What are the main features formed by the river in its entire course? As a river enters a plain, it twists and turns forming large bends or meanders. Due to continuous erosion and deposition along the sides of the meander, the ends loop closer, and after a while, cut off from the river to form Ox-bow lakes.

Which feature is formed by the river in the middle course?
Meanders are typical landforms found in this stage of the river. A meander is a winding curve or bend in a river. They are typical of the middle and lower course of a river. This is because vertical erosion is replaced by a sideways form of erosion called LATERAL erosion, plus deposition within the floodplain.
What are the characteristics of the rivers in its lower course?
In the lower course, the river has a high volume and a large discharge. The river channel is now deep and wide and the landscape around it is flat. However, as a river reaches the end of its journey, energy levels are low and deposition takes place.
What are physical features of a river?
Rivers can flow down mountains, through valleys (depressions) or along plains, and can create canyons or gorges. The river channel typically contains a single stream of water, but some rivers flow as several interconnecting streams of water, producing a braided river.

What are the features made by a river in a floodplain?
Features such as oxbow lakes and seasonal wetlands are often a part of floodplains created through erosion and deposition. A meandering stream can contribute to a floodplain’s aggradation, or build-up in land elevation, as well as its erosion. A typical aggradation environment is a wide, shallow, braided river.
What is river Course?
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. Upper course: usually, rivers are born in mountains. The place where the river begins is called the source.
What is an essential feature of a river?
The water mass in rivers is in motion, unidirectional and sometimes of great force. Their outstanding function is the transport of water; with changes of discharge and velocity of water movement they erode the land and carry sediment and often bedload for, sometimes, long distances.
What is the middle course of a river called?
Unlike the relatively straight channel of the upper course, in the middle course there are many meanders (bends) in the river. A meander in general is a bend in a sinuous watercourse. A meander is formed when the moving water in a stream erodes the outer banks and widens its valley.
How is a river cliff and slip off slope formed?
The force of the water erodes and undercuts the river bank on the outside of the bend where water flow has most energy due to decreased friction. This will form a river cliff. On the inside of the bend, where the river flow is slower, material is deposited, as there is more friction. This will form a slip-off slope .
How are lower course rivers formed?
Lower course of a river
This is due to the contribution of water from tributaries. The river channel is deep and wide and the land around the river is flat. Energy in the river is at its lowest and deposition occurs. . Deltas are often found at the mouth of large rivers.
Which landforms would most likely be found in the lower course of a river?
Meanders usually occur in the middle or lower course, and are formed by erosion and deposition. As the river flows around a meander, centrifugal forces cause the water to flow fastest around the outside of the bend.
What is the main work of rivers in the lower course Class 9?
River flows considerably slow in the lower course. Main work of river in this course is deposition of sediments. The landforms formed by a river in the lower course are delta, distributaries, estuary and levee.
What is the main function of a river in its upper course?
The main function of a river in its upper course is erosion. It erodes its bed and banks and carries large boulders of rock with it. The landforms formed in the upper course of a river are V-shaped valley and waterfall.
What are the main features of a floodplain?
Characteristics of a flood plain include:
A large area of flat land either side of a river.
layers of alluvium cover the flood plain.
a river bluff along the edge of a flood plain.
meander scars.
levees.
rich, fertile soil.
reeds and marsh plants.
Why are floods so important in making floodplain landforms?
Flooding occurs naturally along every river and coastal areas. Flood waters can carry nutrient-rich sediments which contribute to a fertile environment for vegetation. In addition, floodplains are important because of storage and conveyance, protection of water quality, and recharge of groundwater.
What is a river cliff and how is it formed?
As a river goes around a bend, most of the water is pushed towards the outside. The lateral erosion on the outside bend causes undercutting of the bank to form a river cliff . Water on the inner bend is slower, causing the water to slow down and deposit the eroded material, creating a gentle slope.
What are the characteristics of a slip slope?
Freely meandering rivers
In a freely meandering river, a slip-off slope is characterized by a gentle slope composed of sand and pebbles on the inside convex bank of a meander loop, across the channel from a cut bank or river-cut cliff.
What feature is created when a waterfall retreats upstream?
The fallen rocks crash into the plunge pool . They swirl around, causing more erosion. Over time, this process is repeated and the waterfall moves upstream. A steep-sided gorge is formed as the waterfall retreats.
In which part of the course of the river potholes are formed?
Potholes form mainly in the upper course of the river, in high altitude where the river channel cuts directly into the bedrock. Potholes are the direct consequence of vertical erosion and processes of abrasion. This turbulence forces water down on to the bedrock. Over time small depressions within the bedrock develop.
In which course of the river floodplains are formed?
Complete Answer: Most floodplains are formed by deposition on the inside of river meanders and by overflow. Wherever the river meanders, the flowing water erosions the river bank on the outer side of the meander, while the sediments are simultaneously deposited in a point bar on the inside of the meander.
In which course of the river oxbow lakes are formed?
oxbow lake, small lake located in an abandoned meander loop of a river channel. It is generally formed as a river cuts through a meander neck to shorten its course, causes the old channel to be rapidly blocked off, and then migrates away from the lake.
What is the main work of river in the lower stage?
The Lower Stage
The main work of the river in this stage is the deposition. The depth of the river is shallow here. 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.
Why do rivers flood in the lower course?
Sediment held in suspension will settle out onto the floodplain creating rich alluvial soils. In periods of low discharge deposition will occur in the main channel itself. This causes the river bed to be raised and increases the risk of flooding.
