scour depths

[sklgleb]

Hi all,

I need to come up with design depths for scour of pilings (working in SW Florida) - is there a standard reference guide/map that has this outlined? If not, is there a typical procedure to obtain a conservative value that DEP will not dispute?

Thanks,

G.S.

FEMA provides guidance on scour depth and related references in:

Erosion, Scour, and Foundation Design

In my experience (private work and DOT) we have used the rule-of-thumb that scour is about the same as rise of water surface during flood times.
