oil erosion is a major environmental threat to the sustainability and productive capacity of agriculture. During the last 40 years, nearly one-third of the worlds arable land has been lost by erosion and continues to be lost at a rate of more than 10 million hectares per year. With the addition of a quarter of a million people each day, the world population's food demand is increasing at a time when per capita food productivity is beginning to decline.

 Geotextiles have replaced graded granular filters used beneath riprap or other armor materials. Typical applications include drainage channels, shorelines, river, coastal protection, canals, and bridge and pier scour protection systems. The effective control of destructive erosion in shorelines, riverbanks, drainage ditchres, and canals has always posed a difficult problem. This stems from the need for a robust outer protective layer to absorb the energy of wave or current, and an inner protective layer, traditionally in the form of an aggregate filter to prevent erosion of the bank soil. This inner layer has a particularly difficult role to play, since it must fill the often conflicting requirements of being fine enough to act as a bank soil filter, yet coarse enough to prevent the generation of high differential pressure between the bank and external water levels. These problems are overcome with properly designed Geotextile filter fabric installed to cover the exposed surface of the bank. The selection of geotextiles used in shoreline erosion control requires consideration of filtration mechanisms, installation stresses, and long-term durability requirements. Filtration mechanisms will rely on the gradation of the soil, pore size characteristics of the geotextile, and water flow conditions. While design criteria have been well established for geotextile filters, the special nature of erosion control applications must be carefully considered in selecting the most appropriate geotextile for the specific site conditions. The design relations are complicated by the reversing flow conditions that exist in coastal erosion control applications.

 Grass Mulch is a natural grass straw fiber mulch, produced byGrass Fiber, Inc. @ (541) 998-3261 using clean grass seed straw from certified grass seed fields. Grass Mulch is disc refined and heat processed in such a manner to contain no growth or germinating factors. Grass Mulch disperses rapidly in water and remains in unform suspension under agitation. It blends with seed, fertilizer and other approved and specified materials to form a homogeneous slurry. When applied by hydraulic means to ground surfaces the fibers will physicaly intertwine to form a strong moisture holding mat that will assist soil erosion control and provide percolation as well as favorable micro-climate conditions to aid seed germination and growth. The fibers are clored green with a water soluble non-toxic dye to assist the operator in applying Grass Mulchuniformly. The dye will not stain concrete, asphalt, masonry or painted surfaces. The Turf Mulchis commonly used in a dry roll on application as a top dressing for newly seeded lawns.

 In a Slope Stabilization application, for any given soil at a certain moisture content, there is an angle beyond which the soil will not stand without some kind of support. Whenever the steepness of the slope exceeds this failure angle, gravitational forces act on the soil mass to create shear stresses causing the slope to fail through sliding or sloughing off. The process ends when a new equilibrium is achieved at an angle less steep than the initial one. In many situations, it is desirable to have a slope steeper than the shear strength which the soil will allow. One method employed to achieve this objective to provide reinforcement at specified increments back into the slope. The resulting reinforcement increases the effective failure angle, preserving the stability of the slope.

 TerraGuard  "Providing Maximum Erosion Protection through Vegetation Establishment"

 Retaining walls are structures built for the purpose of stabilizing very steep slopes using minimal land area. A common example is to infill the side of a hill to build or widen a road. The slope created is so steep as to be unstable and requires a retaining wall to prevent slope failure retaining walls.  There are two basic types of retaining walls: A CANTILEVER retaining wall is usually made of reinforced concrete and acts as a structural member. A GRAVITY retaining wall has a vertical or near vertical face and its ability to retain soil behind it depends upon gravity (its own weight). This type of wall is usually composed of unreinforced concrete or soil. If made of soil, the wall generally consists of a facia and one or more layers of reinforcing members extending from the facia back into the soil mass.  The functions of the facia  are to prevent soil from sloughing off the surface of the wall and to prevent erosion of the face of the wall.  The function of the reinforcing member (TerraGrid) is to increase the "effective" thickness of the wall which increases its stability.  The wall itself must be built to withstand pressures applied by the retained soil. This force, "lateral earth pressure', is dependent upon several parameters, including the geometry of the wall and the characteristics of the retained soil, such as its unit weight and angle of internal friction. In designing a retaining wall, it is necessary to consider potential forces that could cause wall failure and compare them to the stability calculations of the proposed wall, taking into account generally accepted safety factors.  TerraJute is a light-weight woven polypropylene fabric designed to control erosion during vegetation establishment. It covers sees and soil-protecting against wind and rain while allowing the passage of moisture and sunlight. As new vegetation grows, TerraJute slowly degrades from exposure to sunlight".  TerraGuard turf reinforcement mats are an aesthetically pleasing, alternative to rigid systems such as concrete or riprap. TerraGuard is a permanent erosion control product comprised of polypropylene fibers sewn between two nets."  TerraTex GS, HD and GS-150 are rugged woven fabrics used to stabilize very poor to moderate strength soils by seperating subgrade and aggregate layers." TerraCell is a cellular confinement system providing innovative solutions for ground stabilization, slope protection, erosion control and retaining walls. It is constructed of high-density polyethylene strips ultra-sonically bonded together to form a high-strength network of cells. These cells confine and reinforce all types of fill material. The TerraCell system can often replace expensive or elaborate construction methods. TerraCell is available in various heights in standard or large cell configurations."

 Reno Mattresses consist of rectangular units, fabricated from a double-twist, hexagonal mesh of soft annealed, heavily zinc coated wire.   Filled with stone, Reno mattresses are flexible and permeable elements from which a broad range of structures may be built (river bank protections, channel linings, etc.).  Terramesh® System is a soil reinforcement system used to stabilize soil embankments, slopes, and walls. Rolls of double-twist, hexagonal mesh are often used to prevent rock and debris from falling onto roads and railways.   Hexagonal wire mesh has long service life and high strength to meet the strict requirements for this type of work. The double twist weave is strong enough to withstand the force of falling rock and, unlike chain link mesh, will not unravel should some of the wires break. The rolls or panels also feature a selvedge wire of larger diameter than that used for manufacturing the mesh.

 Woven Coir Fibre Geotextiles are made to matrix by running the yarns in warp and weft direction forming open mesh matrix. The open area will vary according to the number of  warp and weft yarn running in a specified area. The woven erosion control mats can be made out of either coconut coir yarn or high tensile bristle machine spun coir twine. The characteristics of these two grades of  geotextiles are as follows:- high wet tensile strength and functional longevity of 2-4 years combined with heavier weight is suitable for use in steep slopes and in channels with high flow velocities and high shear stresses.  Coir Twine Geotextiles -due to its high tensile strength and functional longevity of 5-7 years, these mats can be used in very steep slopes and in channels and ditches with shear stresses up to 5  lbs./sq. ft(240n/m2). This type of blanket, which is referred to as turf reinforcement mat (trm), is an ideal substitute for 100% synthetic blankets.
