CASE STUDY The USDA, Natural Resources Conservation Service (NRCS) Bloomsburg Technical Office was contacted to assess a 1,020 foot waterway on the Ray Levan crop and poultry farm located along SR 42 in Columbia County, PA that was experiencing severe channel erosion. The established waterway was not previously provided with a channel liner. Four cross-slope diversion terraces and an upslope non- porous drag-strip drained into the eroded waterway. SITUATION USDA Natural Resources Conservation Service Bloomsburg,PA The property owner agreed to redefine the eroded waterway into a 20-foot wide parabolic channel. The waterway was designed to safely convey a 10-year design storm from a 30-acre watershed with a flow of 110 cubic feet/second and velocities ranging from 6 to 11 feet/second. The waterway was regraded to the designed dimensions and topsoil was placed in the channel, fertilized and seeded. The owner chose two types of East Coast Erosion Blankets Turf Reinforcement Mats (TRMs) for channel liners. ECSC-3 Triple Net Straw/Coconut Turf Reinforcement Mats (TRMs) were installed in the lower 450-foot reach of the waterway. ECP-2 Double Net Polypropylene TRMs were installed in the upper 570-foot reach of the waterway. Shorter lengths of the ECP-2 TRMs were installed at the outlets of the four diversion terraces to safely convey flows into the waterway. ECS-1D Temporary Single Net Straw erosion control blankets were installed on both side slopes parallel to theTRMs for the entire length of the waterway. A total of 2,800 square yards of rolled erosion products were installed on the project. SOLUTION Erosion problems were resolved and use of the TRM allowed the installation of a channel with reasonable dimensions without the need to go to a much more costly rock lined channel. The waterway vegetation was fully established at 30 days (bottom right photo).
