What are the three course of river?
3 Main Courses of River | India | Geography
- The Upper Course: In the mountainous course, a river passes through a steep slope.
- The Middle Course: As a river leaves the hilly area and enters into a plain, its middle course starts.
- The Lower Course: The last part of a river near its mouth is called the lower course.
What is upper course and lower course of a river?
Upper course river features include steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. Lower course river features include wide flat-bottomed valleys, floodplains and deltas.
What are the course of river explain with diagram?
The river is getting curvier with more gentle bends. And finally, the lower course. The lower course is the complete opposite of the upper course. In the lower course it has a shallow gradient, which means there is slow flow.
What is the lower course of a river called?
‘Lower course’ of the river includes floodplains and deltas. Lower course of river includes several land forms namely floodplain, Levee, estuary, and deltas. Rivers got flooded on a regular period of time.
What is the lower course of a river?
The lower course of the river is where the it comes to meet the sea at the mouth, and starts at the relatively straightening path preceeding it, surrounded by flat land. Features of the Lower Course of Rivers: High Volume and Discharge – At the lower course of a river, the river is at its biggest volume capacity.
Is formed in the lower course of a river?
Deltas are found at the mouth of large rivers – for example, the Mississippi. A delta is formed when the river deposits its material faster than the sea can remove it.
What is the main function of a river in its lower course is?
Answer: The volume of water in a river is at its greatest in lower course. This is due to the contribution of water from tributaries.
What is the main work of a river in lower stage?
The Lower Stage The main work of the river in this stage is the deposition. When the main river splits into many small rivers, they are called as the distributaries. The place where the river ends is called mouth of the river.
What is a middle course of a river?
The middle course of a river is found on gently sloping land, and is typically identified by its meandering path – the sweeping side to side curves. The middle course has two main features – meanders and ox-bow lakes.
What are the steps of a river?
River stages
| Stage | Main activity |
|---|---|
| Upper course (steep gradient) | Vertical (downward) erosion |
| Middle course (gentle gradient) | Lateral (sideways) erosion starts, transportation |
| Lower course (very low gradient) | Deposition |
What is the upper course of a river called?
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 is the upper course of a river?
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.
Why a river is most widely used source of water?
Rivers are used all over the world as sources of irrigation water. The flow of river fluctuates over time. The flows of some rivers fluctuate greatly over relatively short periods of time; these are mainly small local rivers which respond quickly to rainfall in their catchment area.
