Bridge Scour - Angle of Attack
Bridge Scour - Angle of Attack
(OP)
What is the best way to define and evaluate the angle of attack as it pertains to Bridge Scour? I have searched online, but I'm hoping somebody here can clarify it for me a little more.
Thanks in advance.

FHWA HEC-18 doesn't provide alot of information on it. From what I know, the angle of attack can make a significant difference in the calculated pier scour.
I guess that this has to be estimated during a representative event of what you want to model on the site (e.g. a flood).

Found nothing else than : "Greater skew = greater scour"!
