Wave-induced reconfiguration of and drag on marsh plants

Salt marshes are a common feature in coastal regions and have been noted for their ability to attenuate wave energy, providing an important first line of defense. Marsh plants usually consist multiple leaves distributed along central stem. This paper constructed model predicting force on marsh plant by modeling the reconfiguration both stem waves. The individual leaf models full were validated with experimental measurements drag motion using live dynamically-similar under range conditions. Although exhibited greater than stem, they contributed more 70% drag. Plant produced that had weaker quadratic dependence velocity. A simplified model, which combines scaling laws leaves, is proposed validated. Wave variety species different morphology rigidity estimated compared.
