The Madeira River is a major waterway in South America. It is estimated to be 1,450 km (900 mi) in length, while the Madeira-Mamoré is estimated near 3,250 km (2,020 mi) or 3,380 km (2,100 mi) in length depending on the measuring party and their methods. The Madeira is the biggest tributary of the Amazon, accounting for about 15% of the water in the basin. A map from Emanuel Bowen in 1747, held by the David Rumsey Map Collection, refers to the Madeira by the pre-colonial, indigenous name Cuyari.
The River of Cuyari, called by the Portuguese Madeira or the Wood River, is formed by two great rivers, which join near its mouth. It was by this River, that the Nation of Topinambes passed into the River Amazon.
The IJssel is a Dutch distributary of the river Rhine that flows northward and ultimately discharges into the IJsselmeer, a North Sea natural harbour. It more immediately flows into the east-south channel around the Flevopolder, Flevoland which is kept at 3 metres below sea level. This body of water is then pumped up into the IJsselmeer.
A distributary, or a distributary channel is a stream channel that branches off and flows away from a main stream channel. It is the opposite of a tributary, a stream that flows towards and into another stream or river. Distributaries are a result of river bifurcation and are often found where a river approaches a lake or an ocean and divides into distributary networks; as such they are a common feature of river deltas. They can also occur inland, on alluvial fans, or where a tributary stream bifurcates as it nears its confluence with a larger stream. In some cases, a minor distributary can divert so much water from the main channel that it can later become the main route.
The Red River, or sometimes the Red River of the South to differentiate it from the Red River in the north of the continent, is a major river in the Southern United States. It was named for its reddish water color from passing through red-bed country in its watershed. It is known as the Red River of the South to distinguish it from the Red River of the North, which flows between Minnesota and North Dakota into the Canadian province of Manitoba. Although once a tributary of the Mississippi River, the Red River is now a tributary of the Atchafalaya River, a distributary of the Mississippi that flows separately into the Gulf of Mexico. This confluence is connected to the Mississippi River by the Old River Control Structure.
The White River is an American two-forked river that flows through central and southern Indiana and is the main tributary to the Wabash River. Via the west fork, considered to be the main stem of the river by the U.S. Board on Geographic Names, the White River is 362 miles (583 km) long. Indiana's capital, Indianapolis, is located on the river. The two forks meet just north of Petersburg and empty into the Wabash River at Mount Carmel, Illinois.
The Clackamas River is an approximately 83-mile (134 km) tributary of the Willamette River in northwestern Oregon, in the United States. Draining an area of about 940 square miles (2,435 km2), the Clackamas flows through mostly forested and rugged mountainous terrain in its upper reaches, and passes agricultural and urban areas in its lower third. The river rises in eastern Marion County, about 55 miles (89 km) east-southeast of Salem. The headwaters are on the slopes of Olallie Butte in the Mount Hood National Forest, about 10 miles (16 km) north of Mount Jefferson, at an elevation of 4,909 feet (1,496 m) in the Cascade Range. The Clackamas flows briefly north and then flows northwest through the mountains, passing through North Fork Reservoir and Estacada. It then emerges from the mountains southeast of Portland. It joins the Willamette near Oregon City and forms the boundary between Oregon City and Gladstone.
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.
The Liao River is the principal river in southern Northeast China, and one of the seven main river systems in China. Its name is derived from the Liao region, a historical name for southern Manchuria, from which the Liaoning province, Liaodong Peninsula, and Liao dynasty also derive their names. The river is also popularly known as the "mother river" in Northeast China. Coursing 1,345 kilometres (836 mi) long, the Liao River system drains a catchment basin of over 232,000 square kilometres (90,000 sq mi), but its mean discharge is quite small at only about 500 cubic metres per second (18,000 cu ft/s), about one-twentieth that of the Pearl River. The Liao River has an exceedingly high sediment load because many parts of it flow through powdery loess.
The Payette River is an 82.7-mile-long (133.1 km) river in southwestern Idaho and a major tributary of the Snake River.
A river island is any exposed landmass surrounded by river water. Properly defined, it excludes shoals between seasonally varying flows and may exclude semi-coastal islands in river deltas such as Marajó.
River bifurcation occurs when a river flowing in a single channel separates into two or more separate streams which then continue downstream. Some rivers form complex networks of distributaries, typically in their deltas. If the streams eventually merge again or empty into the same body of water, then the bifurcation forms a river island.
The Whitewater River is a 16.6-mile-long (26.7 km) tributary of the Upper Mississippi River which flows through the Driftless Area of Minnesota, reaching its mouth in Wabasha County at the community of Weaver opposite Buffalo, Wisconsin. The nearest towns are Altura, Saint Charles, and Elba. The region hosts endangered native dry oak savannas, semiforested areas that seem to have been dependent on fire for their well-being.
The Xiliao or West Liao River is a river in Inner Mongolia and Liaoning province, in northeast China. Its source is the Xilamulun River in Inner Mongolia. It is one of the headwaters of the Liao River.
Oak Grove Fork Clackamas River is a 21-mile (34 km) tributary of the Clackamas River in the U.S. state of Oregon. From its headwaters in the Warm Springs Indian Reservation near Abbot Pass in the Cascade Range, the river flows generally west through Mount Hood National Forest in Clackamas County to the unincorporated community of Ripplebrook. Here it enters the main stem of the Clackamas River. Oak Grove Fork feeds Timothy Lake and Lake Harriet, two artificial impoundments built along its course to control water flows to hydroelectric plants.
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long, large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks.
The South Fork Eel River is the largest tributary of the Eel River in north-central California in the United States. The river flows 105 miles (169 km) north from Laytonville to Dyerville/Founders' Grove where it joins the Eel River. The South Fork drains a long and narrow portion of the Coast Range of California in parts of Mendocino and Humboldt counties. U.S. Route 101 follows the river for much of its length.
The Hoquiam River is a stream in the U.S. state of Washington. It has three main tributaries, the East Fork, West Fork, and Middle Fork Hoquiam Rivers. The main stem Hoquiam River is formed by the confluence of the West and East Forks. The Middle Fork is a tributary of the West Fork.
Salmon Falls Creek is a tributary of the Snake River, flowing from northern Nevada into Idaho in the United States. Formed in high mountains at the northern edge of the Great Basin, Salmon Falls Creek flows northwards 121 miles (195 km), draining an arid and mountainous basin of 2,103 square miles (5,450 km2). The Salmon Falls Creek valley served as a trade route between the Native American groups of the Snake River Plain and Great Basin. Today, most of its water is used for irrigation.
The Willamette River is a 187-mile (301 km) tributary of the Columbia River in the U.S. state of Oregon. The upper tributaries of the Willamette originate in mountains south and southeast of the twin cities of Eugene and Springfield. Formed by the confluence of the Middle Fork Willamette River and Coast Fork Willamette River near Springfield, the main stem meanders generally north from source to mouth. The river's two most significant course deviations occur at Newberg, where the stream turns sharply east, and about 18 miles (29 km) downriver from Newberg, where it turns north again. Near its mouth, the river splits into two channels that flow around Sauvie Island. The main channel enters the Columbia about 101 miles (163 km) from the larger stream's mouth on the Pacific Ocean, and the smaller Multnomah Channel enters the Columbia about 14.5 miles (23.3 km) further downstream near St. Helens in Columbia County.
Deep Creek is a tributary of Mahantango Creek in Dauphin County, Pennsylvania, in the United States. It is approximately 5.9 miles (9.5 km) long and flows through Lykens Township and Pillow. The watershed of the creek has an area of 10.6 square miles (27 km2). It is not designated as an impaired waterbody, but is nevertheless observed to have high nitrate concentrations. Major land uses in the creek's watershed include agricultural land and forested land. The creek's watershed is classified as a Warmwater Fishery.
