Vegetation resistance is generally evaluated using drag coefficient CD related to friction factor f; however, some authors examined a possibility of employing classic hydraulic roughness coefficients (i.e., Nikuradse’s or Strickler’s) to calculate vegetation resistance in case of high submergence (h/k > 5, in which h is flow height and k represents vegetation height). In order to compare conventional roughness at high submergence levels, an experimental methodology was developed, focused, in particular, on fully submerged and rigid vegetation, for different hydraulic conditions and varying non-dimensional vegetation density.

Abstract
Vegetation resistance is generally evaluated using drag coefficient CD related to friction factor f; however, some authors examined a possibility of employing classic hydraulic roughness coefficients (i.e., Nikuradse’s or Strickler’s) to calculate vegetation resistance in case of high submergence (h/k > 5, in which h is flow height and k represents vegetation height). In order to compare conventional roughness at high submergence levels, an experimental methodology was developed, focused, in particular, on fully submerged and rigid vegetation, for different hydraulic conditions and varying non-dimensional vegetation density.File | Dimensione | Formato | |
