Question

Quizplus · Accepted Answer

A stream that shows a delicate balance among gradient, discharge, flow velocity, channel shape, and sediment load is said to be "graded." This means that its equilibrium profile has been established, and its characteristics all work together to maintain a steady state. A superposed stream is one that has eroded through different rock layers to create a new channel, while an incised stream is one that has cut deeply into its bed. A divided stream usually refers to a river that splits into two or more channels.
