1. A revetment block adapted for being cabled to one or more neighbor revetment blocks of similar construction, said revetment block comprising: a body constructed of a heavy material; the body of said revetment block having a bottom portion with substantially vertical side surfaces, and a top portion having inwardly beveled sides that facilitate articulation between neighbor revetment blocks; a pair of cable channels extended through the body of said revetment block; two spaced-apart guide slots formed in one side surface of the bottom portion of the body of said revetment block; two spaced-apart guide ribs formed in an opposite side surface of the bottom portion of the body of said revetment block; said two spaced-apart guide ribs are formed only in the bottom portion of the body of said revetment block so that there is reduced engagement of the guide ribs of one revetment block with the respective guide slots of the neighbor revetment block as the neighbor revetment block articulates in a direction where the respective beveled top portions of the revetment block and the neighbor revetment block become closer; the two guide ribs of said revetment block adapted for being engaged in two respective guide slots of one said neighbor revetment block when configured in a side-by-side arrangement of revetment blocks of a first type mat, and the pair of cable channels of said revetment block align with the respective cable channels of the neighbor revetment block to form said first type mat; and one guide rib of said revetment block adapted for being engaged in a guide slot of one said neighbor revetment block and the other guide rib of said revetment block adapted for being engaged in a guide slot of another said neighbor revetment block when configured in a staggered arrangement of revetment blocks of a second type mat, and a first cable channel of the pair of cable channels of said revetment block aligned with one cable channel of said one neighbor revetment block and a second cable channel of the pair of cable channels of said revetment block aligned with one cable channel of said another neighbor revetment block to form said second type mat.
