The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

A system for stabilization of a shoreline comprising a sheet having an unfolded state and a folded state, the sheet comprising a first edge and a second opposing edge connected by a first end and a second end, the sheet comprising a first layer formed from a first degradable fabric and a second layer formed from a second degradable fabric, the sheet further comprising channels formed at each of the first edge and the second edge, the channels formed from one or more of the first and the second fabrics, each of the channels comprising an anchor rope threaded therethrough, and each of the channels comprising a plurality of openings, wherein the anchor rope extends through the plurality of openings for securement to a shoreline surface by the anchor rope, and methods of using the same.

A fiber block system suitable for controlling erosion and stabilizing soil is described that comprises a fiber block formed of a densely packed natural fibers and having an apron extending therefrom, wherein the apron is formed of the same natural fibers. The fiber block and apron are enclosed in a sleeve of fiber mesh and ties are disposed in the fiber block and connect to the sleeve. The fiber block, mesh, and ties can be made of coir fibers.

An erosion control roll comprises a porous outer casing having an interior, a fill material within the interior, wherein the fill material comprises a mineral wool. The erosion control roll is flexible and positionable where it can provide one or more of erosion control, sediment separation, water flow diversion, and a fire barrier.

An erosion-preventing laminate mat may include a first layer of slivers of a natural material, a second layer of slivers of a synthetic material, and, in embodiments, a third layer of an open mesh. A system for utilizing the erosion-preventing laminate may include a movable frame having an upper surface shaped to pass beneath a substantially flat sheet of tied block mat, the frame including a spindle below the upper surface for supporting a roll of the first mat, the first mat including the first layer of slivers of a natural material, the second layer of slivers of a synthetic material, and the third layer of an open mesh. In embodiments, a system for forming the mat includes a movable frame shaped to pass beneath a substantially flat sheet of the tied block mat, and including a spindle below the upper surface for supporting a roll of the first mat.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

A river course ecological treatment system essentially comprises a plurality of ecological biological water purification systems and a plurality of plastic retaining dams disposed along a river course, and at least one damp land ecological water purification system disposed beside the river course. The plastic retaining dams separate the river course into several retaining regions. The ecological biological water purification systems purify the water in the retaining regions by microorganism purification. Afterward, the water purified by the ecological biological water purification systems is introduced into rainwater channels of the at least one damp land ecological water purification system. After being purified by aquatic plants in the at least one damp land ecological water purification system, the water returns to the retaining regions the downstream portion of the river course. Therefore, a river improvement system capable of performing both step-by-step treatment and joint treatment is effectuated.

A Composite Filter Sock Assembly includes a Compost Filter Sock and Secondary Tubular Seam Filling Device configured to be wedged beneath the compost filter sock, whereby the compost filter sock provides a pinning pressure to the Secondary Tubular Seam Filling Device and wherein the compost filter sock has a nominal diameter of 2-12 times a diameter of a tubular element of the Secondary Tubular Seam Filling Device. The Tubular Element may be least partially filled with a swell-able material such as sphagnum peat moss and may include a fastening mechanism on an exterior surface configured to facilitate coupling to a mesh tube of a compost filter sock.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

Disclosed are a method, device and system of a watershed stormwater management through a biobased biodegradable nutrient and sediment retaining water filtration tube with erosion control. In one aspect, a method of watershed stormwater management system includes forming the biobased filtration tube from a nontoxic renewable domestic agricultural material. The method ensures a diameter of the biobased filtration tube to approximately 10% greater than a field deployment to prevent shrinkage caused by ambient conditions, retains a sedimentary pollutant, and places the biobased filtration tube along the perimeter of a site. A filter material of the biobased filtration tube helps preventing high concentrations of sedimentary pollutant from getting into the streams. The biobased filtration tube captures and treats stormwater that runs off as sheet flow. The biobased filtration tube is utilized in the vegetated form. Vegetation grew into a slope at the site anchors the biobased filtration tube in an environment.
