Aggrading Rivers

Aggrading rivers are those that build up their beds over time by depositing more sediment than they erode. This process often occurs when the river's flow slows down, such as during a rise in water level or a decrease in slope, causing sediments like silt, sand, and gravel to settle and accumulate. The result is a raised riverbed, which can create features like new floodplains or terraces. Aggradation is a natural part of a river’s cycle, helping to shape the landscape and often indicating periods of reduced energy in the river’s flow.
