Assemblies and methods for securing an elongate apertured fence to the ground. The fence includes an upper section which is apertured and which extends upwards from the ground, and a lower section which may or may not be apertured and which is not buried in the ground. The lower section is contacted by a footing member which is secured to the ground and which stabilizes the fence along a desired line along the ground. In some embodiments, the lower fence section is parallel to the ground, and at least part of the footing member lies between the lower fence section and the ground.

Technologies and techniques that reduce cost and time for propagation, transplantation and harvesting of Vetiver Grass for multiple applications. Tools, equipment, systems and processes to propagate, transplant and harvest Vetiver Grass that will promote the rapid implementation of sustainable, large-scale Vetiver plantations in wealthy and impoverished countries alike.

The disclosed systems, methods, and apparatuses may combat coastal erosion using a shell module shaped to enable retention of sand on a beach and shore face. The shell module may be shaped to minimizing interference with recreational use of the beach and providing a beneficial environment for desirable sea life. The modular shell can be conveniently transported and emplaced in shell reefs. These shell reefs may comprise multiple, optionally interlocking shell modules. These shell reefs can prevent fill, such as sand, de-watered sand, or sand slurry from being scoured and sluiced out to sea. The disclosed systems and methods harness the energy of incoming and returning waves, including tidal and surf action, to assist in spreading the fill, recreating a natural beach, complete with layers of sand capable of resisting the scouring force of ocean waves and currents.

An energy dissipater comprising a plurality of periodic hyperbolic surfaces, forming a continuous surface-structure, and enveloping contiguous tunnels there through.

This disclosure provides methods, systems, and kits for building seawalls using mechanically interlocking blocks. The interlocking blocks have interiors that can be filled with sand, gravel, or cementitious material after formation of a wall. The interlocking blocks that can be connected on any side to form a structure, wall, foundation, floor, building, flotation device, gardening structure, or toy. The interlocking blocks typically comprise center openings and connecting openings on each side and can be connected with hardware through the connecting openings. The center openings allow for materials such as pipes, wires, conduit, and rebar to pass through interlocked blocks. Connected blocks can also be filled with fortifying material to strengthen the structure. Sides of connected blocks can be covered with faceplates to direct flow of fortifying material and aid in the creation of desired configurations. Also provided are connectors for connecting sides of the interlocking blocks.

A portable, water-filled barrier system includes a water-fillable module that is internally divided into cells that emulate a section of a sandbag dike or wall, the module being fixed to an underlying base having front and rear boundaries that extend up from base and horizontally restrain the module. The base can be flexible and water filled, or rigid, and can be installed at or below grade. A lid can extend between the front and rear boundaries of a rigid base to cover the unfilled module, enabling the assemblies to be stacked when stored and transported. The lid can be hinged and, when open, can be supported by at least one brace extending from behind the lid to underlying terrain, where it can be wedged or staked in place. Adjacent bases can be joined at the front and rear to maintain contact between adjacent modules.

The present invention provides a low-energy coastal beach restoration method, comprising: constructing a convex beach berm, determining an aspect ratio of the beach berm edge, determining a beach face slope, performing sand replenishment, determining the dredging zone and dredging depth, and determining the steps of building a sediment groin. The present invention utilizes the feature of the convergence effect of the wave energy on the headland, artificially constructs a convex headland shaped beach berm, and determines the required beach face range and slope according to the convex beach berm edge. During beach restoration, dredging around the beach face, while reducing mud sources and increasing the nearshore water depth, it also builds a convex nearshore terrain, which effectively increases the wave energy at the restoration site and improves the coast muddy situation of low-energy coasts.
