Fluvial processes
A river can move its load via four processes: traction, saltation, suspension, and solution. Solution – minerals are dissolved in the water and carried along in solution. This typically occurs in areas where the underlying bedrock is limestone or chalk. Suspension – fine, light material such as alluvium is carried in the water. This is ...

11.1: The Dissolution Process
The Formation of Solutions. The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without the requirement of energy from some external source.Sometimes a mixture is stirred to speed up the dissolution process, but this is not necessary; a homogeneous solution will form eventually.
