Youthful River
|
They erode it's channels deeper rather than wider. It flows very fast because of its steep gradient. It has a narrow straight channel. It has a smaller disharge than other types of rivers and has many rapids and water falls. It doesn't have many tributaries.
|
|
|
Mature River
|
It erodes it's channel wider rather than deeper. It's gradient isn't as steep as a youthful river and has less waterfalls and rapids. It has many tributaries. It has more discharge than a youthful river.
|
|
|
Old River
|
They have a low gradient and little eroasive power. It deposits dirt and rocks along it's channel. It has many bends, few waterfalls and rapids, and has fewer tributaries than a mature river because its smaller tributaries have formed together as part of the river.

Erosion
|
The processes by which wind, water, ice, or gravity transports soil and sediment from one location to another
|
|
|
Tributary
|
A stream that flows into a lake or into a larger stream.
|
|
|
Channel
|
The path that a stream follows.

River Basin
|
Drainage area of a river

Estuary
|

|
|
Riparian
|
Pertaining to the edges of streams or rivers.
|
|
|
Sediment
|
Eroded soil particles that wash or blow into rivers
|
|
|
Discharge
|
The amount of water that a stream or river carries in a given amount of time
|
|
|
Gradient
|
The measure of the change in elevation over a certain distance. The higher the gradient the faster it flows and the more erosive energy it has.
|
|
|
Load
|
The materials carries by a stream or river
|
|
|
Bed Load
|
Large materials such as boulders and pebbles that bounce along the river bed.
|
|
|
Suspended Load
|
Materials such as small rocks and soil carried within the river itself.
|
|
|
Dissolved Load
|
Materials that are dissolved in the water such as calcium and sodium.
