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.

The present invention relates to a new artificial surfing reef construction method, using geosynthetic cementitious composite mat, with a top coating of plasticized gypsum composition. The current invention artificial surfing reef construction method, can be built in surfing lakes, water basins, pools, lagoons, ponds, reservoirs, rivers, streams and bodies of water.

A tidal flood mitigation assembly includes a riser that is attachable to a well head located in a coastal area. The riser extends at least 5.0 feet above ground to elevate the entry into the well head high enough to inhibit king tide flood waters from pouring outwardly from the well head. In this way the riser can mitigate king tide flood waters. A discharge pipe is fluidly coupled to the riser and the discharge pipe is in fluid communication with a sump pump. In this way the discharge pipe directs water from the sump pump into the well head. A breather tube is fluid coupled to the riser for purging air from the riser when the water level rises in the riser.

A sediment control system including a first barrier element. The first barrier element has a first end, a second end, a front side, a back side, a bottom side and a top side. The sediment control system also having a second barrier element. The second barrier element has a first end, a second end, a front side, a back side, a bottom side and a top side. The first end of the first barrier element cooperating with the first end of the second barrier element to prevent the separation of the first and second barrier elements. A barrier includes a first end and a second end wherein the second end is disposed a certain length from the first end. The barrier element also has a front side and a back side wherein the back side is disposed a total depth from the front side. The barrier element further includes a bottom side and a top side wherein the top side is disposed a certain height from the bottom side. The barrier element has a generally triangular cross-sectional shape perpendicular to the length of the barrier element. A method of controlling soil from a disturbed area from being transported to undesired locations using the sediment control system.

A shoreline restoration method utilizes a plurality of apparatuses facilitating the formation of a vertical oyster reef. Each apparatus includes a rod frame and a plurality of individual mesh bags are positioned between an inner and an outer frame. The inner and outer frames include top and bottom frame portions and a plurality of side support frame members extending there between. Each individual mesh bag is aligned with at least one outer side support frame member and at least one inner side support frame member and wherein each individual mesh bag is coupled to an adjacent mesh bag. A plurality of cross ties extends between the inner frame and the outer frame and cultch material fills each individual mesh. The shoreline restoration method promotes shell accumulation and expands the tidal zone.

A bio-friendly water flow control system can include a portable structure adapted to contain organic waste material. The water flow control system can be configured for deployment outdoors to guide water flow to limit erosion. A portable structure of such a system can include a sheath that is configured to contain waste material within an interior of the sheath. The portable structure may be configured to allow a flow of water into the interior of the sheath. The portable structure may include a waste material that includes processed palm frond particles. The portable structure may be configured to absorb a weight of water at least 50% greater than a dry weight of the portable structure.

The invention relates to a device for forming concretions in an electrolytic medium by electrolysis, which comprises an anode 110 and a cathode 120 submerged in the electrolytic medium and a regulating circuit 100 configured to regulate an electrolysis current in order to form concretions on the cathode 120.

The anode 110 and the cathode 120 are used as a current source for supplying the electrolysis process and are connected in the regulating circuit by at least one regulating element capable of limiting the electrolysis current.

Provided is a water-absorbent resin that quickly absorbs water, even in sandbag in which a large amount of the water-absorbent resin has been used, that does not easily form unswollen lump, and that has a high gel swelling volume when water is used to swell the water-absorbent resin. This water-absorbent resin is configured from a polymer of water-soluble ethylenic unsaturated monomers. The physiological-saline absorption capacity of the water-absorbent resin is 40-60 g/g. When a cross-sectional image of the water-absorbent resin is observed by x-ray computed tomography, the fraction of the area of the cross-sectional image that is hollow portions (the hollow area ratio of the cross-sectional image), as calculated on the basis of formula (I), is no more than 10%. (I) Hollow area ratio [%]={total cross-sectional area (B) of hollow portions of the water-absorbent resin/(total cross-sectional area (A) of resin portions of the water-absorbent resin+total cross-sectional area (B) of hollow portions of the water-absorbent resin)}×100%.
