Question

Quizplus · Accepted Answer

Aggradation is the process of progressive sediment accumulation in a stream. This can occur naturally through erosion and transport of sediment or can be human-induced through land use changes and increased erosion. A graded stream refers to a stream that is in equilibrium with its sediment load, where erosion and deposition are balanced. Braided streams have multiple channels that interweave and can also experience aggradation or degradation. Downcutting and degradation refer to the erosion of a stream channel, rather than the accumulation of sediment.
