Describe What are The River in Geography?
River water like a ribbon flows down from gravity. The river can be wide and deep, or deep enough for one to cross. The water that flows smaller than a river is called a stream, stream, or stream. Some rivers flow year-round, and others flow only during certain seasons or when there is heavy rainfall. Large rivers can be thousands of miles long. River erosion power can perform geologic wonders like the Grand Canyon.
Every river has a starting point where the water begins to flow. This spring is called headwater. Water may come from rain or snow in the mountains, but it can also leak out of the ground or build on the edge of a lake or a large lake. Another part of the river is called the mouth of the river, where water flows out of a body of water, such as a lake or the sea. Along the way, rivers may pass through wetlands where vegetation drains and filters pollutants.
The water that flows into the rivers is fresh, meaning less than 1 percent the salt. However, rivers still carry and distribute salts and nutrients that are vital to supporting plant and animal health. For this reason, some of the world’s most diverse ecosystems can be found near rivers. In total, scientists estimate that every river in the world carries 3.6 billion metric tons (4 billion tons) from land to sea each year.
Rivers can also form what are called harbors, where brackish water meets freshwater near the mouth of the river to form “salt water.” The Hudson River in New York, USA, is an example of a saltwater pipeline extending over 150 miles (150 miles) upstream.
Flowing rivers carry rocks, sand, and mud. As the river begins to recede — such as in swamps, off curves, or where the river extends, as in the mouth — these residues sink and form to form a delta. Rivers overflow its shores and flood the sewage. These deltas and floods are the most fertile agricultural areas that provide the greatest number of people around them. For example, in Egypt, the Nile River and its tributary helped to establish the Egyptian monarchy. Today, farmers in the floodplain in the Central Valley of California produce about one-third of all vegetables and two-thirds of the fruit and nuts consumed in the United States.
People use rivers for agricultural irrigation, drinking water, transport, power generation through hydroelectric dams, and recreational activities such as swimming and boating. Each of these uses can affect the health of the river and its surrounding environment. Monitoring the health of rivers, lakes, and streams is a vital task for scientists called limnologists.
What Are The River Examples in Geography?
New River: A steep river with very few rivers flowing fast. Its channels erode deeper than wider. Examples are the rivers Brazos, Trinity, and the Ebro.
Mature river: A river that has less beauty than smaller rivers and flows slowly. The old river is fed by many rivers and drains more water than the young river. Its channels are more erosive than deep. Examples are the Mississippi, Saint Lawrence, Danube, Ohio, Thames, and Paraná rivers.
Old river: A river with a low incline and low erosion. Old rivers are flooded. Examples are the Yellow, low Ganges, Tigris, Euphrates, Indus, and the lower Nile rivers.
Renewable river: A gradient river with elevated tectonic height. Examples are the Rio Grande and the Colorado River.
How river features differ between its upper and lower extremities is summarized in the Bradshaw model. The relationship of the law of gravity between the slope of the channel, the depth, and the width is given as a function of extracting the “river kingdom”.
Types of Rivers in Geography: Rivers are local phenomena where freshwater flows through dry land from one place to another. They also act as natural drainage systems. Rivers occur naturally on every continent in the world, including Antarctica.
Rivers play an important role in daily life and human activities, as well as in the flora and fauna that lives in and around them. Most of the ancient civilizations were found to be close to the great rivers, which served as an inexhaustible source of fresh drinking water and a means of transportation. Such a civilization includes; Rome, India, China, and Egypt.
Currently, electricity is generated at hydroelectric power plants (dams) built on rivers. They account for more than 25% of the world’s electricity supply and 30% of the world’s freshwater supply.
Every river has its own distinctive feature, as well as similarities. ” Every river has its source (the source of the river that includes streams, springs, etc.) and the mouth (canals like; sea, ocean, lake, another major river, or dessert).
The height of a river and its mouth are factors that determine its size and speed. The Amazon River is just one example, as it is the largest river in the world (recorded for up to 55 million gallons [55 million L] of water per second) and is one of the fastest-flowing rivers. its source is the Andres Mountains of Peru and flows into the Atlantic Ocean.
Many rivers tend to have several sources of water, including lakes, glaciers, tributaries, streams, and glaciers. Some large rivers have their source from the confluence of numerous small rivers. One of those areas is the Ohio River, which derives its source from the confluence of the Monlahela and Allegheny rivers. Rivers can be identified by their length, breadth, speed, and location
The Perennial River
An endless river is also called a permanent river. This means it is lifeless but continues to flow throughout the year. The height and flow rate of the river is influenced by the changing seasons (heavy rains or prolonged drought). Endless rivers tend to have stable sources that ensure their continuous flow. We find that in many cases, perpetual rivers are blocked to limit their flow, create dams, act as hydropower plants, irrigate, and improve flow. The first known dam ever built can be traced back to ancient Mesopotamia about 3,000 BC.
Sadly, the flow of some of the world’s most enduring rivers has declined over the past few decades. This is due to climate change and increased human exploitation of rivers for commercial and industrial purposes, as well as irrigation.
Periodic River
Occasional rivers are also known as central rivers. Rivers do not flow all year round but occasionally. Generally, they can only flow from one quarter to three-quarters of a year, and usually just a few days at a time.
Rivers sometimes occasionally have strong beams and beds, and sometimes have water beneath them. Their beds stay dry until a large amount of rain or melted snow increases the amount of water, either in the water source below it.
Rivers from time to time tend to have a predictable seasonal flow that remains the same throughout the years. Sometimes they have pools of water on their edges even when the rivers are not flowing.
Rivers can sometimes be too short or too long. One of those Ugab rivers in South Africa; reaches 310 miles long. These rivers have increased in number over the past fifty years due to nature and humanity (such as climate change, the exploitation of people by the endless rivers, and many more).
Episodic River
Episodic rivers only flow after a certain event (or episode as the name implies). These events may include; heavy rains, melting snow, and expanded flow channels. It can be a perpetual and occasional river in the sense that it has no stable source, groundwater, and is highly dependent on climate for its water supply.
Although Episodic rivers can flow briefly throughout the year, they are generally known to remain dry for years or even decades at a time. Another example of this is the Nossob River in the Kalahari region of South Africa more than 450 miles long. It has not been seen with a significant flow since the late 1980s.
Exotic River
Rare rivers are rivers that flow into arid areas where there is little or no water. These rivers, however, come from damp areas or mountains and flow through arid regions (deserts). Rare rivers may be continuous or occasional rivers.
Extraordinary rivers have also played a vital role in some of the world’s most important civilizations; providing people with drinking water, livestock, and irrigation in desert areas to produce food.
Ancient civilizations Lived on rare river banks including Egypt (Nile River), Mesopotamia (rivers Tigris and Euphrates), and China (Huang and Wei rivers). Nowadays, outdoor rivers are for transport and energy through hydropower plants.
Tributary River
The rivers flow, also known as the rich. They do not sink in the sea or in the sea, but they do enter into lakes or other rivers. Many of the world’s major rivers today are a tributary of the rest of the world.
An example of this is the Missouri River. It is the longest and strongest river in North America that stretches over 2,340 miles. It flows from the Rocky Mountains of Montana to St. Louis, Missouri, where it flows into the Mississippi River; making it the tributary Mississippi.
In many cases, the confluence of two different rivers gives birth to new offspring. Like the Ohio River in Pittsburg, Pennsylvania (a tributary of the Mississippi). It is built on the confluence of the Monongahela and Allegheny rivers.
Distributary River
Different rivers are exactly different from their tributaries, flowing from one river into many new ones. The point at which rivers separate from the main river is called the fork and the rivers that flow are called tunnels.
Dividing rivers usually have higher distances than their source, which may cause them to flow or drain faster. Usually, these rivers reunite with the river’s mother over time or divert them away. One example is the Atchafalaya River in Louisiana, which is the Mississippi distribution area.
Underground River
Subterranean rivers, are also known as underground rivers. These are rivers with beams and underground beds. They usually come from the river above the ground and travel long distances underground through caves. They may disappear into the holes to continue their path underground and later emerge above the ground.
The longest underground river ever recorded is the Sistema Sac Actum, which stretches for 95 miles through the Sac Actum cave system at Quinta Roo. One of those rivers is the Puerto Princesa Subterranean River in the Philippines known as a popular tourist destination.
Man-made Rivers (Aqueducts)
Drainage canals are man-made rivers that carry fresh water from a well (such as a lake, natural river, or lake) to where it is needed. They were built to irrigate large farms or provide drinking water to cities. Drainage can be found in cities such as; Egypt, India, Rome, China, and South America, and can supply more than 400 million gallons [400 million L] of water a day, depending on the volume.
Pipelines
Although piped rivers are relatively rare, they are man-made structures used to transport long-distance clean water. An excellent example is the Great Pipeline River in Libya. It starts at the Nubian Sandstone Aquifer runs underground across the Sahara Desert and covers more than 1,700 miles.
It provides more than 1,500 wells in its course and transports more than 1.5 billion gallons of water a day for irrigation and drinking. It serves millions of Libyans in the cities of Tripoli, Sirte, Benghazi, and surrounding areas, as well as twelve small towns and villages.
Rapids
Rapids (Whitewaters) are sections of the river that flow faster than other sections due to the steep slope of the river. They are built because of the flowing water that hits the rocks near the river bed, causing bubbles to form; turning the river white.
According to the American Whitewater Association, rapids have six stages on the International Difficulty scale. From Class 1; be quick to be gentle, and be able to accommodate strong swimmers, to the 6th grade; potentially fatal, urging the use of ransom.
Speed of varying intensity are found in rivers around the world, and will usually run continuously or intermittently for many miles. It is not uncommon for a single river to have a myriad of waves that vary in severity and phase.
Winding Rivers (Bending)
The winding river sections are very close to the rapids and usually do not move slowly with low-level beds. They are most common on the plains and lowlands. The winding sections of the river occur near the mouth of the river rather than at its source where the earth is shrinking as it approaches sea level.
Man controls currents by installing dams, canals, canals, and diversions in densely populated and low-lying areas to prevent flooding. And at the same time, they are achieving business and agricultural goals.
Creeks, Brooks, and Streams
Although there are no specific definitions of rivers. Streams, streams, and streams, however, are basically called small rivers. These types of rivers can be regular, occasional, episodic, tributary, or distributary, and have well-defined banks and beds. Sometimes their confluence can be a source of a large river.
Streams, streams, and streams can be very small or very long and can be important sources of fresh water. The Australian Billabong Creek (though the longest of its kind) covering more than 350 miles serves as a major impediment to the Edward River. Another example is Lodgepole Creek, United States.
Inland Waterways
The inland lane may refer to a river, part of a river, or a series of rivers used to transport people and goods by boat, or to other floating vessels.
Inland waterways are wide and deep enough to carry ship hulls, as well as slow navigation. They should not have rapids or waterfalls to prevent damage to vessels.
Another example is the inland United States waterway system, which covers more than 15,000 miles [25,000 km] of rivers and lakes.
