1.Introduction, importance of water in the economy of Oman. Oman is located in the arid belt and has an average rainfall of around 100 millimeters per year and the situation has led to Oman's economy relying on groundwater and rainwater to meet growing water needs, projects have been implemented inventory and wells falaj, the creation of a modern network to monitor water conditionsWater resources in the Sultanate: Falaj: the model for the practical man of genius and ability to deal with the environment and take advantage of it and the quality of source water and periods of water flowWells: a vital and reliable source of life and has provided wells and falaj for inventory projects. Springs: A major source of water wealth in Amman, depending on the quality of the affected water like other water sources in terms of the amount of annual rainfall. Underground basins: represent the underground basins of the most important water sources in the Sultanate. Water needs for the availability of safe drinking water. I will talk about it in this assignment about one of the sources of water resources in the Sultanate is Falaj. Importance of water for the economy of Oman. almost all sectors, from agriculture to water, represent many industrial activities in the economic development of the country. Water is one of many important goods and services. For example, most of the energy production process requires a lot of water, which is used for extraction, for cooling, for thermal energy production, for oil processing and for hydroelectric power production. The importance of farmers' water supply for agricultural production and fishing industryWater is of economic importance so that the availability of water associated with the creation of civilizations, cities and the important...... means of paper......according to its source, length, depth, flow and continuityFalaj al - Daoudi: their origin from the depths of the earth up to 40 meters deep and 12 kilometers long and are not exposed to droughtFalaj Agheila: their continuous surface water source such as valleys emitted by rain and heavy rain hit quickly with a length of less than 5 kilometers. Falaj type: from springs and cold and hot eyes and be drinkable. Oman maintains cultural heritage and still maintains it by building wells, helps and does inventory of Falaj wells and periodic maintenance every 3 months and international fairs work to inform the world about the importance of Aflaj and intelligent man of Oman. Finally, let's keep Aflaj and think about how to keep modern engineering tools to be ongoing in the coming years. Works Cited www .wiki.com
