Which of the following rivers has the largest water discharge of any in the world?

The Amazon River discharges 7,380,765 cubic feet per second of water, and it represents 20% of the world’s riverine discharge into the ocean. The Amazon basin is now the largest water drainage basin in the world covering an area of 2,720,000 square miles.

Do gradients usually decrease downstream in a major river system?

Gradients usually decrease downstream in a major river system. Alluvium refers to stream deposits, mainly sand and gravel. The lowest base level for most streams is sea level. … Urbanization lowers peak discharges on small streams by routing the runoff directly to the stream.

Which of the following best describes how urbanization affects small stream watershed?

Which one of the following best describes how urbanization affects small-stream watersheds? Infiltration decreases; lag time between storms and peak runoff shortens.

How is sediment yield calculated?

The sediment yield from any drainage system is calculated by averaging the data collected over a period of years. It is, therefore, an average of the results of many different hydrologic events.

What is sediment yield ratio?

Sediment yield (SY) is defined as the amount of sediment leaving the watershed or catchment, and gross erosion is defined as the absolute amount of erosion occurring within the catchment.

Which is the third largest river in the world by discharge?

List of rivers by discharge

1 South America Amazon
2 Africa Congo (Zaire)
3 Asia Ganges/Brahmaputra/Meghna
4 South America Orinoco

Which is longest river in India?

At over three thousand kilometers long, the Indus is the longest river of India. It originates in Tibet from Lake Mansarovar before flowing through the regions of Ladakh and Punjab, joining the Arabian Sea at Pakistan’s Karachi port.

Which is longest river in the world?

  • Nile: 4,132 miles.
  • Amazon: 4,000 miles.
  • Yangtze: 3,915 miles.

Is the steepness or vertical drop over a specific distance of a stream?

gradient The steepness or vertical drop of a stream over a specific distance.
hot spring A spring formed where hot ground water flows to the surface.
hydrologic cycle The continuous circulation of water among the hydrosphere, the atmosphere, the biosphere, and the geosphere; also called the water cycle.

Why does channel gradient decrease downstream?

Gradient (the slope of the land) decreases as rivers flow because the river meanders across the land rather than erode into it and follow a straight path as it does in the source. This means it covers a decrease in height over a longer distance the further downstream you get.

When a stream suddenly drops in gradient This sudden drop off is called?

Alluvial Fans – When a steep mountain stream enters a flat valley, there is a sudden decrease in gradient and velocity. Sediment transported in the stream will suddenly become deposited along the valley walls in an alluvial fan.

How does urbanization affect drainage in a watershed?

Over the last two centuries, urbanization has caused changes in watershed hydrology that include declines in the natural filtering capacity of river systems (e.g., channelization of headwater streams, loss of floodplains and wetlands) and regulation of flows due to the construction of dams and impoundments.

Does urbanization increase or decrease peak stream flow?

Urbanization generally results in increased magnitude and frequency of peak flows. However, baseflow effects typically are more variable, with studies showing a range of responses in urban streams [Lerner 2002, Brandes et al.

what is the drop in water surface elevation divided by the distance the water flows?
what is the drop in water surface elevation divided by the distance the water flows?

How does urbanization affect runoff and infiltration?

The most important influence on direct runoff change was urban surface change caused by urbanization. Urbanization can cause a large amount of pervious surface to turn into impervious surface, changing the hydrologic cycle and reducing infiltration rates [45,46,47].

What is water yield?

Water Yield is defined as the average amount of fresh water that runs off in an unregulated watershed.

What sediment does a river carry with its flow?

For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification.

What determines the amount of sediment in a river?

In general, the greater the flow, the more sediment that will be conveyed. Water flow can be strong enough to suspend particles in the water column as they move downstream, or simply push them along the bottom of a waterway 11.

What is erosion and sedimentation?

Erosion is the process where soil particles are dislodged or detached and put in motion. 2. Sedimentation is the process whereby detached particles are deposited elsewhere.

What is river base level?

In geology and geomorphology a base level is the lower limit for an erosion process. … The height of a base level also influences the position of deltas and river terraces. Together with river discharge and sediment flux the position of the base level influences the gradient, width and bed conditions in rivers.

What is soil SDR?

Gravel / Soft Disintegrated Rock. (SDR)

What river has the largest mouth?

The biggest delta in the world is the Ganges Delta in Bangladesh and India. The delta is 350 kilometers (220 miles) along the Bay of Bengal. So many smaller rivers empty into the Ganges Delta, the area is sometimes called the “Mouths of the Ganges.” in large amounts.

Which river discharges most water into the ocean?

The Amazon River: The largest river by volume, the river Amazon, represents 20% of the global riverine discharge to the Atlantic Ocean. Also featuring the largest basin, it has a drainage area of 2,722,020 square miles.

Which rivers carry the most water?

The Nile is estimated to be between 5,499 kilometers (3,437 miles) and 6,690 kilometers (4,180 miles) long. There is no debate, however, that the Amazon carries more water than any other river on Earth. Approximately one-fifth of all the freshwater entering the oceans comes from the Amazon.

Which is largest river in Asia?

What river is longer Amazon or Nile?

The Amazon is considered the world’s largest river by volume, but scientists have believed it is slightly shorter than Africa’s Nile. The Brazilian scientists’ 14-day expedition extended the Amazon’s length by about 176 miles (284 kilometers), making it 65 miles (105 kilometers) longer than the Nile.

How do V-shaped valleys form quizlet?

A V-shaped valley is a narrow valley with steeply sloped sides that appear similar to the letter “V” from a cross-section. They are formed by strong streams, that have cut down into the rock through downcutting/stream erosion. These valleys form in streams in their upper course.
