Full Text	f AMENDED 1 * Object of the Invention The present invention relates to an armor unit to construct armor layers of mound breakwaters, coastal revetments and groins for shore protection in maritime and hydraulic structures. Specifically, the object of the invention is an armor unit to protect against large waves which has a basic cubic or parallelepiped shape characterized by one or more protrusions on its faces to prevent coupling between units and to increase interlocking with the underlayer of quarrystone. Background of the Invention The manufacture of artificial quarrystone for the construction of mound breakwaters and shore protection structures is a well-known problem. Until now, different solutions have been applied unsuccessfully, through the design of numerous armor units, generally made of concrete, to construct armor layers of mound breakwaters for protection against wind wave attack. It is worth highlighting that said concrete units for breakwater armor layers are not to be confused with those used for the construction of artificial reefs, since said armor units are designed to resist against large wave breaking and are characterized by specific features such as stability and strength while the artificial reefs are used to improve or protect marine habitats and almost any unit made of any material denser than water is considered suitable. Concrete armor units for mound breakwaters may be classified according to the design, the construction process and the resistant performance against the wave storms. There are three main methods to place armor units in the construction of an armor layer: (a) random placement, (b) placed in a single layer and (c) regular uniform placement. The armor units with random placement (a) are the conventional armor units for substituting quarrystone, which are placed in more than one single layer and basically resist by gravity. Both simple and complex armor units can be 1 [• AMENDED 1 found within the group of random placement units. Cubic and parallelepiped blocks are simple armor units, robust, solid, easy to construct and flexible in their performance against the wave storms. Further, they do not undergo significant unit breaking fractures nor do they lose stability, and any errors in design usually increase armor erosion but rarely lead to the complete destruction of the breakwater. However, these are units which have serious drawbacks as regards face-to-face fitting, which can result in significant permeability changes when the packing density increases in the lower areas causing a displacement of armor units from the upper areas (heterogeneous packing). Face-to-face fitting can also result in a reduction in friction with the underlayer and other problems derived from a certain self-arrangement of the armor units which should be placed and maintained in a random position. The group of complex armor units with random placement includes the socalled "Tetrapod" armor units, which have a higher stability coefficient as a result of their resistance due to interlocking. Nevertheless, the ease with which these units break if they are too large is considered a major drawback. They are brittle and are not resistant to large unit movements; therefore, any error in the design wave storm may lead to the unexpected complete destruction of the breakwater in the first intense storm after construction. The group of armor units with non-random placement (b) in a single layer includes the so-called "Accropode" and "Core-Loc" armor units which have a good interlocking between units, but have a relatively brittle structural performance because when any of the units fail, a progressive failure takes place. These armor units require less concrete but they must be placed with great care. Any error in the construction or calculation of the design wave storm can lead to the total destruction of the structure. Finally, the armor units with regular uniform placement (c) may be either simple in shape like the so-called "Seabee" or "Hollow" shapes or more complex in shape such as the "Cob" or "Shed" ones. These units are usually placed in a single, uniform layer and their resistance depends fundamentally on gravity, friction and interlocking between the armor units, forming an assembly. As in the 2 ; AMENDED 1 previous case, these armor units are also quite resistant at the start of damage due to the tight interlocking between armor units, but they have a very brittle structural performance because they tend to present a progressive failure to destruction if any of the armor units fail. Focusing on the armor units with random placement, and more specifically on the mentioned cubic and parallelepiped blocks which, as stated earlier, are robust and easy to manufacture and are used along many coasts such as those of Spain, these units have serious drawbacks due to face-to-face fitting or selfpacking arrangement. The reason is the parallelepiped design tends to pack armor units in the lower areas with small movements, forming armor layers with many planar faces coupled in the critical areas at sea level, decreasing the water friction on the slope of the mound and thus allowing a higher run-up and overtopping and even the flooding of the rear side of the breakwater if the wave is very large. Description of the Invention The armor unit described in the present invention, being of the cubic and parallelepiped type usually manufactured for random placement, effectively solves the aforementioned drawbacks, and is considered an excellent solution for problems related to the self-arrangement and the decrease in friction. Specifically, the improvement is achieved by means of cubic or parallelepiped armor units which feature protrusions to prevent coupling between the faces of the armor units and to diminish their tendency to self-arrangement while, at the same time, increasing the friction with the underlayer, which implies a reduction in run-up and overtopping rates. Said protrusions, which are located centered in both a length direction and a height direction on the face of the unit and which can also have different shapes, such as a frustoconical or truncated pyramidal shape. These different shapes of said protrusions provide the unit greater friction with the underlayer, made of natural or artificial quarrystone, because said protrusions tend to penetrate into the underlayer, generating a passive resistance which clearly improves the tendency of the cubic or parallelepiped blocks to place the faces 3 AMENDED 1 parallel to the underlayer layer with an increased degree of friction between layers. In addition to the increased friction with the underlayer, the said protrusions of the armor unit prevent the face-to-face fitting caused by the movements of the armor units during the structure's lifetime, which leads to selfarrangement and reduces the porosity of the lower areas of the armor layer. Preventing the face-to-face fitting in the lower areas of the armor layer and the corresponding porosity reduction, the downward armor unit displacement is reduced as well as the displacement of armor units from the upper area, near the water level, which has an effect similar to erosion due to armor unit extraction. The reduction or suppression of the heterogeneous packing problem in the armor layer maintains the high hydraulic resistance capacity of the armor layer to armor unit extraction caused by wave attack. Finally, another advantage of the invention is related to the possible fracture or erosion of the protrusions over time which results in a conventional cubic or parallelepiped unit; therefore, at the very least the invention will have the stability and robustness features of those conventional armor units. Description of the Accompanying Drawings To complement the description herein and to enhance the understanding the features of the invention according to a preferred practical embodiment thereof, a set of drawings is attached as an integral part of said description, in which the i ' following is shown with an illustrative and non-limiting character: j Figures 1 a and 1 b show a perspective view and a cross-section of the armor unit of the invention in a cubic embodiment, the protrusions of which are formed by truncated pyramids with a square section.

In a preferred embodiment, the dimensions of the protrusions (1) are small
