Question

Quizplus · Accepted Answer

Downcutting streams are characterized by steep gradients, high velocities, and turbulent flow, resulting in rapids and lots of whitewater. This is typical of a youthful stage of valley evolution, where erosion is actively cutting through the landscape. Wide floodplains are associated with mature stage, meandering channels and natural levees with old age, and U-shaped, cross-valley profiles with glaciated landscapes.
