35. The Crescent City Dolos Structural Design Procedure is divided 

 into three phases: (a) Preliminary Design, (b) Intermediate Design, and 



(c) Final Design. These modules, or design phases, are subsets of the break- 

 water modular design procedure. The first phase, the preliminary or recon- 

 naissance design phase, is a desktop study that utilizes the program CAUDAID 

 to determine a dolos design configuration. The second phase utilizes the 

 physical model, if necessary, to verify both the design stress level and the 

 hydrodynamic stability of the design dolos. The final phase includes evalu- 

 ation of the design stress and, if necessary, evaluation of special 

 strengthening schemes.
