The experiments of physical modeling of this research have been done in the flume of the Soil Conservation and Watershed Management Research Institute (SCWMRI). The waves applied to the structure model are irregular and the energy spectrum of the applied waves is JONSWAP. To study the slope effect of seawalls, the structure slopes of 1:2.5, 1:2 and 1:1.25 have been tested. The material of armor layer have been regarded with the scale of 1:20 model and grading class of D85/D15=1.82. A number of 1000 waves were applied on the structure over the research in general and some 57 experiments have been totally accomplished. The achieved outcomes of the experiments after drawing the figures were analyzed and the effect of the structure's primary slope on the amount of waves overtopping were investigated. The outcomes indicate that the primary slope enjoys no considerable effect on the amount of overtopping from the reshaping rubble-mound seawalls, although following the fall of the structure's primary slope, the mean overtopping discharge faces with a least decrease.

Hydrodynamical and geometrical parameters were analysised. In this research optimum height of skirt to water depth ratio is determined.

This technique has been adopted in construction of many types of engineering structures such as retaining walls, bridge abutments, foundations, dams and embankments. In recent years, application of reinforced earth have been developed in marine environment for coastal protection, wharf and harbour structures. In comparison with conventinal concrete retaining walls, there are many advantages for reinforced earth walls such as: less cost, ease and high speed of construction and no need for proffessional labor. These advantages, make the reinforced earth wall a perfect substitution for other conventional structures to be used in coastal environment. This invetigation evaluates the behaviour of reinforced earth wall when used as a coastal protection structure or as a wharf or harbour structure. For this purpose, the effects of marine environmental factors such as saturation, submergenc...
