Question

explain why the river in the upper course devlop typical landforms​

Answer 1

it is due to the sediments it brings from the mountain

Answer 2

Explanation:

The gradient here is steep and the river channel is narrow. Vertical erosion in this highland part of the river helps to create steep-sided V-shaped valleys, interlocking spurs, rapids, waterfalls and gorges. As the river erodes the landscape in the upper course, it winds and bends to avoid areas of hard rock.
