of drag value will be used for the specimen preparation in velocity dissipation analysis. Both analyses were carried out using Computational Fluid Dynamics (CFD) by ANSYS Fluent program. The velocity magnitudes on the analysis path were extracted to evaluate the behaviour of the flow dissipation. Root zone of the stilt root model contributes higher dissipation on the velocity than the single stem. The highest drag value is observed at 0.5 m height of the stilt root model from ground. Higher density of forest stands contribute to higher dissipation of velocity. The study found that 135–203 m is the minimum shoreline belt width in where the result varies to diameter. This study could be applied for properly design the wave breaker for artificial protector for mangrove seedlings.
