River Processes: erosion, transportation and deposition
There are four main processes of erosion that occur in rivers. These are: corrosion. Hydraulic action. The pressure of water breaks away rock particles from the river bed and banks. The force of the water hits river banks and then pushes water into cracks. Air becomes compressed, pressure increases and the riverbank may, in time collapse.
How do rivers erode? - Internet Geography
The diagram below shows how erosion impacts the bed and banks of a river channel, causing vertical and lateral erosion. Lateral and vertical erosion Vertical erosion involves the deepening of the river bed.
7.1 Overview of Runoff and Water Erosion Processes
The three stages of water erosion as a function of flow velocity are depicted for different particle sizes in a helpful diagram called the Hjulström-Sundborg diagram (Fig. 7‑6). Based on work of researchers at the University of Uppsala in Sweden, this diagram summarizes the behavior of particles in a stream or river [3].

Exercise 13.3 Understanding the Hjulström-Sundborg Diagram. Refer to the Hjulström-Sundborg diagram (Figure 13.16) to answer these questions. 1. A fine sand grain (0.1 mm) is resting on the bottom of a stream bed. (a) What stream velocity will it …

Erosion is the process that wears away the river bed and banks. Erosion also breaks up the rocks that are carried by the river. There are four types of erosion: Hydraulic action - This is...
For each of the processes of erosion and transportation draw a diagram show the process at work In the upper course of the main process is Erosion. This is where the bed and banks of the river are worn away. A river can erode in one of four ways: Process Definition Diagram Hydraulic action the sheer force of water hitting the banks of the river:

There are several different ways in which river erosion can happen, depending on the type of river and how fast it flows. Types of River Erosion. There are four types of river erosion, these are: Abrasion - This is when small rocks and pebbles are pushed along the bed of a river by the speed and intensity of the current. Over time, this has a ...
