A graded stream is a stream that has reached a state of equilibrium where the processes of erosion and deposition are in balance. This means that the stream channel is neither degrading (eroding) nor aggrading (depositing sediment), but instead is maintaining a constant profile and shape over time. Graded streams typically have a smooth, gently sloping channel with a low gradient, which allows for efficient transport of sediment without excessive erosion or deposition. Meandering streams can also be graded streams, as they maintain a balance between erosion on the outer banks of meanders and deposition on the inner banks.
