A storm water runoff and erosion control device includes a rigid frame covered by a layer of mesh material. The frame defines an interior space that is filled with filtration material. The device may be configured as a wattle having an elongated frame with a triangular cross-section. The wattle may be extended along the contour of a hill to reduce erosion, or it may be placed at the entrance to a drainage inlet to slow the velocity of, and filter sediment and contaminants from, water entering the inlet. Alternatively, the device may be a compact filter that is a cube, cylinder, sphere, or other suitable geometry. A plurality of these compact filters may be placed in the basin of a storm water drain, and piled sufficiently high to cover the outlet from the basin. Thus, all the water in the basin must pass through the compact filters before exiting.

Disclosed is a sludge three-dimensional electroosmosis drainage reinforcing method based on a novel electric geotextile complex, and belongs to the field of soft soil foundation reinforcement. A novel electric geotextile complex is adopted, and a designed multidirectional three-dimensional continuous electroosmosis drainage method is adopted to perform rapid drainage reinforcement treatment on sludge, wherein the electric geotextile complex is prepared by combining fibers and conductive materials with a flexible drainage plate and has the effects of electric conductive, drainage, corrosion resistance and reinforcement. The proposed drainage method can realize the electroosmotic drainage in vertical and horizontal directions. Through layer by layer electroosmosis from bottom to top, the consolidation drainage effect of sludge in the lower layer can be enhanced by the increasing loading pressure from the upper sludge. After the vertical electroosmosis is completed, the method of exchange electrode is used to conduct horizontal electroosmosis in opposite direction.

A geomaterial web includes a first organic structural material and a second structural material that is different from the first structural material, which is bonded together with the first structural material to form a sheet-like composite material web extending in two mutually perpendicular directions. The first structural material and the second structural material are organic materials, where the first structural material has a first biodegradability and the second structural material has a second biodegradability that is different from the first biodegradability. The second biodegradability may be less than the first biodegradability.

Provided is a drainage grouting pipe and a method of use thereof. The drainage grouting pipe comprises a perforated steel pipe, a plurality of elastic anti-filtration geotextiles, a movable stopper, and a grouting pipe. The perforated steel pipe consists of a front conical tip, a middle grouting section, a rear hole-free section, and a steel pipe seal. The middle grouting section is provided with a plurality of grouting holes. The surface of the middle grouting section of the perforated steel pipe is seamlessly, and circumferentially wrapped by the plurality of elastic anti-filtration geotextiles, and gaps are formed between adjacent elastic anti-filtration geotextiles. Firstly, the geotechnical layer is drained by a pumping system, and then the grouting position in the geotechnical layer is located and controlled by pulling out the grouting pipe to control the plunging depth of the movable stopper, thus achieving the prevention and treatment of groundwater seepage damage.

Stormwater runoff and erosion control devices include carpets or blankets, wattles, and compact drainage filters. A carpet or blanket is a sheet of mesh material having a border formed of a different material than the mesh material. Wattles and compact drainage filters include mesh material supported by a rigid frame. In preferred embodiments, the mesh material includes biochar or activated carbon. Blankets and carpets may be positioned above or suspended below drainage grates in a storm water runoff system, and held in place by magnets. Wattles may be placed on hillsides, or between concrete barriers and drainage grates. Compact drainage filters may be placed at the outlets of catchment basins.
