Figure 9. Dolos intermediate structural design 



response in the physical model justify the benefits. If a moderately 

 sophisticated hydrodynamic stability physical model study is done and if the 

 appropriate dolos structural instrumentation for the model-sized units is 

 available, measuring structural response in the physical model adds little to 

 the hydraulic testing costs. As parametric data become incorporated into the 

 design procedure, the need for structural measurements in the physical model 

 should decrease . 



82. Because most of the above CAU design methods involve costly or 

 unverified techniques, the instrumentation of small-scale model armor units is 

 becoming an increasingly viable option, particularly with advances in 

 small-scale instrumentation technology (Markle 1990a) . Use of the load cell
