What is the upper stage of the river?
The Upper Stage The upper stage of a river is also called the youthful stage or mountain stage. The velocity and speed of the stream are very high because the slope here is steep. The vertical erosion is the most dominant work here. The valley is formed here.
What are the 3 stages of a river course?
Nearly all rivers have an upper, middle, and lower course.
- Young River – the upper course.
- Middle Aged River – the middle course.
- Old River – the lower course.
What are the 4 stages of a river?
These categories are: Youthful, Mature and Old Age. A Rejuvenated River, one with a gradient that is raised by the earth’s movement, can be an old age river that returns to a Youthful State, and which repeats the cycle of stages once again. A brief overview of each stage of river development begins after the images.
What are the stages in a river course?
3 Stages of a River
- YOUTHFUL STAGE (UPPER COURSE) – V- Shaped Valley > Erosion.
- MATURE STAGE (MIDDLE COURSE) – Meanders > Erosion and Deposition.
- OLD AGE STAGE (LOWER COURSE) – Floodplains > Deposition.
- Advantages. Scenic Attraction.
- Dangers. Flooding – Damage to property, land, animals and homes.
Is the upper course of a river deep?
Upper course – this is where the river starts and is usually an upland area. Slopes are steep – this can increase the velocity of the river after heavy rainfall, when discharge is high. The river channel is narrow and shallow here.
What do you mean by upper course?
The upper course of a river is where the river begins its path toward the sea. This part of the river arguably has the most landscape features, and biggest range of physical features.
What is Trough stage of river?
Trough stage: In this stage, the cross-section of the river is made up of alluvial sand and silt. The bed slope and velocity are small. In this stage, seepage losses are less that’s why the most suitable location of canal headworks is in this stage.
What is Boulder stage of river?
Boulder stage: In this stage the bed is made up of a mixture of sand, shingle, gravel and boulders. As the bed material is very pervious there exists good amount of subsoil water flow. Rivers in this stage have straighter courses with wide bed and non-submersible banks.
What is a river course of the river?
The course of a river is the direction in which a river flows. You must remember that all rivers flow downhill. We can find 3 different courses in a river: upper, middle and lower course.
What are the landforms in the upper course 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.
Where is the upper course of a river located?
The upper course of a river is where the river begins its path toward the sea. This part of the river arguably has the most landscape features, and biggest range of physical features. Features of a river’s upper course: Source – This is where the river begins.
What is a flashy river?
A “flashy” stream is one that experiences a rapid increase in flow shortly after onset of a precipitation event, and an equally rapid return to base conditions shortly after the end of the precipitation event.
What is the upper stage of a river called?
The upper stage of a river is also called the youthful stage or mountain stage. The velocity and speed of the stream are very high because the slope here is steep. The vertical erosion is the most dominant work here. The valley is formed here. The place where a river starts is called a source.
What is the course of a river?
The course of a river includes the upper stage, the middle stage, and the final stage. The course of a river includes the upper stage, the middle stage, and the final stage. Each stage of the river is dominated by a kind of work.
What are the three stages of a river?
Most rivers have an upper (youthful) course, a middle (mature) course and a lower (old age) course. These stages are marked by variations in the characteristics of the river.
What is the youthful stage of the river?
The youthful stage of the river is when water flow is the quickest. Waterfalls, potholes, V-shaped valleys and interlocking spurs are features of the youthful stage, and these features are due to erosion.
