What is the upper current of a river?

The upper current of a river refers to the flow of water in the upper part of a river system. It is the section of the river where the water is flowing in the opposite direction of the main downstream flow. This phenomenon occurs when there is a change in elevation or slope in the river's course, causing the water to move against the force of gravity. The upper current is typically characterized by faster water flow and may contain obstacles such as rocks or rapids.

Please note that the provided information is a general explanation of the concept of upper current in rivers and may not be specific to any particular river or location.
