1. A mold for making a revetment mat wherein the mold comprises:
an array comprising a plurality of casting impressions;
each of said plurality of casting impressions configured to receive and retain a composite fill, said plurality of casting impressions each having a closed bottom surface having a surface area and an open top surface defined by a border surrounding said open top surface; each of said plurality of casting impressions further comprising a plurality of impression walls extending between said closed bottom surface and said open top surface, wherein said impression walls are angled relative to said closed bottom surface and said open top surface to create a surface area of said open top surface larger than said surface area of said closed bottom surface;
wherein said plurality of casting impressions are arranged in a plurality of parallel rows to form said array, wherein the casting impressions in a first of said plurality of rows and the casting impressions in a row adjacent to said first row have impression walls that face each other and wherein said facing impression walls angle away from each other from the perspective of the open top surface of each casting impression;
wherein said borders surrounding said open top surfaces of said plurality of casting impressions within said array are coplanar, said coplanar borders forming an upper surface of said array;
a frame having an upper surface and a lower surface, wherein said lower surface of said frame is configured to removably rest over said upper surface of said array, said frame comprising a plurality of interlocking columns and rows arranged to define a plurality of casting passages, said interlocking columns and rows sized and positioned to align with said borders surrounding said open top surfaces of said casting impressions when said frame is in place over said array, wherein said interlocking columns and rows and said borders are configured to combine to form a plurality of barriers surrounding each of said plurality of casting impressions when said frame is in place over said upper surface of said array, wherein said plurality of casting passages in said frame provide a fluid connection to said plurality of casting impressions when said frame is in place over said array, and wherein said barriers are configured to retain fill between said upper surface of said frame and said open top surface of each of said plurality of casting impressions when said frame is in place and said casting impressions are full and wherein each of said plurality of casting passages substantially match the surface area of one of said open top surfaces of said casting impressions when said frame is in place over said array.
