Hvítá (Árnessýsla)
Hvítá ( Icelandic , "white river") is a river in Iceland that begins at Hvítárvatn glacier lake on Langjökull glacier in the highlands of Iceland at . The river flows for before dropping down into a narrow gorge at Gullfoss waterfall. Thereafter, the river flows between Biskupstungur and Hrunamannahreppur districts. Here, Hvítá combines with three other rivers: Tungufljót , Brúará, and Stóra-Laxá , doubling the volume of the river. It proceeds to run through the flatlands near Grímsnes and behind Ingólfsfjall mountain. Just north of Selfoss town, it meets Sog River where it becomes Ölfusá as it flows into the Atlantic Ocean. Because of danger of flooding, especially during winter, Hvítá has a reputation of being the most dangerous river in Iceland. Organised rafting excursions take place on parts of the river. The river is bridged at 4 locations, thrice at the lowland and once near the source in the highland where it is only open over the summer. ...

Raft
A raft is any flat structure for support or transportation over water. It is usually of basic design, characterized by the absence of a hull. Rafts are usually kept afloat by using any combination of buoyant materials such as wood, sealed barrels, or inflated air chambers (such as pontoons), and are typically not propelled by an engine. Rafts are an ancient mode of transport; naturally-occurring rafts such as entwined vegetation and pieces of wood have been used to traverse water since the dawn of humanity. Human-made rafts Traditional or primitive rafts were constructed of wood or reeds. Modern rafts may also use pontoons, drums, or extruded polystyrene Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a ... blocks. Inflatable rafts up to the 20th century used flotation chambers ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Ölfusá
The Ölfusá () is a river in Iceland. It begins at the junction between the Hvítá and Sog rivers, just north of the town of Selfoss, and flows for 25 km into the Atlantic ocean. It is Iceland's largest river by volume with an average discharge of 423 m³/s. Its drainage basin is 5760 km2. The Ölfusá is home to a large salmon fishing industry. The Flói Nature Reserve is located on its eastern shore near its mouth. See also *List of rivers of Iceland On an island like Iceland, the rivers are short in length.

Sog River
Sog (; more commonly Sogið ) is a river in Iceland. It runs from the lake Þingvallavatn for to its confluence with the river Hvítá, forming the river Ölfusá which then runs for another 25 km into the Atlantic Ocean. Its average discharge is . There are three hydroelectric power stations on the riverLjósafossstöð (15 MW)Írafossstöð (48 MW) anSteingrímsstöð (27 MW). The river runs through two lakes, Úlfljótsvatn and Álftavatn . It has a healthy stock of arctic char and Atlantic salmon. The size of the char can be anywhere from 0.5 pounds up the 5.0 pounds with an average size of one pound. The most common weight for salmon is 5.0 to 10.0 pounds with a few fish caught each year from 20.0 to 30.0 pounds. There are also brown trout Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', '' Salmo'' and '' Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae.

Selfoss (town)
Selfoss () is a town in southern Iceland on the banks of the Ölfusá river. It is the seat of the municipality of Árborg. The Icelandic Route 1 (Iceland), Route 1 runs through the town on its way between Hveragerði and Hella, Iceland, Hella. The town is a centre of commerce and small industries with a population of 9000 (2021), making it the largest residential area in South Iceland.

Ingólfsfjall
Ingólfsfjall () is a tuya in Iceland in the vicinity of Hveragerði. Name The name is derived from Iceland's official first settler, Ingólfur Arnarson. The Medieval Landnámabók says that he passed here his third winter in Iceland after his arrival from Norway with his clan, and before his slaves found the columns of his high seat and he went to the region of Reykjavík to settle there. The source also states that the chief was buried within the small mound on top of Ingólfsfjall. Geology Ingólfsfjall consists mostly of basalt and palagonite and has its origin in subglacial eruptions which turned in the end subaerial and produced some lava at its top.Ari Trausti Guðmundsson, Pétur Þorleifsson: Íslensk Fjöll.

Brúará
The Brúará (, "bridge river") is a river of Iceland Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its s .... It is fed by springs and discharges at the Rótarsandur area and the Brúará Canyons. It is a right tributary of the Hvítá. The whole river course is designated as a nature protected area. The name comes from a type of natural bridge that overpassed the river near the bishup-seat in Skalholt. According to sources from the bishop a worker of the bishop broke the bridge in 1602 because the seat didn't want dirty wanderers to have it to easy to approach.

Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing s ...
