In their early stages, river valleys are characterized by V-shaped cross sections. This is because the river has not yet eroded deeply into the valley and is still actively cutting downwards. As the river continues to erode the valley over time, the cross section will eventually become wider and more U-shaped. Water tables and moraines are not characteristic of early stage river valleys.
