Wave runup on vertical structures

[RTIDamEngineer]

I am working on a reservoir freeboard analysis. I am having difficulty finding information on the interation between waves and vertical structures. I have come across a lot of info on runup for slopes, but none on vertical walls. My inclination is to say that there wouldn't be any runup, but I would like to verify that. I have looked in the USACE Coastal Enginnering Manual. Does anyone have a source for information on this subject? Does anyone know where I could get a copy of the old Shore Protection Manual and ETL 1110-2-221 "Wave runup and wind setup on reservoir embankments" by the USACE?

Thanks for the reply. Unfortunatly I have already looked through all the USACE Resources I know of. If you check the corp publications pages you will see that the Shore Protection Manual(SPM) and the ETL I mentioned in my original post are not available. I know that the new CEM has replaced the SPM, but I still think it would be a valuable resource.

The ETL that you are looking for doesn't appear to be on the Corps website.

Our recent research (for a floodwall on top of a dam) indicates that the USBR appears to have abandoned the use of parapet walls since about 1945. The Corps of Engineers suggests walls no higher than 3 ½ feet. From visual observation of sea walls, I would expect that there is some runup and significant dynamic loads from waves which strike the wall.

Thanks CVG. This isn't a new design, but an evaluation of an existing structure for freeboard adequecy. It has turned out to be quite a envolved and intresting problem.

You could also try to contact your COE division or district office. Many engineers in the Corps keep old manuals. I did when I worked there.

good luck

I found this publication that may be of interest:

http://cirp.wes.army.mil/cirp/cetns/chetn-iii68.pdf

"Estimating Irregular Wave Runup
on Smooth, Impermeable Slopes"

(I have copies of the SPM, 1977 3rd addn. if you need something specific)
