Fig. 4.
The chart presents flow velocity and Froude number for different barrier locations along the flume. At F B 1, velocity ranges from about 7 to 10 meter per second and Froude number from about 5.5 to 7. At F B 2, velocity ranges from about 6 to 7 meter per second and Froude number from about 5.8 to 6.3. At F B 3, velocity ranges from about 3.5 to 5 meter per second and Froude number from about 4.5 to 6. At F B 4, velocity ranges from about 3.5 to 5.8 meter per second and Froude number from about 4 to 5.5.Flow velocity (v) and Froude number (Fr) along the flume at respective barrier locations. Mean values are represented by the horizontal lines within the box plots. Whiskers represent the extent of minimum and maximum values at each barrier location
