Disclosed are embodiments of a method for manufacturing concreate panels for a mechanically stabilized earth (MSE) retaining wall that employ geosynthetic strips that attach to the MSE retaining wall and extend into the backfill soil. One embodiment can be generally summarized as follows: (a) providing a mold for the concrete panel; (b) providing in the mold: (1) a plastic pipe; (2) a metal rod situated in the pipe; (3) a removable block-out insert that creates a geosynthetic strip cavity within the panel body around the pipe for enabling a geosynthetic strip to be looped around the pipe; (c) introducing concrete into the mold; (d) permitting the concrete to substantially solidity within the mold; and (e) after the concrete has substantially solidified, separating the panel from the mold and removing the block-out insert to expose the cavity and the pipe extending through the cavity.

A ditch check system and methods for storm water control are provided. The ditch check system can include a velocity-restricting component of non-woven geotextile fabric with one or more porosities configured to control the velocities of storm water flows for sediment control and silt retention. The velocity-restricting component can have one or more reinforcing elements to provide additional support to protect against tearing and/or undue movement of the fabric, as well as provide attachment points for fasteners used to fasten the fabric to support members. The ditch check system can further include a front water seal and a rear scour guard attached to the velocity-restricting component at ground level which are substantially impermeable to vertical water flow to inhibit ditch scouring and prevent the flow of storm water under the ditch check system. To facilitate transportation, installation, and assembly, one or more of the components of the ditch check system can be supplied as a pre-assembled package.

Systems and methods of restoring a lake including dredging, island creation, water treatment, real estate development, computer modeling of environmental conditions, wave height reduction, sediment removal and encapsulation, bathymetry contouring, littoral zone restoration, plant restoration, and/or fish restoration.

The present invention is directed to a horizontally extendable silt fence. The present invention is also directed to a silt fence system comprising a horizontally extendable silt fence comprising a water permeable geotextile material having an upper edge and a lower edge, and a plurality of posts comprising an upper portion strutted and arranged to be coupled with the upper edge of the water permeable geotextile material, a lower portion structured and arranged to be coupled with the lower edge of the water permeable geotextile material, and an anchor portion structured and arranged to be driven into the ground to anchor the post. Also disclosed is a method of filtering silt from a fluid stream.

The invention belongs to ecological revetments in the technical field of river ecology, which particularly involves an ecological revetment to regulate wandering rivers. The ecological revetment is composed of porous concrete-piles, ecological connecting-plates, an ecological viewing-corridor and a slope green-belt. The ecological landscape-corridor and anchor rod are placed on the upper and middle parts of the pile structure, respectively. In virtue of the innovative structure, the ecological revetment will strengthen the revetment structure, reduce the revetment settlement, prevent the revetment from moving, and enhance the overall stability of the revetment project. The ecological holes exist on the ecological connecting-plates, which is beneficial to the exchange of material and energy from the river course and the bank slope, and the holes could greatly enhance the self-cleaning capacity of the water body. Not only do the plants on the ecological viewing-corridor provide the habitats for the organisms, but also green the revetment.

A silt barrier support system broadly comprising a number of vertically extending posts, a number of silt barrier attachment devices, a number of end silt barrier attachment devices, and an inward silt barrier attachment device. The silt barrier attachment devices include vertical barbs for vertically retaining portions of an upper end of a geotextile fabric layer on upper portions of the posts. The end silt barrier attachment devices include horizontal barbs for laterally retaining end portions of the geotextile fabric layer on end posts. The inward silt barrier attachment device includes first and second sets of horizontal barbs for removing lateral slack from inward portions of the geotextile fabric layer.

Disclosed is a device for containing granular elements, comprising a metal mesh panel having metal wires welded together, the panel comprising at least one curvature of a first orientation and at least one curvature of a second orientation, the first orientation being characterized by a first axis and the second orientation being characterized by a second axis, the first axis and the second axis being non-collinear.

A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for a job site. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for a job site.

An erosion, sediment and pollution control product comprises a geotextile which includes cellulose based threads treated to be hydrophobic and cellulose based filler within the tubular geotextile. The geotextile may be knitted and may include lyocell threads and wherein the lyocell threads are treated to be hydrophobic, and are treated with food grade mineral oil. A method of making a tubular knitted geotextile comprises the steps of: supplying cellulose based threads to a circular knitting machine and knitting a tubular substrate, treating the cellulose based threads with one of mineral oil, beeswax, paraffin, petroleum jelly, lanolin, plant-based oils, and combinations thereof, whereby the threads are rendered hydrophobic.
