Evaluate the stability of the proposed 4-ton dolos trunk section 

 when exposed to design wave and still-water level (swl) condi- 

 tions specified by NCB. 



Determine the degree of breakwater damage that could occur on 

 the 4-ton dolos design for a storm condition (specified by NCB) 

 that exceeds the design wave conditions. 



Determine the maximum nonbreaking wave heights for which the 

 existing 2-ton dolos design and the proposed 4-ton dolos and 9- 

 to 20-ton armor-stone designs could be considered adequately 

 designed.
