In geography, an arm is a narrow extension, inlet, or smaller reach, of water flowing out from a much larger body of water, such as an ocean, a sea, or a lake. Although different geographically, a sound or bay may also be called an arm.
Both the tributary and distributary of a river are sometimes called an "arm". By extension, a canal arm is a subsidiary branch of a canal or inland waterway. A number of place names are derived from this term, such as Salmon Arm, Indian Arm and Alice Arm.
The Ganges is a trans-boundary river of Asia which flows through India and Bangladesh. The 2,525 km (1,569 mi) river rises in the western Himalayas in the Indian state of Uttarakhand. It flows south and east through the Gangetic plain of North India, receiving the right-bank tributary, the Yamuna, which also rises in the western Indian Himalayas, and several left-bank tributaries from Nepal that account for the bulk of its flow. In West Bengal state, India, a feeder canal taking off from its right bank diverts 50% of its flow southwards, artificially connecting it to the Hooghly River. The Ganges continues into Bangladesh, its name changing to the Padma. It is then joined by the Jamuna, the lower stream of the Brahmaputra, and eventually the Meghna, forming the major estuary of the Ganges Delta, and emptying into the Bay of Bengal. The Ganges–Brahmaputra–Meghna system is the second-largest river on earth by discharge.
The Manchester Bolton & Bury Canal is a disused canal in Greater Manchester, England, built to link Bolton and Bury with Manchester. The canal, when fully opened, was 15 miles 1 furlong (24 km) long. It was accessed via a junction with the River Irwell in Salford. Seventeen locks were required to climb to the summit as it passed through Pendleton, heading northwest to Prestolee before it split northwest to Bolton and northeast to Bury. Between Bolton and Bury the canal was level and required no locks. Six aqueducts were built to allow the canal to cross the rivers Irwell and Tonge and several minor roads.
The Calumet River is a system of heavily industrialized rivers and canals in the region between the south side of Chicago, Illinois, and the city of Gary, Indiana. Historically, the Little Calumet River and the Grand Calumet River were one, the former flowing west from Indiana into Illinois, then turning back east to its mouth at Lake Michigan at Marquette Park in Gary. Now the system is part of the Chicago Area Waterway System and through the use of locks flows away from Lake Michigan to the Cal-Sag Channel.
An inlet is a indentation of a shoreline, such as a small arm, bay, sound, fjord, lagoon or marsh, that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea.
The Great Miami River is a tributary of the Ohio River, approximately 160 miles (260 km) long, in southwestern Ohio and Indiana in the United States. The Great Miami originates at the man-made Indian Lake and flows south through the cities of Sidney, Piqua, Troy, Dayton, Middletown and Hamilton.
The Buckingham Canal is a 796 kilometres (494.6 mi)-long fresh water navigation canal, that parallels the Coromandel Coast of South India from Kakinada City in the Kakinada district of Andhra Pradesh to Village near Chidambaram, Cuddalore District of Tamil Nadu, India. The canal connects most of the natural backwaters along the coast to Chennai (Madras) port.
The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California. The river's main stem is about 73 miles (117 km) long. Its length to its most distant headwater tributary is just over 210 miles (340 km). The main stem Feather River begins in Lake Oroville, where its four long tributary forks join—the South Fork, Middle Fork, North Fork, and West Branch Feather Rivers. These and other tributaries drain part of the northern Sierra Nevada, and the extreme southern Cascades, as well as a small portion of the Sacramento Valley. The total drainage basin is about 6,200 square miles (16,000 km2), with approximately 3,604 square miles (9,330 km2) above Lake Oroville.
In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While channel typically refers to a natural formation, the cognate term canal denotes a similar artificial structure.
The Hooghly River or popularly called Ganga or Kati-Ganga in the Puranas, is a river that rises close to Giria, which lies north of Baharampur and Palashi in Murshidabad. It is the western distributary of the Ganges. The main course of the Ganges then flows into Bangladesh as the Padma. A man-made canal, built in the 1960s and early-1970s at Farakka, connects the Ganges, flowing through Malda, to the Hooghly to bring the abundant waters of the Himalayan river to the comparatively narrow river that rises in eastern West Bengal.
Burrard Inlet is a relatively shallow-sided fjord in northwestern Lower Mainland, British Columbia, Canada. Formed during the last Ice Age, it separates the City of Vancouver and the rest of the lowland Burrard Peninsula to the south from the coastal slopes of the North Shore Mountains, which span West Vancouver and the City and District of North Vancouver to the north.
The Stourbridge Canal is a canal in the West Midlands of England. It links the Staffordshire and Worcestershire Canal with the Dudley Canal, and hence, via the Birmingham Canal Navigations, to Birmingham and the Black Country.
Brunswick River is an open mature wave dominated barrier estuary, located in the Northern Rivers region of New South Wales, Australia.
The Wendover Arm Canal is part of the Grand Union Canal in England, and forms part of the British canal system. It is usually known as the Wendover Canal, but historically its builders referred to their branch canals as Arms, hence its historical name of Wendover Arm. It was planned as a feeder to carry water from springs near the town of Wendover in Buckinghamshire to the main line of the Grand Junction Canal at Bulbourne near Startops End in Hertfordshire, but when it opened in 1799 it was made navigable, as the extra cost of making it was so small. Water supplies from Wendover were found to be inadequate, and a series of reservoirs were built. A pumping station at Whitehouses was superseded by the Tringford pumping station in 1817; its steam engines were replaced by diesel engines in 1911 and then by electric pumps.
Portland Inlet is an inlet of the Pacific Ocean on the north coast of British Columbia, Canada, approximately 55 km (34 mi) north of Prince Rupert. It joins Chatham Sound opposite the Dixon Entrance. It is 4 km (2.5 mi) long and as much as 13 km (8.1 mi) wide. It drains the Portland Canal, Nass Bay, and Khutzeymateen Inlet, among others, and is the site of Pearse Island and Somerville Island. Other major sidewaters of the inlet are Observatory Inlet and its east arm, Alice Arm.
The Beaver and Erie Canal, also known as the Erie Extension Canal, was part of the Pennsylvania Canal system and consisted of three sections: the Beaver Division, the Shenango Division, and the Conneaut Division. The canal ran 136 miles (219 km) north–south near the western edge of the state from the Ohio River to Lake Erie through Beaver County, Lawrence County, Mercer County, Crawford County, and Erie County, Pennsylvania.
The New River is a tidal estuary in South Florida, United States. Despite its name, it is not a river, but a channel composed of many tributary canals, The channel is connected to the Everglades through a series of man-made canals. After passing through Fort Lauderdale, the channel connects to the Intracoastal Waterway and Atlantic Ocean at Port Everglades cut. The channel is entirely within Broward County and is composed from the junction of three main canals which originate in the Everglades, splitting off from the Miami Canal. They are the North New River Canal, which flows south from Lake Okeechobee along the east side of U.S. 27 and then east along the north side of State Road 84 / Interstate 595; the South New River Canal, which flows east from the Miami Canal along the north side of Griffin Road and the south side of Orange Drive; and a canal which flows east along the south side of Sunrise Boulevard.
Observatory Inlet is an inlet on the North Coast of British Columbia. It is a northward extension of Portland Inlet, other branches of which include the Portland Canal. The entrance of Observatory Inlet, from Portland Inlet, lies between Ramsden Point and Nass Point. Ramsden Point also marks, to the west, the entrance of Portland Canal. Observatory Inlet was named by George Vancouver in 1793, because he set up his observatory on the shore of the inlet, at Salmon Cove, in order to calibrate his chronometers. His two vessels, HMS Discovery and HMS Chatham, stayed in Salmon Cove from July 23 to August 17, 1793. During this time a boat surveying expedition under Vancouver himself explored Behm Canal. Vancouver also named three headlands at the entrance of Observatory Inlet: Maskelyne Point, for Nevil Maskelyne, the Astronomer Royal, Wales Point, for William Wales, the mathematical master who sailed with James Cook, and Ramsden Point, after the famed mathematical instrument-maker Jesse Ramsden.
The Kitsault River is a river on the North Coast of British Columbia, Canada, located at the head of Alice Arm, which is the east arm of Observatory Inlet, which is itself an arm of Portland Inlet. Located at the mouth of the river are the localities of Alice Arm, Kitsault and Gits'oohl, a community of the Nisga'a people which was the Gitzault Indian Reserve No. 24 prior to the Nisga'a Treaty.
Hastings Arm is a fjord on the North Coast of British Columbia, which is the northwest arm of Observatory Inlet, one of the two main branchings of Portland Inlet, the other being the better-known Portland Canal, which forms part of the Canada–United States border. Hastings Arm is approximately 30 km (19 mi) in length from the divergence of Observatory Inlet near the former smelting town of Anyox, where a 25 km (16 mi) east arm, Alice Arm, branches off towards its head at the mouth of the Kitsault River. This divergence is approximately 50 km (31 mi) from the mouth of Observatory Inlet itself, near Nass Bay, which is the outer part of the estuary of the Nass River. At the head of Hastings Arm is the mouth of the Kshwan River, and the Nisga'a village-site of Kswan.
