A stream that has attained a state of equilibrium, or balance, between erosion and deposition, so that the velocity of the water is just great enough to transport the sediment load supplied from the drainage basin, and neither erosion nor deposition occurs.
A stream whose smooth longitudinal profile is unbroken by resistant ledges, lakes, or waterfalls and that exactly maintains the slope, velocity, and discharge required to carry its sediment load in equilibrium without erosion or sedimentation.
A stream maintaining an equilibrium between the processes of erosion and deposition, and therefore between aggradation and degradation.
Conceptual hypothesis that a stream's form and dynamics have evolved to the point where their slope, discharge, and sediment transport capabilities are in equilibrium such that the stream can transport all of the sediment delivered to it by weathering or erosion of the adjacent valley slopes
A stream whose smooth profile is unbroken by resistant ledges, lakes, or waterfalls, and which maintains exactly the velocity required to carry the sediment provided to it.
A condition when a stream's bed is neither aggrading (sediment and/or gravel deposition is raising the bed) nor degrading (sediment and/or gravel erosion is lowering the bed). The stream is considered to be in equilibrium.
A stream that is maintaining a balance between the processes of erosion and deposition.
