- 7. Considerations ClimateChange7 In the presenceof thick sand deposits, a rubble foundation with adequate scour protection is recommended lest strong tidal streams, water currents or wave turbulence scour away the sand underneath the foundation. The core of a solid breakwater should be cast in concrete; not more than 50 percent of this concrete may be replaced by pieces of rock.

- 12. To be effectiveas a breakwater … • the motions of a floating structure must be of small amplitude. • the structure must respond to a spectrum of incident wave conditions. ClimateChange12
- 13. The efficiency ofa floating breakwater depends primarily on the ratio of : the width of the pontoon to the wavelength of the oncoming waves ClimateChange13
- 14. FLOATING BREAKWATERS • notsuitable for creating protected areas should never be installed. • on lake shores, where the waves tend to be very short (choppy) can installed. ClimateChange14
