What does graded mean in geography?

The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality.

What does a graded river mean?

“A graded river is one in which, over a period of years, slope and channel characteristics are. delicately adjusted to provide, with available discharge, just the velocity required for the. transportation of the load supplied from the drainage basin.

How does a stream become graded?

Over time, the river becomes increasingly balanced. The factors that make a river larger and the factors that make a river smaller balance out. This is when it becomes a graded stream.

What is graded stream?

A stream is said to be at grade when it is neither eroding nor depositing material at any point along its course. In this condition, the thalweg (q.v.) or longitudinal profile consists of a continuous concave curve or curves just steep enough to transport all the load from one end to the other.

What is a ungraded river?

Ungraded Profile. Page 3. Is a river profile that has irregularities/obstruction/temporary base levels along its path (It is not. smooth)

What is a stream in geography?

A stream is a body of water that flows on Earth’s surface. The word stream is often used interchangeably with river, though rivers usually describe larger streams. Streams provide many benefits to humans.

What does it mean when a stream has a graded profile?

A graded stream is one in which, over a period of years, slope is delicately adjusted to provide, with available discharge and the prevailing channel characteristics, just the velocity required for transportation of all of the load supplied from above.

What is an ungraded stream?

Ungraded Profile. Page 3. Is a river profile that has irregularities/obstruction/temporary base levels along its path (It is not. smooth) Ultimate Base Level/Permanent Base Level.

What does it mean when a stream has a graded profile quizlet?

what is a graded stream? A stream with a balance between its processes. This is nearly impossible to attain so the concept is ideal.
