| Long Profile | This shows the how the gradient of the river changes over its whole course |
| Cross Profile | Shows the cross section of a river at a specific point in its course |
| Upper course | Steep gradient V-shaped valley with steep sides Narrow, shallow channel |
| Middle course | Medium gradient Gently sloping valley sides Wider, deeper channel |
| Lower course | Gentle gradient Very wide, almost flat valley Very wide, deep channel |
| Vertical Erosion | Deepens river valley and channel, making it v-shaped. Upper course |
| Lateral Erosion | Widens river valley and channel, middle and lower course. |
| Four processes of erosion | Hydraulic action- shear forces of water breaks up rocks Abrasion- rocks scrape and rub channel Attrition- rocks smash into each other and become round and smooth Solution- river dissolves some rocks and carries them |
| Four processes of transportation | Traction- large boulders boulders moved along river bed Saltation- |
