The first successful efforts to control the flow of water were made in Mesopotamia‚ Egypt and Levant. These lands were home to the earliest civilizations that thrived because of the water management practices they used. The Nile River played an important role in the lives of Egyptians‚ they practiced a form of water management called basin irrigation‚ a productive use of the natural rise and fall of the river. Egyptian farmers did not experience the problems that plagued other irrigation societies

WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen

Using named examples‚ assess the contribution of large scale water management projects in increasing water security. 15 Water security means having access to sufficient‚ safe‚ clean and affordable water. Theoretically‚ the world’s poorer countries are the most water insecure‚ suffering from both physical and economic water scarcity. One solution to tackle water insecurity is through large scale water projects for example the Three Gorges project in China‚ the South-North transfer project also in

Introduction Water pollution is the contamination of water by foreign substances such as chemicals‚ pesticides‚ animal wastes‚ sewage‚ disease‚ and organic matter. There are two primary sources of water pollution‚ point source and non-point source pollution. Point source pollution originates from specific locations‚ and can bet traced to specific pipes or ditches and is generally waste or effluent from industry or sewage treatment.

Water use and misuse OUR pot of water woes is brimming over. That does not seem surprising‚ according to Ramaswamy R. Iyer‚ since even though India is one of the few countries in the world which is blessed with an adequate quantity of water‚ there is a tremendous amount of mismanagement of water resources. While the country has over 4‚000 billion cubic meters (bcm) of annual rainfall and almost 2000 bcm of river flow‚ the reality remains that we have had constant lamentations about the shortage

Water: the source of life Water is an indefinable element. It can be destructible and wipe out the strongest forces in the world while it was also the beginning of life. It gives a lot but it can take back more than that. Water is one of the four elements of nature. It’s represented in the liquid form while earth is sold‚ air is gas and fire is the in-between of all. Water is important to every living thing. For plants it’s absorbed from the soil‚ for humans it’s for drinking and use for various

Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity
