English: A new, major development in carrier fire prevention occurred on 26 May 1969 when the U.S. Navy aircraft carrier USS Franklin D. Roosevelt (CVA-42) put to sea from the Norfolk Naval Shipyard, Portsmouth, Virginia (USA), after an 11-month overhaul which included installation of a deck edge spray system using a new seawater compatible fire-fighting chemical, Light Water.
The WFD requires member states to implement monitoring systems to estimate the integrity of biological stream components for specific sub-surface water categories. This requirement increased the incidence of biometrics applied to ascertain stream health in Europe [ 13 ] A remote online biomonitoring system was designed in 2006.
The MOSE system is flexible: depending on the winds, atmospheric pressure and level of tide, it can oppose the high water in different ways – with simultaneous closure of all three inlets in the case of exceptional tides, by closing just one inlet at a time, or by partially closing each inlet—given that the gates are independent—for ...
Water rising above a canal's full capacity may cause flooding to spread to other waterways and areas of the community, which causes damage. Defenses (both long-term and short-term) can be constructed to minimize damage, which involves raising the edge of the water with levees, embankments or walls. The high population and value of ...
The fish are then returned to the water unharmed. The water environment on Earth includes the seas and oceans, the rivers lakes, marshes, streams and the fozen waters in ice-caps and glaciers. Because of the importance of water to life, monitoring of water wherever it occurs is critical to the environmental well-being of the earth biome. [29]
A restoration plan began in 1999 with the goals of reestablishing ecological integrity of the river-floodplain system. [20] The project involves dechannelizing major sections of the river, directing water into reconstructed channels, removing water control structures, and changing flow regimes to restore seasonal flooding to the floodplain.

Dolphin WaterCare is a brand of environmentally responsible pulsed-power water treatment technology patented by Clearwater Systems Corporation. [3] [4] The system is designed to control scale, corrosion and biological activity in cooling towers without the use of chemicals, chemical tanks or pumps. [5]
Environmental technology (envirotech) is the use of engineering and technological approaches to understand and address issues that affect the environment with the aim of fostering environmental improvement. It involves the application of science and technology in the process of addressing environmental challenges through environmental ...
