Irrigation Wikipedia. The hub of a center pivot irrigation system. Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of inadequate rainfall. Irrigation also has other uses in crop production, including frost protection,1 suppressing weed growth in grain fields2 and preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain fed or dry land farming. Irrigation systems are also used for cooling livestock, dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the removal of surface and sub surface water from a given area. Irrigation has been a central feature of agriculture for over 5,0. Historically, it was the basis for economies and societies across the globe, from Asia to the Southwestern United States. Historyedit. Animal powered irrigation, Upper Egypt, ca. Archaeological investigation has found evidence of irrigation where natural rainfall was insufficient to support crops for rainfed agriculture. Perennial irrigation was practiced in the Mesopotamian plain whereby crops were regularly watered throughout the growing season by coaxing water through a matrix of small channels formed in the field. Ancient Egyptians practiced Basin irrigation using the flooding of the Nile to inundate land plots which had been surrounded by dykes. The flood water was held until the fertile sediment had settled before the surplus was returned to the watercourse. There is evidence of the ancient Egyptian pharaoh. Amenemhet III in the twelfth dynasty about 1. BCE using the natural lake of the Faiyum Oasis as a reservoir to store surpluses of water for use during the dry seasons. The lake swelled annually from flooding of the Nile. The Ancient Nubians developed a form of irrigation by using a waterwheel like device called a sakia. Irrigation began in Nubia some time between the third and second millennium BCE. It largely depended upon the flood waters that would flow through the Nile River and other rivers in what is now the Sudan. In sub Saharan Africa irrigation reached the Niger River region cultures and civilizations by the first or second millennium BCE and was based on wet season flooding and water harvesting. Terrace irrigation is evidenced in pre Columbian America, early Syria, India, and China. In the Zana Valley of the Andes Mountains in Peru, archaeologists found remains of three irrigation canalsradiocarbon dated from the 4th millennium BCE, the 3rd millennium BCE and the 9th century CE. These canals are the earliest record of irrigation in the New World. Traces of a canal possibly dating from the 5th millennium BCE were found under the 4th millennium canal. Sophisticated irrigation and storage systems were developed by the Indus Valley Civilization in present day Pakistan and North India, including the reservoirs at Girnar in 3. BCE and an early canal irrigation system from circa 2. BCE. 1. 21. 3 Large scale agriculture was practiced and an extensive network of canals was used for the purpose of irrigation. Ancient Persia modern day Iran used irrigation as far back as the 6th millennium BCE to grow barley in areas where natural rainfall was insufficient. The Qanats, developed in ancient Persia in about 8. BCE, are among the oldest known irrigation methods still in use today. They are now found in Asia, the Middle East and North Africa. The system comprises a network of vertical wells and gently sloping tunnels driven into the sides of cliffs and steep hills to tap groundwater. The noria, a water wheel with clay pots around the rim powered by the flow of the stream or by animals where the water source was still, was first brought into use at about this time by Roman settlers in North Africa. By 1. 50 BCE the pots were fitted with valves to allow smoother filling as they were forced into the water.

The newest edition of the Civil Engineering Reference Manual has been updated to the latest NCEES exam adopted codes. Hydrology deals with the occurrence, movement, and storage of water in the earth system. Hydrologic science comprises understanding the underlying physical and. The irrigation works of ancient Sri Lanka, the earliest dating from about 3. BCE, in the reign of King Pandukabhaya and under continuous development for the next thousand years, were one of the most complex irrigation systems of the ancient world. In addition to underground canals, the Sinhalese were the first to build completely artificial reservoirs to store water. Due to their engineering superiority in this sector, they were often called masters of irrigation. Most of these irrigation systems still exist undamaged up to now, in Anuradhapura and Polonnaruwa, because of the advanced and precise engineering. The system was extensively restored and further extended during the reign of King Parakrama Bahu 1. Enterprise Rent A Car Management Program'>Enterprise Rent A Car Management Program. CE. 1. 7The oldest known hydraulic engineers of China were Sunshu Ao 6th century BCE of the Spring and Autumn period and Ximen Bao 5th century BCE of the Warring States period, both of whom worked on large irrigation projects. In the Sichuan region belonging to the State of Qin of ancient China, the Dujiangyan Irrigation System devised by the Qin Chinese hydrologist and irrigation engineer Li Bing was built in 2. BCE to irrigate a vast area of farmland that today still supplies water. By the 2nd century AD, during the Han Dynasty, the Chinese also used chain pumps that lifted water from lower elevation to higher elevation. These were powered by manual foot pedal, hydraulic waterwheels, or rotating mechanical wheels pulled by oxen. The water was used for public works of providing water for urban residential quarters and palace gardens, but mostly for irrigation of farmland canals and channels in the fields. In 1. 5th century Korea, the worlds first rain gauge, uryanggye Korean, was invented in 1. The inventor was Jang Yeong sil, a Korean engineer of the Joseon Dynasty, under the active direction of the king, Sejong the Great. It was installed in irrigation tanks as part of a nationwide system to measure and collect rainfall for agricultural applications. With this instrument, planners and farmers could make better use of the information gathered in the survey. Email markrainsun atgmail dotcom Here are some listed. PDFA Brief Introduction To Fluid Mechanics, 5th Edition INSTRUCTOR SOLUTIONS MANUAL. North Americaedit. Irrigation ditch in Montour County, Pennsylvania. The earliest agricultural irrigation canal system known in the U. S. dates to between 1. B. C. and 8. 00 B. C. and was discovered in Marana, Arizona adjacent to Tucson in 2. The irrigation canal system predates the Hohokam culture by two thousand years and belongs to an unidentified culture. In North America, the Hohokam were the only culture known to rely on irrigation canals to water their crops, and their irrigation systems supported the largest population in the Southwest by AD 1. The Hohokam constructed an assortment of simple canals combined with weirs in their various agricultural pursuits. Between the 7th and 1. Mirc S Older Version more.

These were constructed using relatively simple excavation tools, without the benefit of advanced engineering technologies, and achieved drops of a few feet per mile, balancing erosion and siltation. Economics Graphing Software more. The Hohokam cultivated varieties of cotton, tobacco, maize, beans and squash, as well as harvested an assortment of wild plants. Late in the Hohokam Chronological Sequence, they also used extensive dry farming systems, primarily to grow agave for food and fiber.
