Sources - Plausibility?
removed " through satellite photographs". sources? plausibility? beyond even the military. reality - breakwaters are monitored by guys in boats
I've been to Crescent City, CA, where they have a dolos displayed with an explanatory plaque saying the numbers on the tetrapods / doloses are intended to monitor movement through SATELLITES (i also walked on the breakwater and can affirm that some of the doloses / tetrapods are in fact numbered).
If you have any information that this is incorrect please present it. I think it should be obvious that small movements in breakwater elements cannot be observed "from a boat". I could be wrong of course...so make your case.

This reads like a commercial. Some argue that tetrapods accelerate beach erosion by disrupting the natural processes that shape the coastal environment. —Preceding unsigned comment added by 188.8.131.52 (talk) 11:21, 13 May 2011 (UTC)
- Indeed there are many who do take that line. The arguments pro and con have aroused more general interest since the Hurricane Sandy flooding. In countries where land is at a premium though, for example the Netherlands and Belgium, allowing nature to take its course is not an option. This, however, is a consideration not limited to tetrapods and belongs more properly to an article on coastal erosion and defences. Everybody got to be somewhere! (talk) 00:00, 21 May 2013 (UTC)
