деградација

деградација

In geology, refers to the lowering of a fluvial surface, such as a stream bed or floodplain, through erosional processes. It is the opposite of aggradation. Degradation is characteristic of channel networks in which either bedrock erosion is taking place, or in systems that are sediment-starved and are therefore entraining more material than is being deposited.
