Below grade fluid containment structures, which may include a foam floor and a foam wall extending upward from the floor, the foam wall being formed from foam panels. A granular material is provided for reducing hydraulic soil pressure against an exterior face of the foam wall that would otherwise be exerted by the soil, if the soil were allowed to be positioned up against the foam, particularly the foam wall. The well-draining granular material may be gravel, crushed stone, or the like, which provides better drainage as compared to the surrounding soil material. The interior face of the foam is coated with an elastomeric abrasion resistant impact resistant polymeric coating that seals the below grade interior space defined between the floor and the wall in a seamless water-tight configuration.

A sediment capping system is adapted to create, and distribute, a homogenized mixture of capping material. Where distributing the capping material, the system is configured to militate against the capping material forming clumps of a size and weight that would disturb the sediment on a bottom of a body of water. This in turn militates against the sediment being disturbed, and a disturbing of pollutants and toxins into the water surrounding the sediment. The sediment capping system militates against the clumping of capping material through a vibrating spreader and baffle system, producing a sediment cap with a more consistent depth that will minimally disturb the sediment on the floor of the body of water where the sediment cap is being deposited.

The present disclosure relates to a method for building a farmland ecosystem with multiple mutual-benefit species in multiple habitats, and belongs to the technical field of agroecological environment. The present disclosure improves the resource utilization efficiency of the farmland ecosystem to the maximum extent, greatly reduces application of chemical fertilizer and pesticides, and reduces environmental damage and pollution. By means of different ecological niches of living things, a beneficial ecological service function is brought into play such that species in the farmland ecosystem can live in a suitable farmland microenvironment, competition for the same living space in the same place is avoided, and harmonious coexistence among the living things is realized; and food with high quality and a higher grain output value are provided.

An improved exclusion barrier including a plurality of elongate members extending in a generally upright condition between a sea floor and a sea surface. The elongate members are improved to provide a more uniform surface area for the prevention of sharks passing through upper portions of the barrier and maximizing the exclusion capabilities of the overall barrier network. The elongate members include, in addition to permanent magnets, hydro-electric power generation mechanisms for powering electro-magnets within the elongate members to produce a stronger electro-magnetic deterrent field across the barrier network, and also include telescoping mechanisms to allow for a variance in length of each member in coordination with changing wave and water levels and to provide additional pump action for hydro-electric power generation within each elongate member. The exclusion barrier is also secured to the sea floor by an anchoring base having evenly spaced anchoring locations.

A method for building a farmland ecosystem with multiple mutual-benefit species in multiple habitats is provided. The method includes: marking out an ecological field plot for planting crops in a farmland, arranging one to three earthworm breeding strip stack(s) at equal intervals, and marking out different planting areas; digging an ecological field ditch surrounding a periphery of the ecological field plot, and planting aquatic plants and breeding aquatic animals in the ecological field ditch; surrounding a periphery of the ecological field ditch with an ecological wide ridge, planting forage plants on a ridge surface of the ecological wide ridge, and planting arbors on an outer side of the ecological wide ridge; and arranging an ecological pond on a drainage side of a hole, wherein aquatic plants are planted in the ecological pond, and crustaceans are bred in the ecological pond.
