1.Introduction, importance of water to Oman economy.
Oman is located in the arid belt and an average rainfall of about 100 millimeters per year and the situation has led to reliance on groundwater and rainwater to meet the growing needs of the water projects were implemented falaj inventory and wells , the establishment of a modern network to monitor water conditions
Water resources in the Sultanate:
Falaj : The model for the practical man of genius and ability to deal with the environment and take advantage of them and the quality of the source water and the water flow periods
Wells : a source of vital important for life and reliable and has provided inventory project wells and falaj .
Springs : one main water sources of wealth in

The most dangerous part of the job - in the rocky soil to break the back - the source of the water near the worker, or rain water or soil , and at this point, and a constant flow of water in a narrow channel , usually less than a meter a broad range of (3 feet ) , but not much higher
Some irrigation canals with the springs should be cleaned about once every 30 years , and sometimes, when the water level drops due to groundwater depletion , Falaj been abandoned , or deepen wells. Because it is expensive , and the cost , usually , and the sharing of the entire community.

Each year, at least 7.8 trillion gallons of water are drawn up from the Ogalla Aquifer to irrigate the crops planted on the High Plains. These cros are the main food sourrce for our entire country. Tragically, irrigation is depleting the aquifer faster than it can replenish itself, and that is the problem. In fact, only the tiniest fraction of the water is ever replaced in the Ogallala Aquifer. If the water were ever fully depleted, the aquifer would need 6,000 years to refill naturally (Zwingle 83). The only way the Ogalla can be replenished is by water seeping down through the layers of soil until it reaches the aquifer. This water comes from the small amount of precipitation in the region, as well as from streams, reservoirs, canals, and irrigation (McGuire and Sharpe).
The study is intended to contribute to the national capacity building for water management. From the foregoing it can be seen that the study is important since it will contribute to the determination of ways of how water could be managed on a sustainable and efficient basis without incurring great negative externalities to the resource as well as to the environment.
As we all understand, the Earth has many landmarks and it is these physical features that create an abundant and organized system within which we thrive. One of the most abundant natural resources on the planet is water and the importance of this element is as crucial as any other. For the fortunate few who get to utilize it, this amazing reserve provides us with our necessity for daily consumption as well as our ability to grow just about anything we please. Common irrigation practices are essential for gathering water into a contained area to grow crops that would not typically survive in areas without heavy rainfall. As a matter of fact, “irrigation is an ancient practice that originated along the Tigris and Euphrates Rivers in what is now Iraq” and is now the result of an estimated 40 percent of all crops grown around the world (Water Encyclopedia). This tactic has provided many different cultures with numerous varieties of crops as well as growth in crop yield which in turn dramatically advances human civilization. As we develop into a more progressive society, the tools and systems used to grow our crops also become more intelligent as well as sustainable
Water, like food, is a necessity for human life that is used for many purposes such as agricultural, industrial, and domestic systems. While water is a common element around the world not all of it is clean and able to be consumed or used by humans. With only a percentage of the world’s water being clean and the use of water increasing, the availability of water around the world has become a common issue in the developing and even the developed world. This may be a smaller problem in areas close to clean water sources compared to areas far from a clean water source but, the availability of water is not strictly based on location, it also depends on the specific political and social needs and issues of the area as well. These all become issues that must be accounted for when deciphering whether water is a basic human right or a commodity and what action must be taken to aid the developing water systems in community’s that lack them.
The current water shortage has left many reservoirs depleted with water. Littlerock reservoir has had a decrease in its water level in the recent years. The loss in water has had a devastating toll on the agriculture
Central idea: Access and availability to fresh water are essential to the survival of the human race. Fresh
supply for the operation is a major challenge. Olympic Dam and the township of Roxby Downs currently use water that
Water is an essential part of life. While most people are fortunate enough to have stable access to it, others are not blessed with it and have to use unsanitary and other unhealthy alternatives. Areas such as India and even in the United States in Flint, Michigan suffer from a bad water supply to this day, the modern era.
According to WSDP (2002) in 2001 urban water coverage of Ethiopia is 74.4%, and population served reaches 9,886,000.The water coverage ranges from 25% in Harar to 96% in Amhara region. However there are discrepancies among different documents regarding urban water coverage. For instance WSDP (2002) in Assefa (2006) indicated the urban water coverage of
Egypt faces a water crisis because the Nile river disappearing and it is how they farm and get water.“Egypt gets almost all of its water from the Nile. The quality of the river water is seriously threatened by untreated industrial and agricultural wastes, sewage, and municipal waste-water. In addition, the Aswan High Dam, which was completed in 1970, has reduced the flow of the Nile and trapped the nutrient in the soil,which is not good So if Egypt doesn't get some help from the other countries it will eventually cease to have life
Water is not a free good. In fact, it’s expensive. These conditions lead to awareness of water management challenges.
Water is found everywhere on earth : from ice-covered lakes to tropical rains, yje surface of our planet is covered with almost three quarters of water. However, water is still one of the most precious resource for humanity : only 2.5% of water is pure. Water is therefore a renewable but no unlimited natural resource which is at the center of many debates : considered as the most sever threat in the world, water shortage crisis is spreading in the news. This essay will discuss the following : first, we will see how water is linked to everything; ten we will see that water crisis has a lot of repercussions on developing countries and their growth. Finally we will discuss
It is apparent from the lines chart, precisely in agriculture, the water consumption was always higher than others, although the consumption in threes areas had increase and reached at peak in 2000. The water used for agriculture was about 500km in 1000, during one hundred years after, it climbed significantly to 3000km, which was largest number in 2000. This figure had just over three times as much as the highest proportion in industrial use and six times as much as its of domestic use. Moreover, both water consumption of industries and homes bottomed out in 1900 at below 100km.
Preserving fresh water has become the essential thing now days, due to a metropolitan growth of
Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard. This region is thought to be one of the droughtiest places in the world, most of it’s territory is deserted. Freshwater accounts to 1 percent of the world’s supplies, while the population comes
