River Landforms: Erosional & Depositional Features
Fluvial Dynamics: Understanding River Landforms and Evolution Table of Contents The Long Profile and the Three Stages Upper Course: Erosional Landforms Middle Course: Meanders and Migration Lower Course: Deposition and Flooding Check for Understanding In fluvial geography, we define landforms as the physical features on the Earth's surface created by the processes of erosion, transportation, and deposition. As a river travels from its source to its mouth, its energy levels change, leading to a distinct sequence of landforms across three primary stages. The Long Profile and the Three Stages The long profile of a river is a line representing the gradient of the river from source to mouth. Generally, this profile is a concave curve, showing a steep gradient in the upper course and a very gentle gradient near the sea. Val...
