The U values reached their minimum at the scour hole bed and elevated using the distance in the scour hole bed.Figure five. Streamlines about the abutment (a,b) for the un-vegetated bed and (c,d) for the vegetated Figure 5. Streamlines around the abutment (a,b) for the un-vegetated bed and (c,d) for the vegetated bed at two heights of dd= 0.six cm and dd =10.0 cm in the stabilized scour bed. Note that the selection of bed at two heights of = 0.6 cm and = 10.0 cm from the stabilized scour bed. Note that the range of the colour scale is just not equalized for greater illustration. the color scale is not equalized for better illustration.A cylindrical polar coordinate (Figures 61) was used to represent the flow patterns. A cylindrical polar coordinate (Figures 61) was used to represent the flow patterns. The time-averaged velocity elements in (, z) are respectively represented by (u, v, v, The time-averaged velocity elements in (, r, r, z) are respectively represented by (u,w), w), whose corresponding fluctuations are (u’, v’, w’). For this experimental u describes whose corresponding fluctuations are (u’, v’, w’). For this experimental study,study, u describes the tangential velocity, v is made use of to denote thevelocity, and theand the vertical vethe tangential velocity, v is employed to denote the radial radial velocity, vertical velocity is locity is expressed as w.

The tangential velocity u, amongst all 3D velocity components, played a vital part in building the scour hole plus the turbulence JMS-053 Data Sheet structure. The magnitude of u without the need of vegetation increased with hole along with the turbulence structure. The magnitude of u with no vegetation enhanced with the azimuthal degree from 0to 120and then decreased at = 160(in the downstream the azimuthal degree from 0 to 120 and after that decreased at = 160 (in the downstream zone of the abutment). The magnitude of u was far more important when the scour depth zone with the abutment).
