• Upper-bound velocity:
Upper-bound
The range of velocities: 4.6 ft/sec to 12.2 ft/sec
Note: t is assumed to be equal to 1 sec, as given in Equation 8.2.
Solution for #5: Local scour depth (S) around seaward row of pilings can be found using
Equation 8.10 as follows:
S = 2.0a
where:
Solution for #6: To find the total
localized scour (S TOT ) around piles, use
