at the source because it's narrow and steep so it has a track which keeps it long and fast
The processes of erosion and deposition create different river landforms. River landscapes change as you go downstream from the source to the mouth. In the upper course of a river, steep gradients lead to rapid-flowing rivers. In the middlecourse, the river meanders through gentle gradients.

Decrease. The source of the river is usually in a mountainous area with a steep gradient.
If a river channel has a steep gradient, the river flows faster and has more erosive energy.
a mature river
the gradient and how much friction there was. The gradient means how steep the land the river is on so if it is very steep them the velocity will be higher.
A river Bore.
why is the upper river with its fast flowing steep valley suitable for animal grazing
Upland river valleys have steep sides because of the erosive power of the river cutting into the surrounding land over time. The river erodes the sides of the valley, creating the steep slopes. Additionally, the geology and underlying rock composition in upland areas can also influence the formation of steep-sided valleys.
A canyon.
Cataracts
