Key Terms - Aggradation & Degradation
This image shows aggrading sediment in the channel center.
- The process by which a Stream's gradient steepens due to increased Deposition of sediment
- The process by which a Stream's gradient becomes less steep, due to the Erosion of sediment from the Stream bed
- Generally follows a sharp reduction in the amount of sediment entering the Stream
