Creek (tidal)

A tidal creek, tidal channel, or estuary is the portion of a stream that is affected by ebb and flow of ocean tides, in the case that the subject stream discharges to an ocean, sea or strait. Thus this portion of the stream has variable salinity and electrical conductivity over the tidal cycle. Due to the temporal variability of water quality parameters within the tidally influenced zone, there are unique biota associated with tidal creeks, which biota are often specialised to such zones.

Creeks may often dry to a muddy channel with little or no flow at low tide, but often with significant depth of water at high tide.

Names

In British English and in many other countries in the Commonwealth, as well as some parts of the United States (near the Chesapeake Bay, parts of New England), a creek is a tidal water channel. In the tidal section of the River Thames in London, the names of the rivers that flow into it all become Creeks for the lower section that is tidal; thus, for example the River Lea becomes Bow Creek in its tidal section. In parts of southwest England and Wales, the term 'pill' is used, and is found in placenames such as Huntspill.

Tide

Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth.

The times and amplitude of tides at a locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing). Some shorelines experience a semi-diurnal tide - two nearly equal high and low tides each day. Other locations experience a diurnal tide - only one high and low tide each day. A "mixed tide"; two uneven tides a day, or one high and one low, is also possible.

Tides vary on timescales ranging from hours to years due to a number of factors. To make accurate records, tide gauges at fixed stations measure the water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called mean sea level.

Tidal (livecoding)

Tidal is a live coding environment designed for musical improvisation. In particular, it is a domain-specific language embedded in Haskell, focused on the generation and manipulation of audible or visual patterns. It was originally designed for heavily percussive, polyrhythmic grid-based music, but now uses a flexible, functional reactive representation for patterns, using rational time. Tidal may therefore be applied to a wide range of musical styles, although its cyclic approach to time means that it affords use in repetitive styles such as Algorave.

In its native configuration, Tidal triggers samples on disk via a C-language sampler called Dirt . However there also exist integrations for MIDI, and for the SuperCollider sound environment.

Muscogee

The Muscogee (or Muskogee), also known as the Creek, are a Native American people traditionally from the southeastern woodlands.Mvskoke is their name in traditional spelling. Today Muscogee people live primarily in Oklahoma, Alabama, Georgia, and Florida. Their language, Muscogee, is a member of the Muscogee branch of the Muscogean language family.

The Muscogee are descendants of the Mississippian culture peoples, who built earthwork mounds at their regional chiefdoms located throughout the Mississippi River valley and its tributaries. The historian Walter L. Williams and others believe the early Spanish explorers encountered ancestors of the Muscogee when they visited Mississippian-culture chiefdoms in the Southeast in the mid-16th century.

The Muscogee were the first Native Americans considered to be "civilized" under George Washington's civilization plan. In the 19th century, the Muscogee were known as one of the "Five Civilized Tribes", because they had integrated numerous cultural and technological practices of their more recent European American neighbors. Influenced by their prophetic interpretations of the 1811 comet and earthquake, the Upper Towns of the Muscogee, supported by the Shawnee leader Tecumseh, began to resist European-American encroachment. Internal divisions with the Lower Towns led to the Red Stick War (Creek War, 1813–1814); begun as a civil war within the Muscogee Nation, it enmeshed the Northern Creek Bands in the War of 1812 against the United States while the Southern Creeks remained US allies. General Andrew Jackson then seized the opportunity to use the rebellion as an excuse to make war against all Creeks once the northern Creek rebellion had been put down with the aid of southern Creeks. The result was a weakening of the Creek Nation and the forced ceding of Creek lands to the US.

Blood Creek

Blood Creek, previously known as Creek and Town Creek, is a horror film directed by Joel Schumacher, starring Michael Fassbender as the main antagonist and written by Dave Kajganich. The film had a limited theatrical release on September 18, 2009. The film also stars Dominic Purcell and Henry Cavill as brothers on a mission of revenge who become trapped in a harrowing occult experiment dating back to the Third Reich.

Plot

In 1936, a German professor, Richard Wirth, is hosted by the Wollners, a family of German emigrants in West Virginia. The Wollners believe him to be a visiting scholar, but Wirth turns out to be a Nazi occultist who seeks a Viking runestone buried on their property. When Wirth reveals he wants to use it for evil, he is interrupted by the family, who trap him in their basement and bind him through a ritual that requires frequent human sacrifices. Linked to Wirth, the family survive through the decades, operating as both captors and servants to Wirth, who they keep weakened.
