A method for controlling the gate based on the habitat requirement for fish overwintering in rivers. According to the characteristics of biological habitat of the river and the habitat demand of fishes during overwintering, the method specifically comprises the steps of: firstly, determining candidate fishes for ecological flow calculation though fish resources investigating and historical data, and then screening out the target fish by adopting hierarchical analysis method; Secondly, establishing a quantitative response relationship curve between target fish physiological adaptions and water temperature, obtaining ecological water level which ensures the target fish overwintering safely according to the vertical temperature distribution, and establishing the relation between water depth and discharge using hydrodynamic model; finally, setting up a gate control system including a radar water level meter in the overwintering areas and an ecological water level management system in a gate control room.

The present de-icing apparatus provides relatively small, portable, and adjustable devices for the specific purpose of de-icing a relatively small area of surface water for use by outdoor enthusiasts. The anchorable stand provides directional, surface height, and angular adjustment of the de-icing water flow to allow for establishing the preferred de-icing pattern at the water surface. De-icing means the reduction of freezing and the minimization of ice accumulation in a given surface area of the open body of water. The fixed-height vertical member of the anchorable stand provides a 360 adjustment range of output water flow. The adjustable-height vertical member of the anchorable stand provides surface height adjustment of the intake and output water flows. The vertical rotation point or points of the anchorable stand hold the water movement device and provide angular adjustment of the intake and output water flow.

Surface modification control stations and methods in a globally distributed array for dynamically adjusting the atmospheric, terrestrial and oceanic properties. The control stations modify the humidity, currents, wind flows and heat removal rate of the surface and facilitate cooling and control of large area of global surface temperatures. This global system is made of arrays of multiple sub-systems that monitor climate and act locally on weather with dynamically generated local forcing & perturbations for guiding in a controlled manner aim at long-term modifications. The machineries are part of a large-scale system consisting of an array of many such machines put across the globe at locations called the control stations. These are then used in a coordinated manner to modify large area weather and the global climate as desired. The energy system installed at a control stations, with multiple machines to change the local parameters of the ocean, these stations are powered using renewable energy (RE) sources including Solar, Ocean Currents, Wind, Waves and Batteries to store energy and provide sufficient power and energy as required and available at all hours. This energy is then used to do directed work using special machines, that can be pumps for seawater to move ocean water either amplifying or changing the currents in various locations and at different depths, in addition it will have machineries for changing the vertical depth profile of the ocean of temperature, salinity and currents. Control stations will also directly use devices such as heat pumps to change the temperatures of local water either at surface or at controlled depths, or modify the humidity and salinity to change the atmospheric and oceanic properties as desired. The system will work in a globally coordinated manner applying artificial intelligence and machine learning algorithms to learn from observations to improve the control characteristics and aim to slow down the rise of global surface temperatures. These systems are used to reduce the temperatures of coral reefs, arctic glaciers and south pacific to control the El Nino oscillations.

A multipurpose blower assembly for stimulating flows in underwater environments, which includes a lower assembly connecting to an upper assembly by a rotating shaft and a mount post for connecting the blower assembly to a supportive structure near a water body and supporting the lower assembly below and the upper assembly above the water body's surface.

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.

This invention uses atmospheric pressure and gravity, only to power a new energy system. Renewable, clean energy from new sources is much needed in the U.S. and the world today. Many possible locations exist in the U.S. that this new system can be installed. If the potential of this new system is fulfilled, the country's economy will benefit greatly over the next many years. Thousands of permanent jobs will be created.

A system for forming an underwater air curtain, that turns the ocean above it into a gas is anchored on the ocean floor, so the curtain's bubbles travel from the ocean floor to the surface. The system is formed by arrays of air distribution tubes carrying air dispersal heads that are powered by an air supply and air batteries. In the shallows, of 30 ft. or less, ocean waves are deleted, oil is repelled, marine animals have a barrier that they cannot enter when the system is activated. Used at deeper depths, the system has the ability to change ocean temperatures, by using bubbles to bring cold water from the ocean floor to the surface thus protecting coral. The system also works as a sound barrier, because the ocean is no longer solid above it.

A system for aeration and separation of contaminants from flowing water in a channel, comprising: a wall (1) partially embedded in the channel of flowing water; a mesh (4) placed above the wall (1); a plurality of baffles (3, 5) partially embedded in the channel and placed opposite to each other in such manner so as to the increase the distance travelled by water; plants algae planted around and on the baffles (3, 5); a flooring (6) sloping towards flowing water direction; a sink (2) constructed at a depth lower than the flooring (6); and a water wheel (11) placed in flowing water.
