Artificial Reefs

Definition:
"An artificial reef is a human-made underwater structure, typically built to promote marine life in areas with a generally featureless bottom, control erosion, block ship passage, or improve surfing." - Wikipedia

Artificial Reefs can help us create surfing hot spots where there are already over crowded beachs. They can promote a towns tourism and improve the way of life for everybody. The first attempt at one of these Reefs was in El Segundo near Los Angeles.
 The first Reef was constructed out of large granite blcoks formed into a pyramid. Another was made out of large sand bags (with each one nearly the size of a bus) counting 400 in total that formed a large reef that acted to both improve waves and also stabilize beach nourishment.
 Although a Artificial Reef can create a small town into a "Booming" centre for surfing it face very tough laws and regulations before they are created and will spend years weaving through all the departments and regulations to finally get to building them.
 Opposite to the popular belief that Artificial Reefs that create large waves actually help the beach and swimmers. By having a large Reef off the coast the waves break earlier that disperses the waves energy meaning that it is safer for swimmers to swim and also causes less erosion.
 There is huge cost to a Artificial Reef though and they can take up to a year to complete and if not planned well can take years to create when using sand bags, that is one of the reasons that if you are trying to make a artificial reef to promote marine life they will use boats usually military boats or carriers like the USS Spiegel Grove.
