Quinault Canyon
The Quinault Canyon is a submarine canyon, off Washington state, in Olympic Coast National Marine Sanctuary. The area It lies opposite the Quinault Reservation. From the map, it is clear the Quinault River drains into the Pacific Ocean, opposite Quinault Canyon. The north of the Copalis National Wildlife Refuge is also a bit east, as are a few cities and sites, as Kalaloch, Queets, Taholah, Point Grenville (a headland), Moclips, and Pacific Beach. Also, Quinault, Washington and Lake Quinault are both onshore. The canyon is dynamic area where humans do not detect massive submarine landslides which occur on its steep side walls, and the bottom collects sediment deposited from above. Its dimensions Quinault Canyon is from shore, and is 378 square nautical miles in area.

Nautical Miles
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrodynamics
In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases. It has several subdisciplines, including ''aerodynamics'' (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves the calculation of various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.

1980 Eruption Of Mount Saint Helens
On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 AM. The eruption, which had a Volcanic Explosivity Index of 5, was the most significant to occur in the contiguous United States since the much smaller 1915 eruption of Lassen Peak in California. It has often been declared the most disastrous volcanic eruption in U.S. history. The eruption was preceded by a two-month series of earthquakes and steam-venting episodes caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain's north slope. An earthquake at 8:32:11 am PDT ( UTC−7) on Sunday, May 18, 1980, caused the entire weakened north face to slide away, a sector collapse which was the largest subaerial landslide in r ...

Guide Canyon
A guide is a person who leads travelers, sportspeople, or tourists through unknown or unfamiliar locations. The term can also be applied to a person who leads others to more abstract goals such as knowledge or wisdom. Travel and recreation Explorers in the past venturing into territory unknown by their own people invariably hired guides. Military explorers Lewis and Clark were hired by the United States Congress to explore the Pacific Northwest. They in turn hired the better qualified Native American Sacagawea to help them. Wilfred Thesiger hired guides in the deserts that he ventured into, such as Kuri on his journey to the Tibesti Mountains in 1938. Tour guide Tour guides lead visitors through tourist attractions and give information about the attractions' natural and cultural significance. Often, they also act as interpreters for travelers who do not speak the local language. Automated systems like audio tours are sometimes substituted for human tour guides. Tour operato ...
