In this paper, solitary wave run-down height and the geometric characteristics of solitary wave-induced strewing of armor units are investigated. In the experiments, natural sand and grain having different diameters are used. Run-down heights for not armored and armored beaches are evaluated and empirical formulas are suggested. From the results of these experiments, it was observed that armor units caused a decrease of approximately 35% run-down height. The relation between the run-up and run-down height is given by a formula. Subsequently, the area along the slope that had to be protected (such as a pipeline) was to be considered. In the experiments, this area was protected in two different ways (Alternative L Alternative II). The strewing of the armor units forming the protective layer was studied. It is concluded that Alternative II is more suitable than Alternative I for protected area. The most important variables strewing of armor units were defined by using experimental results. These variables are written as a dimensionless group named as par 3 by using pi theory. The empirical formulas between the geometric characteristics of strewing of armor units and dimensionless group are proposed through regression analysis.
