The invention discloses an unpowered water purification system for a riverfront landscape constructed wetland, comprising a riparian wetland constructed along a lake-land ecotone of a river, lake-pond. The riparian wetland comprises a plurality of alternatively arranged wetland islands and watercourses formed between them. The bottom surface of the riparian wetland is lower than the normal water level of the river, lake-pond, and the upper surface of the wetlands is flush with the normal water level of the river, lake-pond. Plants are planted on the wetlands. A revetment is constructed between the riparian wetland and the river, lake-pond, and its upper surface is between the bottom surface of the riparian wetland and the upper surface of the wetlands. The invention achieves good purification and landscape effects. The purification system has some advantages such as good landscape effects, simple management without energy and power consumption, and thus is durable and stable.

Disclosed is a system for managing water. In example embodiments, the system may include a long pond for storing water. In some embodiments the long pond may be used to prevent flooding, in other examples the long pond may be used as a reservoir for holding water usable with irrigation and sub-irrigation systems.

A wave generation system may comprise a submerged platform. The submerged platform may be attached to the bottom of a body of water by cables or pilings. A wave generator may be coupled to the submerged platform. The wave generator may create waves above the submerged platform. The shape of the submerged platform may dictate the shape of the waves. The submerged platform may be adjusted by raising or lowering the submerged platform. The shape of the submerged platform may be adjusted by adjusting the pitch of various sections of the submerged platform. A portion of the energy in the generated waves may be transmitted beyond the submerged platform and dissipated by a surrounding body of water.

A boat lift is attached to piles driven into the earth or to another object. The boat lift is held in horizontal position relative to piles or the object to which it is attached, but vertical movement of the boat lift relative to the object is permitted. The boat lift is connected to the piles by modular units or cube constructs that have a post extending there through. The post has a blade extending from it. The blades are attached at an angle, according to the application, to pile guides that engage piles. The pile guides vertically traverse the piles, permitting the boat lift to move vertically relative to the object, but fixing the horizontal position of the boat lift.

A system and method for restoring wetland habitats and providing a platform on which indigenous and transplanted plant species can thrive. Water from a source, such as, stormwater run-off is captured and filtered through a combination of sand berms and riffle weirs to a series of aquatic beds, thus creating nutrient-rich environment.

The present invention relates to a self filling cover device for covering a surface of a liquid, having a shell (2) defining inner cavity, and the inner cavity is to be filled at least partly with liquid, so that the inner cavity is divided in at least two chambers (3,4) by a separating means (5,51,52), and one of the chambers (4) is provided by at least one opening (6) formed in the shell (2).

The present invention comprises a system for the localized heating of a portion of water within larger water bodies through a partial confinement of said portion of water without completely interrupting the water flow and where the concept of being in the same water body is maintained, in order to facilitate the practice of recreational activities in a heated environment. The present invention provides a solution to achieve a comfortable temperature of the water for direct contact recreational purposes in a cost-efficient manner, with a partial confinement system that allows creating a heat plug and provides for a serpentine-type flow between both sides of the partial confinement system.

Apparatus and associated methods relate to upwelling systems having an array of valvular conduit modules that induce upwelling in a fluid body in response to wave motion. In an illustrative example, each valvular conduit module may be formed as a unitary rigid body extending along a longitudinal axis. The array of valvular conduit modules may be supported, for example, in a substantially vertical orientation by a float module when the system is immersed in the fluid body. The array of valvular conduit modules may be, in some examples, releasably coupled together in a lateral array, a longitudinal array, or some combination thereof. Various embodiments may advantageously passively impart upward flow of the fluid in response to wave-induced vertical displacement.
