1. A sediment-control fence comprising an anisotropic fabric having a lower grade line and an upper edge defining an installed height extending between the lower grade line and the upper edge, the anisotropic fabric comprising fibrillated yarn running in a transverse direction substantially parallel with the installed height, and fibrillated yarn running in a machine direction substantially parallel with a length of the anisotropic fabric, wherein a tensile strength of the anisotropic fabric in the machine direction remains substantially constant along the installed height.
