Claim 10:
11. A fiber sheet system for perimeter sediment control, slope length shortening, and check dam applications, the fiber sheet system comprising:
a fiber sheet comprising a top side, a bottom side opposing the top side, a front side extending between the top side and the bottom side, a rear side opposing the front side and extending between and connected to the top side and the bottom side, a right side, and a left side opposing the right side, wherein the front side and bottom side define a lower front edge, wherein the rear side and the bottom side define a lower rear edge, wherein the front side and the top side define an upper front edge, wherein the rear side and the top side define an upper rear edge, wherein the fiber sheet comprises a coir fiber felt, wherein the coir fiber felt exhibits an area density in the range of about 1.25 kg/m2 to about 1.56 kg/m2, and wherein a ratio of a front side height of the front side of the fiber sheet to a top side width of the top side of the fiber sheet is in a range of about 9 to 1 to about 36 to 1;, and,
a netting contacting the fiber sheet, wherein the netting comprises a mesh comprising coir fibers, wherein the netting comprises a front side netting section and a rear side netting section, wherein the front side netting section contacts the front side of the fiber sheet, wherein the rear side netting section contacts the rear side of the fiber sheet, wherein the front side netting section comprises a front side netting edge, wherein the rear side netting section comprises a rear side netting edge, wherein the front side netting edge is aligned intermediate between the upper front edge and the lower front edge of the fiber sheet, and wherein the rear side netting edge is aligned intermediate between the upper rear edge and the lower rear edge of the fiber sheet, wherein the front side netting section exhibits a front side netting thread count, and wherein the rear side netting section exhibits a rear side netting thread count, and wherein the rear side netting thread count is greater than the front side netting thread count.
