Aggradation vs. Degradation: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 27, 2023
Aggradation is the process of building up land by sediment accumulation, whereas degradation involves the breakdown or erosion of land and materials.

Key Differences

Aggradation refers to the geological process where sediment is deposited, building up land or river beds, contrasting with degradation, which is the process of wearing down or eroding land and materials.

In river systems, aggradation can occur when the water's carrying capacity decreases, leading to sediment deposition, whereas degradation in rivers involves the erosion and deepening of river beds.

Aggradation often results from natural processes such as flooding, which deposits sediment, while degradation can result from both natural processes like weathering and human activities such as deforestation.

Aggradation can lead to the formation of new landforms, such as deltas or alluvial fans, whereas degradation often results in loss of soil fertility, landscape changes, and environmental degradation.
