Figure 7.
The graph plots time against maximum scour depth S max in metres. The C F D curve increases rapidly from 0 to about 0.05 metre by 800 seconds, then rises more gradually to about 0.06 metre and remains nearly stable until 4500 seconds. Experiment markers appear near 0.032 metre at 300 seconds, 0.042 metre at 1050 seconds, and 0.069 metre at 4500 seconds.Time evolution of the maximum local scour depth predicted (line) and compared with experimental values at , 1050 and 4500 s
