A method of designing an optimized seawater pumping apparatus, using a computer in a system in which a seawater pumping apparatus including a pumping pipe and a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe is installed to reduce seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed, includes applying an optimization algorithm to initial condition data of the aquifer to generate n decision variable sets of the seawater pumping apparatus, applying an underground water flow model to each of the n decision variable sets to generate n prediction results of change in the seawater-fresh water boundary surface, calculating a performance evaluation value of each of the n prediction results, and selecting a decision variable set having a maximum performance evaluation value, where n is an integer and equal to or greater than 2.

Systems and related methods for purging air burst supply piping of accumulated water prior to delivering pulses of pressurized air to an interior of a screen intake through the air burst supply piping. The systems and methods can include a purge compressor delivering a purging air supply at a head pressure slightly above a head pressure of water in the air burst supply piping, wherein the head pressure of the water is equivalent to a depth at which the intake screen. The system and methods can also include a purge line arranged in a parallel orientation to an air burst supply line, wherein both the purge line and the air burst supply line are operably coupled to a pressurized air tank.

Offshore apparatus generating artificial Taylor columns for the purpose on interfering with oncoming storm surge and/or tsunamis. A series of solid bodies are anchored relative to the ocean floor to provide structures capable of generating Taylor columns in response to water flow and/or currents. The strategic placement of a series of cylindrical bodies creates a corresponding series of Taylor columns in response to hydrodynamic flow, such as current flow or tsunami related flow. The presence of a series of strategically located Taylor columns is intended to inhibit or disrupt the devastating effects of storm surge and/or tsunamis.

Disclosed is a non-powered seawater pumping apparatus for reducing seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed, the apparatus including a pumping pipe having opposite open end portions, a first end portion of the opposite open end portions being positioned below a sea level and a second end portion being positioned below a seawater-fresh water boundary surface in the land, and a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe, which is buried in the land, so as to space away the land-buried portion of the pipe from the land, wherein seawater is filled in the pumping pipe, and the well includes a screen having a plurality of through holes formed along a circumference of the well at a lower end portion of the well.

A weather mitigation assembly for reducing the surface temperature of the ocean to mitigate developing oceanic weather systems includes a buoy that is floated on the ocean. An air pump is coupled to the buoy and a plurality of tethers is each coupled between the buoy and the ocean floor for keeping the buoy in a selected spot. A network of bubble pipes is each laid along the ocean floor. A supply pipe is fluidly coupled between the air pump and the network of bubble pipes. In this way the air pump can pump air into the network of bubble pipes. Each of the bubble pipes releases air bubbles upwardly toward the surface of the ocean urge cool water on the ocean floor upwardly toward the surface of the ocean. In this way the surface of the ocean can be cooled thereby reducing thermal energy available for developing weather systems.

The invention discloses a reservoir tail reverse regulation method for native fish protection, comprising the steps that firstly, a breeding habitat of native fishes at reservoir tail of a cascade hydroelectric dam is determined; secondly, breeding characteristics of migration native fishes are determined, and an ecological conservation project of a reach of the breeding habitat at reservoir tail is carried out; thirdly, the length of the reservoir tail of a downstream hydropower station of a cascade hydroelectric project in March to May is determined through a field investigation, and the maximum range of a natural river channel downstream of the upstream cascade power station is judged and finally, the flow state of the reach at reservoir tail is reversely regulated to achieve the goal of discharging water of the natural river channel at the reservoir tail and ensuring the natural flow state of the natural river channel.
