Explain fluvial transportation processes including traction, saltation, suspension and solution.

Fluvial transportation processes are essential for understanding how rivers move sediment. There are four main types: traction, saltation, suspension, and solution. Traction involves larger particles rolling along the riverbed, while saltation refers to smaller particles bouncing in a leapfrogging motion. Suspension occurs when fine particles are carried within the water, making the river appear muddy. Lastly, solution involves dissolved minerals being transported in the water. Each process plays a crucial role in shaping river landscapes and influencing sediment deposition downstream.
