Rivers begin high up in the mountains so they flow quickly downhill eroding the landscape vertically. The river cuts a deep notch down into the landscape using hydraulic action, when the sheer force of the water gets into small cracks and breaks down the sides of the river valley
The rocks which have fallen into the river assist the process of corrasion and this leads to further erosion. The river transports the rocks downstream and the channel becomes wider and deeper creating a V-shaped valley between interlocking spurs.
