ABSTRACT:
The erosion control system of the present invention typically includes at least first and second primary elements each having at least three sides and a height H. Each primary element includes a truncated conical aperture located in alignment with the midsection of each side and set back into the interior of each primary element. The conical aperture includes a lower diameter d.sub.1 and an upper diameter d.sub.2 less than d.sub.1. A link interconnects the first and second primary elements and includes a height h<H. The link includes first and second truncated conical end sections each having a lower diameter d.sub.3 .ltoreq.d.sub.1 and an upper diameter d.sub.4 .ltoreq.d.sub.2. The conical side surfaces of the end sections are oriented generally parallel to the conical side surfaces of the apertures of the primary elements. A strut is coupled to the first and second end sections of the link to maintain a fixed distance between the end sections.
