Dirty Devil River
The Dirty Devil River is an tributary of the Colorado River, located in the U.S. state of Utah. It flows through southern Utah from the confluence of the Fremont River and Muddy Creek before emptying into the Colorado River at Lake Powell. Course The Dirty Devil River is formed in Wayne County near Hanksville at the confluence of the Fremont River and Muddy Creek. It flows generally southward through a canyon in Wayne and Garfield counties. Its lower flows through Glen Canyon National Recreation Area, where it finally disembogues into the Colorado River at a point that is now submerged beneath Lake Powell. The canyon carved by the river is particularly isolated and seldom visited compared to other natural areas in the region. The average discharge is approximately 446 cubic feet per second. History The Dirty Devil River was named by the 1869 Powell Geographic Expedition led by John Wesley Powell, which explored much of the Colorado River and its tributaries. It was nam ...

Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington DC, and with oversight over , it governs one eighth of the country's landmass. President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The agency manages the federal government's nearly of subsurface mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. The mission of the BLM is "to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations." Originally BLM holdings were described as "land nobody wanted" because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Wayne County, Utah
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, spring ...

Tributaries Of The Colorado River In Utah
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & Scott ...

State Route 95 (Utah)
State Route 95 or Bicentennial Highway is a state highway located in the southeast of the U.S. state of Utah. The highway is an access road for tourism in the Lake Powell and Cedar Mesa areas, notably bisecting Bears Ears National Monument and providing the only access to Natural Bridges National Monument. The highway does not serve any cities, but the small town of Hanksville is its western terminus. Although the highway has existed since the 1930s as a primitive dirt road, it received its name at its dedication as a paved state highway coincident with the U.S. Bicentennial in 1976. The highway forms part of the Trail of the Ancients National Scenic Byway. Route description It runs west from the junction of U.S. Route 191 (4.3 miles south of the town of Blanding), to the junction of SR-24 in the town of Hanksville. It crosses Cottonwood Wash just west of the US-191 junction; follows and crosses White Canyon; and crosses the Colorado River and the northeast end of Lake Po ...

Hite Crossing Bridge
The Hite Crossing Bridge is an arch bridge that carries Utah State Route 95 across the Colorado River northwest of Blanding, Utah, United States. The bridge informally marks the upstream limit of Lake Powell and the end of Cataract Canyon of the Colorado River, but when the lake is at normal water elevation, the water can back up over upstream into Cataract Canyon. The bridge is the only automobile bridge spanning the Colorado River between the Glen Canyon Bridge, downstream near the Glen Canyon Dam and the U.S. Route 191 bridge upstream near Moab. The bridge is near Hite Marina on Lake Powell, and a small airstrip is immediately adjacent to the north side of the bridge. History The Colorado River served as a major barrier to early settlers and explorers of the region. In 1880 a prospector named Cass Hite established a ford near the mouth of the Dirty Devil River, downstream from the present-day bridge location. This ford, named "Dandy Crossing", served as one of the few l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cost-effectiveness Analysis
Cost-effectiveness analysis (CEA) is a form of economic analysis that compares the relative costs and outcomes (effects) of different courses of action. Cost-effectiveness analysis is distinct from cost–benefit analysis, which assigns a monetary value to the measure of effect. Cost-effectiveness analysis is often used in the field of health services, where it may be inappropriate to monetize health effect. Typically the CEA is expressed in terms of a ratio where the denominator is a gain in health from a measure (years of life, premature births averted, sight-years gained) and the numerator is the cost associated with the health gain. The most commonly used outcome measure is quality-adjusted life years (QALY). Cost–utility analysis is similar to cost-effectiveness analysis. Cost-effectiveness analyses are often visualized on a plane consisting of four quadrants, the cost represented on one axis and the effectiveness on the other axis. Cost-effectiveness analysis focuses on m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marginal Cost
In economics, the marginal cost is the change in the total cost that arises when the quantity produced is incremented, the cost of producing additional quantity. In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount. As Figure 1 shows, the marginal cost is measured in dollars per unit, whereas total cost is in dollars, and the marginal cost is the slope of the total cost, the rate at which it increases with output. Marginal cost is different from average cost, which is the total cost divided by the number of units produced. At each level of production and time period being considered, marginal cost includes all costs that vary with the level of production, whereas costs that do not vary with production are fixed. For example, the marginal cost of producing an automobile will include the costs of labor and parts needed for the additional automobile but not th ...

United States Bureau Of Reclamation
The Bureau of Reclamation, and formerly the United States Reclamation Service, is a federal agency under the U.S. Department of the Interior, which oversees water resource management, specifically as it applies to the oversight and operation of the diversion, delivery, and storage projects that it has built throughout the western United States for irrigation, water supply, and attendant hydroelectric power generation. Currently the Bureau of Reclamation is the largest wholesaler of water in the country, bringing water to more than 31 million people, and providing one in five Western farmers with irrigation water for 10 million acres of farmland, which produce 60% of the nation's vegetables and 25% of its fruits and nuts. The Bureau of Reclamation is also the second largest producer of hydroelectric power in the western United States. On June 17, 1902, in accordance with the Reclamation Act, Secretary of the Interior Ethan Allen Hitchcock established the U.S. Reclamatio ...
