Disclosed are exemplary embodiments of sediment/erosion/perimeter control devices and methods of making and using the same. In exemplary embodiments, a sediment/erosion/perimeter control device (e.g., a wattle, etc.) comprises a material configured such that the sediment/erosion/perimeter control device is reconfigurable between at least a first configuration and a second configuration. In the first configuration, the sediment/erosion/perimeter control device has a first size, shape, volume, and/or weight. In the second configuration, the sediment/erosion/perimeter control device has a second size, shape, volume, and/or weight substantially larger than the corresponding first size, shape, volume, and/or weight that the sediment/erosion/perimeter control device has in the first configuration.

Drainage liners and geomembranes including the drainage liners are disclosed herein. The drainage liners have a woven scrim made of warp tapes and weft tapes, and have a plurality of high-denier strands each superimposed upon a warp tape or each superimposed upon a weft tape and each interwoven into the woven scrim by oppositely oriented tapes. The warp tapes or the weft tapes with superimposed high-denier strands thereon are spaced apart within the woven scrim by at least one tape of a same orientation, thereby defining a plurality of parallel channels for fluid flow between nearest neighboring high-denier strands.

Disclosed are exemplary embodiments of sediment/erosion/perimeter control devices and methods of making and using the same. In exemplary embodiments, a system comprises a convertible silt fence/scour pad and a wattle. The wattle is integrated with the convertible silt fence/scour pad such that the convertible silt fence/scour pad and the wattle are an integrated, singular, or unitary product. The convertible silt fence/scour pad is deployable in at least a first orientation and a second orientation. In the first orientation, the convertible silt fence/scour pad is generally vertical and/or generally perpendicular relative to the ground or other surface supporting the wattle, whereby the convertible silt fence/scour pad is operable primarily as a silt fence. In the second orientation, the convertible silt fence/scour pad is generally horizontal and/or generally parallel relative to the ground or other surface supporting the wattle, whereby the convertible silt fence/scour pad is operable primarily as a scour pad.

The present invention relates to an intelligent bionic scouring protection structure for a cylindrical foundation and an application method thereof, wherein the protection structure is formed by connecting bionic units; an uppermost layer of the bionic unit is a bionic grass bundle, a bottom end of the bionic grass bundle is sleeved inside a bundle tube, the bundle tube is fixedly connected with a fiber mesh layer through a binding wire, connecting rings are fixed at both ends of the fiber mesh layer through the binding wire, two adjacent fiber mesh layers are connected through the connecting ring; and a bottom portion of the bionic unit is provided with a seabed connecting structure for fixing the whole protection structure. The above protection structure with an upper layer, a middle layer and a lower layer is adopted to replace traditional hard scouring protection such as ripraps and sand bags.

A geosynthetic mat comprises an upper and a lower cover layer and a middle filler layer arranged between the upper cover layer and the lower cover layer and consisting of a filler layer material comprising a swellable material. The top cover layer and/or the bottom cover layer consist of a biodegradable material or comprise a biodegradable material, the peel strength being characterised by a residual peel strength degree at a predetermined point in time after the start of the biodegradation process, which is formed by the square number of a quotient of a reduced peel strength, which the upper and lower cover layer and a connecting structure have at the predetermined point in time, to an initial peel strength, which the upper and lower cover layer and the connecting structure have before the start of a biodegradation process.
