WebMay 17, 2024 · Drag coefficient has been commonly used as a quantifying parameter to represent the vegetative drag, i.e., resistance to the flow by vegetation. In this study, the measured data on the drag coefficient for rigid vegetation in subcritical open-channel flow reported in previous studies are collected and preprocessed for multi-parameter analysis. … WebDrag coefficient derivation considering stem Reynolds number, Froude number and stem staggering pattern. (Hasimoto, et al., 2009) Plant Arrays. Nepf (1999) extended the research and modelling of the drag induced by individual cylinders by defining the effect of a stem population density on the drag coefficient. Physical modelling was used to ...
