CELLULAR BLOCKS 



Precast cellular revetment blocks being 

 placed by hand, Buffalo Creek, N.Y. 



Prototype Installation : 

 Buffalo Creek, New York. 



1 on 2 slope revetment used on a river bend to stabilize bank 

 (Parsons and Apmann, 1965). 



Wave Tank Tests: 



Unknown . • 



Design Factors : 



Zero-damage wave height: 4 to 5 feet (estimated). 



Wave runup: 0.7 to 0.9 compared to smooth slope (estimated.) . 



Wave reflection: Moderate (estimated). 



Remarks : 



Cellular blocks weigh 83 pounds each. 



Block size is 24 by 16 by 4 inches high with 24 2- inch-square cells 

 per block. 



Cells reduce block weight, trap littoral drift, provide uplift 

 pressure relief, and reduce runup.
