What determines the size of a basin?

Drainage basins are divided from each other by topographic barriers called a watershed (Figure 10aa-1). A watershed represents all of the stream tributaries that flow to some location along the stream channel. The number, size, and shape of the drainage basins found in an area varies with the scale of examination.

What is another name for a drainage basin?

In America, a drainage basin is commonly called a watershed. It can also be called a drainage area, catchment basin, and water basin, to name a few.

How are drainage basins and watersheds similar?

Ridges and hills that separate two watersheds are called the drainage divide. The watershed consists of surface water–lakes, streams, reservoirs, and wetlands–and all the underlying groundwater. Larger watersheds contain many smaller watersheds.

How does drainage area size affect runoff?

Size. For a fixed return interval, as watershed size increases, the runoff per unit area decreases. This occurs primarily because average rainfall amount decreases with increasing area; secondarily, increased travel time for runoff allows more infiltration and other losses.

What drainage region in South America is the largest in the world?

South America has three important river basins: the Amazon, Orinoco, and Paraguay/Paraná. The Amazon River basin has an area of almost 7 million square kilometers (2.7 million square miles), making it the largest watershed in the world.

What is the difference between watershed and drainage basin?

Both river basins and watersheds are areas of land that drain to a particular water body, such as a lake, stream, river or estuary. In a river basin, all the water drains to a large river. The term watershed is used to describe a smaller area of land that drains to a smaller stream, lake or wetland.

What is the world’s largest watershed?

Where is the World’s Largest Watershed? The biggest watershed in the world is the Amazon River Basin with discharge greater than the next six largest rivers combined. The Amazon basin covers 2.7 million square miles and accounts for 20% of world’s total river flow; this watershed covers 40% of South America.

What is the longest body of water in North America?

It’s (1,200 miles) (1,800 km) in length. If then combined with its tributaries – the Slave, Peace and Finlay rivers – it extends to (2,635 miles) (4,240 km), and becomes the second longest river in North America, second only to the Mississippi/Missouri river system combination at (3,877 miles) (6,236 km) in length.

What is the largest basin?

Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world’s ocean basins. All of the world’s continents could fit into the Pacific basin. The Pacific is the oldest of the existing ocean basins.

Which river has largest drift Basin in world?


Which river has the largest drift basin in the world?

The Mississippi River has the third largest drainage basin in the world, exceeded in size only by the watersheds of the Amazon and Congo Rivers.

Why is it called Great Basin?

These mountains are coined a “desert mountain island” because they are surrounded by a “sea” of desert. This region is called the Great Basin because the streams and rivers have no outlet to the sea; instead, water collects in salt lakes, marshes and mud flats, where it eventually evaporates.

Is the Great Basin Desert Hot or cold?

Located in the Forty Mile Desert, precipitation is rare, and summers are hot, though temperatures are more moderate than those in deserts like the Mojave and Sonoran, due to the region’s higher elevation and latitude. Winters in this section of the basin are still cold, however.

What is a basin in geology?

A geological basin is a large low-lying area. It is often below sea level. Geological basins are one of the two most common places inland which collect sediment (the other is lakes).

What determines which drainage basin a person lives in?

Land and water are ecologically linked in a natural system called a catchment, drainage basin, or watershed. One important truth about watersheds is that we all live downstream from someone, and upstream from someone else. Anything dumped on the ground in the watershed can end up in its rivers, lakes or wetlands.

How does drainage basin affect flooding?

This will produce a high peak discharge and can lead to flash floods. The permeability of the soil and rock in a drainage basin is a big factor in flooding. If a basin has very dense vegetation cover, the vegetation will intercept precipitation and store it, reducing the volume of water entering a river.

How do drainage basins work?

Drainage basin, also called Catchment Area, or (in North America) Watershed, area from which all precipitation flows to a single stream or set of streams. The boundary between drainage basins is a drainage divide: all the precipitation on opposite sides of a drainage divide will flow into different drainage basins.

What is the difference between drainage and drainage basin?

The drainage basin acts like a funnel, collecting all the water within the area covered by the basin and channelling it into a waterway. Drainage basins drain into other drainage basins in a hierarchical pattern, with smallersub-drainage basins combining into larger drainage basins.

What is drainage basin class 9?

Class 9 : Key Concepts – Drainage. ‘Drainage’ is a term signifying the river system of an area. A drainage basin or river basin is an area which is drained by a single river system. An upland that separates two drainage systems that are next to each other is called a water divide.
