Sustainable Coast management
The above method uses old tyres that are not wanted to act as groynes
They turn Destructive waves into constructive waves
Increase Deposition and Decrease erosion
None pollutant
Cheap to build & a free resource
If they break off, they are swept up ashore onto the beach and then put back
They have ecological value ­ providing coal water fish habitats
It will bring the coastline to equilibrium within 100 years.…read more
