Aggradation is the process of sediment accumulation in a stream's bed when the load exceeds its capacity. This can lead to an increase in the stream's elevation and a decrease in its gradient as the sediment fills the channel. Downcutting is the opposite process, where the stream cuts downward into the bed, while degradation is the overall lowering of the landscape due to geological processes. Saltation is a type of transport where sediment is bounced along the bed of the stream, but it is not descriptive of the process of sediment accumulation.
