A tidal course is any elongated indentation or valley in a wetland originated by tidal processes, or having another origin, along which water flows pumped by tidal influence.
A valley is a low area between hills or mountains typically with a river running through it. In geology, a valley or dale is a depression that is longer than it is wide. The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of these two main types or a mixture of them, at least with respect to the cross section of the slopes or hillsides.
A wetland is a distinct ecosystem that is inundated by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a number of functions, including water purification, water storage, processing of carbon and other nutrients, stabilization of shorelines, and support of plants and animals. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life. Whether any individual wetland performs these functions, and the degree to which it performs them, depends on characteristics of that wetland and the lands and waters near it. Methods for rapidly assessing these functions, wetland ecological health, and general wetland condition have been developed in many regions and have contributed to wetland conservation partly by raising public awareness of the functions and the ecosystem services some wetlands provide.
A tidal course is a general denomination that includes a series of indentations within a wide spectrum of sizes (width, length and depth) and with at least two levels of inundation. Examples of tidal courses are tidal rills, tidal grooves, tidal gullies, tidal creeks and tidal channels. The first three are small features that normally do not contain water even during neap low tide, whereas creeks and channels have water permanently.
A river delta is a landform that forms from deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or another river that cannot carry away the supplied sediment. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment, and receiving basin processes that redistribute, sequester, and export that sediment. The size, geometry, and location of the receiving basin also plays an important role in delta evolution. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide coastline defense and can impact drinking water supply. They are also ecologically important, with different species' assemblages depending on their landscape position.
The Raritan River is a major river of central New Jersey in the United States. Its watershed drains much of the mountainous area of the central part of the state, emptying into the Raritan Bay on the Atlantic Ocean.
An inlet is an indentation of a shoreline, usually long and narrow, such as a small bay or arm, that often leads to an enclosed body of salt water, such as a sound, bay, lagoon, or marsh.
A body of water or waterbody is any significant accumulation of water, generally on a planet's surface. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.
Bow Back Rivers or Stratford Back Rivers is a complex of waterways between Bow and Stratford in east London, England, which connect the River Lea to the River Thames. Starting in the twelfth century, works were carried out to drain Stratford Marshes and several of the waterways were constructed to power watermills. Bow Creek provided the final outfall to the Thames, and the other channels were called Abbey Creek, Channelsea River, City Mill River, Prescott Channel, Pudding Mill River, Saint Thomas Creek, Three Mills Back River, Three Mills Wall River and Waterworks River.
The River Blackwater is a river in Essex, England.
The Kingsbridge Estuary in the South Hams area of Devon, England runs from Kingsbridge in the north to its mouth at the English Channel near Salcombe and lies between Bolt Head and Sharpitor to the west and Portlemouth Down to the east. The estuary is some 8.6 kilometres (5.3 mi) in length, with numerous side channels. Several of its creeks have independent names, including Blanksmill, Frogmore, Southpool, Batson and Bowcombe Creek.
Tidal race or tidal rapid is a natural occurrence whereby a fast-moving tide passes through a constriction, resulting in the formation of waves, eddies and hazardous currents. The constriction can be a passage where the sides narrow, for example the Gulf of Corryvreckan and the Saltstraumen maelstrom, or an underwater obstruction, such as is found at the Portland Race.
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, and flushes salts from inland soils. Tidal creeks are characterized by slow water velocity resulting in buildup of fine, organic sediment in wetlands. Creeks may often dry to a muddy channel with little or no flow at low tide, but with significant depth of water at high tide. Due to the temporal variability of water quality parameters within the tidally influenced zone, there are unique biota associated with tidal creeks which are often specialised to such zones. Nutrients and organic matter are delivered downstream to habitats normally lacking these, while the creeks also provide access to inland habitat for salt-water organisms.
An artificial whitewater course (AWWC) is a site for whitewater canoeing, whitewater kayaking, whitewater racing, whitewater rafting, playboating and slalom canoeing with artificially generated rapids.
The Nanticoke River is a tributary of the Chesapeake Bay on the Delmarva Peninsula. It rises in southern Kent County, Delaware, flows through Sussex County, Delaware, and forms the boundary between Dorchester County, Maryland and Wicomico County, Maryland. The tidal river course proceeds southwest into the Tangier Sound, Chesapeake Bay. The river is 64.3 miles (103.5 km) long. A 26-mile ecotourism water trail running along the River was set aside in July 2011 by Delaware state and federal officials, contiguous with a 37-mile water-trail extending through Maryland to the Chesapeake Bay.
Aike Beck or the Lockington Navigation was a stream in the East Riding of Yorkshire, England, which was constructed as a navigation in the late 18th century, and ceased to function as such in the 1850s. The water supply came from Bryan Mills Beck and Scorborough Beck, but in 1988, these were diverted to feed into Arram Beck, and most of the channel was filled in with material from the flood banks.
Iron Cove Creek, a southern tributary of the Parramatta River, is an urban stream west of Sydney Harbour, located in the inner-western Sydney suburbs of Croydon, Ashfield, Haberfield and Five Dock in New South Wales, Australia.
The Loders Creek is a stream and tidal creek which flows through the suburbs of the Gold Coast of South East Queensland, Australia. The creek is 8.3 kilometres (5.2 mi) long, and forms part of The Broadwater estuary catchment area.
Black Creek is a 13.0-mile-long (20.9 km) tributary of the St. Johns River. It is located in Clay County, Florida. Black Creek has two major tributaries; North Fork Black Creek and South Fork Black Creek. North Fork originates as an outflow from Kingsley Lake and flows north and then east through Camp Blanding and Jennings State Forest, meeting South Fork in Middleburg, Florida. North Fork Black Creek has Yellow Water Creek and Big Branch as its main tributaries. South Fork Black Creek is fed by areas of wetlands and numerous small streams. The confluence of North Fork Black Creek and South Fork Black Creek near Middleburg form the main channel of Black Creek.
Ennore is a neighbourhood in Chennai, India. Ennore is situated on a peninsula and is bounded by the Korttalaiyar River, Ennore creek and the Bay of Bengal. The creek separates Ennore from the Ennore Port and Athipattu Pudunagar. The neighbourhood is served by Ennore railway station. It was recently merged with Chennai City, of which it now forms the 1st ward. Over the years Ennore has become the hub of a range of industrial projects, mainly thermal power stations, fertilizer factories, industrial ports and coal yards.
Haslams Creek, a southern tributary of the Parramatta River, is a creek west of Sydney Harbour, located in Sydney, Australia. It flows through Sydney Olympic Park and joins Parramatta River at Homebush Bay.
A stream is a body of water with surface water flowing within the bed and banks of a channel. The stream encompasses surface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls.
Matanzas Bay is a saltwater bay in St. Johns County, Florida; the entrance to the bay from the South Atlantic is via St. Augustine inlet. Bodies of water that connect to the bay in addition to the South Atlantic are clockwise from the inlet:
