Beach erosion using artificial reefs is a very complex subject.
I am familar with the Barcelona area and it is quite high energy. 2 meter
require a VERY wide crest width to be effective at beach erosion control. I
they are proposing some sort of porous concrete structures?
If you would like information on how it can be done to actually mimic a
reef go to www.reefbeach.com which is a division of our non-profit
Note there are several studies on this site which will give you much more
detail about the required crest and width height for submerged breakwaters
to the technical questions you seek.
I would suggest that you contact one of the leading scientific minds on
submerged breakwaters to get the answers you need. His name is
Dr. Lee Harris and the Florida Insititute of Technology
(lharris at fit.edu).
