River Processes and Profiles

Vocabulary flashcards covering river erosion, transportation, deposition, and valley profile characteristics based on the lecture notes.

Erosion

The process that wears away the landscape and provides material.

Transportation

The process that carries material downstream.

Deposition

The process where material settles and is distributed in new areas.

Abrasion

A type of river erosion process.

Hydraulic action

A type of river erosion process.

Attrition

A type of river erosion process.

Solution

A river process involved in both erosion and transportation.

Traction

A method of river transportation.

Saltation

A method of river transportation.

Suspension

A method of river transportation.

Upper course

The initial section of a river profile characterized by higher gradient and vertical erosion.

Middle course (Midalo course)

The middle section of a river profile characterized by some erosion and deposition.

Low course

The lower section of a river profile characterized by decreasing gradient, lateral erosion, and alluvium deposition.

Vertical erosion

Erosion occurring primarily in the upper course of a river.

Lateral erosion

Erosion occurring in the low course of a river.

Alluvium deposition

Deposition occurring in the low course of a river valley.

Gravity

The force responsible for pulling down water in a river.
