Question

Quizplus · Accepted Answer

Aggradation is the process by which sediment is deposited in a stream channel, typically when the sediment load exceeds the stream's capacity to transport it. This can result in the buildup of sediment in the streambed, sometimes leading to changes in the stream's course or other geomorphic features. Saltation refers to a type of sediment transport characteristic of sandy environments, in which individual grains are transported by wind or water in a hopping or bouncing motion. Degradation and downcutting both refer to processes by which a stream cuts downward into its channel, typically in response to increased streamflow or erosion of downstream areas.
