What affects the volume of a river?

There are several factors that affect the discharge of rivers at any given time. These factors include the size of the drainage area (or watershed), climate, land use/land cover, soil type, and the topography of the watershed.

What are the 4 parts of a river?

What factor does river depend?

Important factors include the following :

• The velocity of water: Erosion and transportation are both maximum when velocity is high. …
• The volume of water: The larger the volume of water, the greater is the power of erosion and transportation. …
• Load: Load is the material transported by a river.

What 3 factors affect how fast a river flows?

The velocity of a river is determined by many factors, including the shape of its channel, the gradient of the slope that the river moves along, the volume of water that the river carries and the amount of friction caused by rough edges within the riverbed.

What is the volume of the river?

Volume of Earth’s Rivers

What is the volume of water in a river called?

Volumetric flow rate, also known as discharge, volume flow rate, and rate of water flow, is the volume of water which passes through a given cross-section of the river channel per unit time.

What makes a river flow?

A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas.

What are the features of a river?

Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Middle course river features include wider, shallower valleys, meanders, and oxbow lakes. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.

What determines the direction a river flows?

The direction of flow is determined mostly by the area’s topography located between the headwater (origin) and mouth (destination). Also, rivers not only follow one direction; some turn and twist in several directions. It is important to note that a compass direction does not influence the flow of a river.

How do you determine the flow of the river in a map?

Quote from video:When a contour line crosses a stream the contour line bends and forms a V. This is significant because the tip of the V. Shows you where the water is coming from.

Does a river always flow the same way?

Rivers haven’t always flowed in the same directions as they do today. Rivers have a tendency to change with the landscape as mountains are formed, sediment is deposited, and landforms drift apart.

What directions do most rivers flow?

Rivers flow in one direction all over the world, and that direction is downhill. Across the central and eastern United States, it is rare for rivers to flow north because the slope of the land is toward the south and east.

Which river cut the equator twice?

The Congo River

The Congo River is 4,370 kilometres long when combined with the Lualaba, its largest tributary. It is the only big river in the world to pass across the equator twice.

What rivers flow uphill?

Antarctica river



There’s a river that flows uphill beneath one of Antarctica’s ice sheets, according to Robin Bell, a professor of geophysics at Columbia University’s Lamont-Doherty Earth Observatory in New York.

How many rivers flow north?

Are there only two rivers that flow north? When the subject of rivers flowing north comes up, a common misnomer that also comes up is that there are only two rivers in the world that flow north. Those mentioned are the Nile River in Africa and the St. John’s River in the United States.

What are the four rivers that flow north?

Rivers That Flow North

• Athabasca River, Canada, 765 miles.
• River Bann, Northern Ireland, 80 miles.
• Bighorn River, U.S., 185 miles.
• Cauca River, Colombia, 600 miles.
• Deschutes River, U.S., 252 miles.
• Essequibo River, Guyana, 630 miles.
• Fox River, U.S., 202 miles.
• Genesee River, U.S., 157 miles.

What is the only river that flows backwards?

The Chicago River

Illinois is home to the only river in the world that flows backwards. The Chicago River, known mainly for the different colors it is dyed to celebrate different events and holidays, has been a hallmark of Chicago since the earliest days of the city.

Do all rivers flow into the ocean?

Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.

Are all lakes salty yes or no?

D. For starters, lakes and rivers do contain salt, just not as much as the oceans. A large portion of those salts and minerals washes downstream into other rivers, or through the outlet stream or river of a lake, and eventually winds up in the oceans.

What landforms are formed by rivers?

The work of the river is mainly deposition, building up its bed and forming an extensive flood plain. Landforms like braided channels, floodplains, levees, meanders, oxbow lakes, deltas etc.

Do rivers end in lakes?

Quote from video:Where'd you rivers end rivers flow into larger rivers lakes or the ocean the flow of a river is directed by gravity water flows downhill most large rivers end where they meet the ocean.

Can a lake disappear?

Scientists and explorers have discovered lakes, rivers, and other waterways around the world that seem to disappear entirely. In some cases, sinkholes can cause entire lakes to disappear in a matter of days. In alpine areas and polar regions, cracks in ice sheets can burst glacial dams, draining lakes overnight.

Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.

Can a lake be drained?

Where does the water go when a lake is drained? Exorheic, or open lakes drain into a river, or other body of water that ultimately drains into the ocean.

Where does lake water go?

Because most of the world’s water is found in areas of highly effective rainfall, most lakes are open lakes whose water eventually reaches the sea. For instance, the Great Lakes’ water flows into the St. Lawrence River and eventually the Atlantic Ocean.

What is a Blake drain?

Blake drains (Ethicon, Sommerville, NJ) are white radiopaque silicone tubing with a solid core and four channels running the length of the drain (Fig 1). They are flexible, noncollapsible, round drains that exude constant suction over the length of the channels by capillary action.
