Rhythmic Spring
A rhythmic spring (also: ebb and flow spring, periodic spring, intermittent spring) is a cold water spring from which the flow of water either varies or starts and stops entirely, over a fairly regular time-scale of minutes or hours. Compared to continuously-flowing springs, rhythmic springs are uncommon, with the number worldwide estimated in 1991 to be around one hundred. Theory Although the cause of the periodicity in flow is not known for certain, the most accepted theory (first postulated in the early 18th century) is that as groundwater flows continuously into a cavern, it fills a narrow tube that leads upwards from near the base of the cavern, then downwards to the spring. As the water level reaches the high point of the tube, it creates a siphon effect, sucking water out of the chamber. Eventually air rushes into the tube and breaks the siphon, stopping the flow if there is no other source feeding the spring, or reducing the flow if there is a continuous flow from another ...

Spring (hydrosphere)
A spring is a point of exit at which groundwater from an aquifer flows out on top of Earth's crust (pedosphere) and becomes surface water. It is a component of the hydrosphere. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. Their yield varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the groundwater table reaches above the surface level. Springs may also be formed as a result of karst topography, aquifers, or volcanic activity. Springs also have been observed on the ocean floor, spewing hot water directly into the ocean. Springs formed as a result of karst topography create karst springs, in which ground water travels throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Utah
The University of Utah (U of U, UofU, or simply The U) is a public research university in Salt Lake City, Utah. It is the flagship institution of the Utah System of Higher Education. The university was established in 1850 as the University of Deseret () by the General Assembly of the provisional State of Deseret, making it Utah's oldest institution of higher education.

Intermittent Spring (Wyoming)
Intermittent Spring, also called Periodic Spring, is located in Swift Creek canyon in Star Valley, near Afton, Wyoming. It is the largest rhythmic spring in the world. The great great grandfather of Rulon Gardner is credited with the discovery. Gardner says, "He was up there logging. He went up and found a nice little place to get some fresh water. It was intermittent. It went, and stopped. So it was pretty amazing". Siphon theory The theory is that as groundwater flows continuously into a cavern, it fills a narrow tube that leads out. As it pours over the high point of the tube, it creates a siphon effect, sucking water out of the chamber. Eventually air rushes in and breaks the siphon. Kip Solomon, a hydrologist at the University of Utah, said, "We can't think of another explanation at the moment". When the University of Utah conducted and finished their studies, Solomon concluded that "The spring water's gas content has now been tested at the University of Utah. The data str ...

Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star Valley
Star Valley is located in the United States between the Salt River Range in western Wyoming and the Webster Range of eastern Idaho. The altitude of the valley ranges from to . Three major Wyoming rivers, the Salt River, the Greys River and the Snake River meet near Alpine Junction at Palisades Reservoir. Numerous towns are located in the valley, including Afton, Thayne, Bedford, Etna, Smoot, Fairview, Osmond, Freedom, Grover, Auburn, Alpine, Nordic, Turnerville and Star Valley Ranch. Star Valley was settled in the late 1870s by Mormon pioneers. Primary sources indicate Star Valley was proclaimed the "Star of All Valleys" for its natural beauty by a general authority of the Church of Jesus Christ of Latter-day Saints (LDS Church). The name was later shortened to Star Valley. Another less supported theory about the origin of the name comes from Starvation (Starve) Valley, a name the area gained during bitter winters in the late 1880s. History Star Valley was ...

Hydrology
Hydrology () is the scientific study of the movement, distribution, and management of water on Earth and other planets, including the water cycle, water resources, and environmental watershed sustainability. A practitioner of hydrology is called a hydrologist. Hydrologists are scientists studying earth or environmental science, civil or environmental engineering, and physical geography. Using various analytical methods and scientific techniques, they collect and analyze data to help solve water related problems such as environmental preservation, natural disasters, and water management. Hydrology subdivides into surface water hydrology, groundwater hydrology (hydrogeology), and marine hydrology. Domains of hydrology include hydrometeorology, surface hydrology, hydrogeology, drainage-basin management, and water quality, where water plays the central role. Oceanography and meteorology are not included because water is only one of many important aspects within those fields. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gihon Spring
Gihon Spring () or Fountain of the Virgin, also known as Saint Mary's Pool, A.H. Sayce, "The Inscription at the Pool of Siloam," ''Palestine Exploration Fund Quarterly Statement'' 13.2 (April 1881): ( editio princeps), p72/ref> is a spring in the Kidron Valley. It was the main source of water for the Pool of Siloam in Jebus and the later City of David, the original site of Jerusalem. One of the world's major intermittent springs – and a reliable water source that made human settlement possible in ancient Jerusalem – the spring was not only used for drinking water, but also initially for irrigation of gardens in the adjacent Kidron Valley, which provided a food source for the ancient settlement. The spring rises in a cave 20 feet by 7, and is located 586 yards (535 m) northwards of the Pool of Siloam. Being intermittent, it required the excavation of the Pool of Siloam, which stored the large amount of water needed for the town when the spring was not flowing. Befo ...

City Of David (historic)
The City of David ( he, עיר דוד, translit=Īr Davīd) is the name given to an archaeological site considered by most scholars to be the original settlement core of Jerusalem during the Bronze and Iron Ages. "The prevailing view among researchers that the early city, the City of David, lay in the southern part of the eastern ridge next to the spring." It is situated on southern part of the eastern ridge of ancient Jerusalem, west of the Kidron Valley and east of the Tyropoeon valley, to the immediate south of the Temple Mount. The City of David is an important site of biblical archeology. Remains of a defensive network dating back to the Middle Bronze Age were found around the Gihon Spring; they continued to remain in use throughout subsequent periods. Two monumental Iron Age structures, known as the Large Stone Structure and the Stepped Stone Structure, were discovered at the site. Scholars debate if these may be identified with David or date to a later period. The site i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
