A Rivers Long Profile
Comic Panel 1
This is a rivers long profile; we can see all the features from source to mouth.

A river can be divided into three different stages:

Upper course - Start
Middle course
Lower course- End

Each stage is grouped by certain characteristics.

How will the river change from source to mouth?
River Processes
2 main types- Vertical and Lateral
4 main Processes- Corrasion, Attrition, Solution, Hydraulic Action
The river channel is different shapes along the course due to 3 processes:-
The amount of each process occuring creates different landforms.
Comic Panel 2
4 main Processes- Traction, Saltation, Suspension and Solution
Comic Panel 3
Deposition- occurs as the river slows, losing its energy and depositing its load. The heaviest material is deposited first, and then the lightest.
Comic Panel 4
River Processes
The river processes create features and patterns. We can describe the patterns through the long profile and a model called the Bradshaw model. There is a distinct pattern from source to mouth. With more erosion closer to the source and more deposition closer to the mouth.
River Discharge level
River discharge is the volume of water flowing through a river channel. This is the total volume of water flowing through a channel at any given point and is measured in cubic metres per second (cumecs).

The higher the discharge volume the more energy the river has to do the processes.
River Medway - Upper Course
The River Medway has a very small upper course with very small amounts of the features.
The upper course of a river includes features such as:

•V-shaped valleys & interlocking spurs

This is due to the rock types normally being very hard and vertical (downwards) erosion occurring.
