1. A flood barrier component in the shape of a polyhedron comprising:
a bottom wall;
a plurality of side walls having a bottom edge and top edge, said bottom edge of said plurality of side walls coupled to an outer edge of said bottom wall;
a top having an outer edge thereof, said top edge of said plurality of side walls coupled to the outer edge of said top;
the plurality of side walls configured to be moveable between a collapsed position and an extended position;
in said extended position, said plurality of side walls, said bottom wall and said top defining a space therebetween;
at least a portion of said plurality of side walls or top is permeable to water, allowing water to enter the interior into the space;
wherein said top is formed of a material with a density less than that of water such that said top acts as a floatation device; and
wherein upon entry of water into the space, the positive buoyancy of the floatation device in the water, raises the floatation device to move the plurality of side walls from said collapsed position to said extended position; and
wherein said flood barrier component is configured to be portable.
