What is the main function of a river in its upper course?

उत्तर
In the upper course of a river, the main function is erosion. The river flows swiftly due to the steep gradient, and it primarily erodes its bed and banks. This erosion action leads to the formation of various landforms like V-shaped valleys, waterfalls, and gorges. The dominant process is the downward cutting of the riverbed.
