predicted from prototype test values. However, for severe levels of damage 

 the differences between small scale and prototype were not as great. When 

 profile surveys of severely damaged riprap were compared, the small-scale and 

 the prototype profiles were found to have similar shapes. Wave period was also 

 found to have less influence on the zero-damage wave heights in the small-scale 

 tests than in the prototype tests. The results of these tests were compared 

 with studies conducted by Dai and Kamel (1959), Thomsen, Wohlt, and Harrison 

 (1972), and the Hydraulic Research Station (1975).
