Abstract:
The invention provides a marine infrastructure comprising a concrete matrix having a pH of less than 12 for use in promoting the growth of fauna and flora in aquatic environment, and methods for promoting the growth of fauna and flora in aquatic environment, including endolitic and epilitic flora and endolitic and epilitic anaerobic and aerobic flora and fauna.
Abstract:
A method of restoring a lake that has a high saline level is disclosed herein. In order to restore the lake, a series of concentric dikes or levees are provided that separate the lake into a plurality of smaller lake sections, each having a water surface. The smaller lake sections include an outer lake section which is next to the periphery of the lake and one or more inner lake sections. Each dike and each smaller lake section water surface have an elevation. Water is flowed from an influent source to the outer lake section and then to each of the inner lake sections. The outer lake section surface has a higher elevation. The inner lake section surfaces have cascading lower surface elevations. At a central area, a breathing brine area is provided that is surrounded by the smaller lake sections to provide an area that can be used to concentrate brine. The smaller lake sections can have differing salinity levels for sustaining diverse marine and plant life.
Abstract:
According to an embodiment, there is provided a method for mitigating seawater intrusion in the ground where an aquifer having a seawater-fresh water interface is formed, the method including: installing an injection well at a point on an inland area, spaced apart from the sea by a predetermined distance, to a predetermined injection depth (d), the injection well having a predetermined screen height; injecting seawater into the aquifer by a predetermined quantity of injection through the injection well; and forming an upper seawater area around the injection well by the injection of the seawater, wherein the upper seawater area is an area that is filled with seawater in an upper portion of the aquifer.
Abstract:
Disclosed herein is a device for tracking the position of a freshwater-saltwater interface of underground water in the coastal area. The device includes a buoyancy adjustment unit which comprises a pipe that has an internal space and is closed on a lower end thereof, a sealing cap which is removably coupled to an upper end of the buoyancy adjustment unit, a variable metal member which is attached to the sealing cap, a cordless measurement sensor which is provided under the lower end of the buoyancy adjustment unit, and a perforated pipe which is coupled to the lower end of the buoyancy adjustment unit and covers the cordless measurement sensor. Distilled water is supplied into the buoyancy adjustment unit, and a buoyancy of the buoyancy adjustment unit is adjusted depending on the amount of distilled water.
Abstract:
A method and a plant for storing freshwater to distribute it as consumption water are disclosed. The freshwater is enclosed within a downwardly open tank floating in a body of salt water, e.g. seawater and defined laterally by suspended, substantially vertical curtains and at its top end at least partly by a floating cover. The freshwater is supplied to the tank adjacent its top end so as to form an upper freshwater body therein, the lower portion of the tank being taken up by the salt water. A distinct horizontal boundary layer is formed between the freshwater and the salt water bodies and will move up and down in response to supply and withdrawal of the freshwater. To restrict diffusion of salt water into the freshwater body a separating layer of material having a density intermediate those of the freshwater and the salt water may be arranged at the boundary layer.
Abstract:
A hot water reservoir comprises buoys floating on the surface of a lake, and a flexible wall fastened to said buoys hanging down into the water. Weights are fastened to the lower edge of said wall. Cables extend from the buoys to the weights so as to reinforce said flexible wall. The buoys are fastened to anchoring wires extending toward the interior of the reservoir.
Abstract:
A controlled containment barrier system is provided that can prevent the migration of dissolved phased contaminants in water systems. The system includes sheet piling installed in a body of water, the sheet piling having valves disposed at various vertical elevations on the sheet piling panels that allow the discharge of water at various strata in the body of water through the barrier system.
Abstract:
A system of floating canal sections that connect end-to-end along a route to form a shipping canal and contain brine to prevent freezing. The canal sections of the present invention resemble floating dry-docks that are filled with the brine solution rather than with normal sea water. Sections can be floated into place and connected. Sections can be anchored to the sea floor. A typical section can be around 1000 feet long, 150 feet wide and about 50 feet deep. The sections can be manufactured anywhere and towed to the Arctic and connected. The use of brine prevents pollution if there should be a leak.
