Transcript of Rivers
Streams and rivers that meander, follow the lowest level within the ground structure regardless of the direction.
Deposition is where the debris gets dropped on the inside edge of the river and builds up as the river moves on.

Rivers can be beautiful and relaxing but they can also be very unpredictable and dangerous.
Here is a picture of a river
In this picture it shows:

The source is the start of a river. It's normally the farthest point from the mouth. The source is usually a spring or a small stream. It is fresh water not salty like the sea.
Transportation is where the water picks up debris and moves it to a different position within the river.
Erosion is where the river eats away at the outer edge of the river and makes the river wider.
Impermeable means that the ground can't absorb the water, like clay or granite.
Permeable means that the ground can absorb the water like dirt and sand.
Wookey Hole is an example of how rivers can produce underground streams and caves by following the lay of the land.
To conclude I think that people have played a big part in regards to rivers and streams as deconstruction of land and development changes the structure of the ground.
This is what happened when a lake close to us overflowed.
Tributaries are smaller rivers that join onto the bigger one.
An Oxbow Lake is where a meander curves around a normal straight river and ends up like this.
The mouth is the end of a river that usually leads to an ocean or a lake. If to much water leads down to the lake or ocean then it will overflow.
This was near my House
Slow flowing river
Fast flowing river
The erosion is much greater on a fast flowing river because of the force of the water flowing and carrying away debris.
The deposition on a slow flowing river can lead to them having to be dredged due to build up of debris and restricted flow.
