Dynamic reconfiguration of aquatic plants and its interrelations with upstream turbulence and drag forces

摘要: This article explores the interrelations between flow, fluctuating drag forces, and dynamic reconfiguration experienced by four freshwater plant species in response to turbulent open-channel flow. The study is based on experiments conducted a laboratory flume using single specimens of Ranunculus penicillatus, Fontinalis antipyretica, Myriophyllum alterniflorum, Callitriche stagnalis. A significant correlation fluctuations, movements, upstream turbulence was found. data also revealed that plants general exhibited spatial flapping-like motion, with propagation velocity perturbations along being approximately constant comparable flow velocity. analysis statistical moments, spectra, cross-correlations, coherence functions provided strong support conclusion directly affects force exerted plants, addition effect turbulence.
