Young rivers, characterized by high velocity and steep gradients, primarily perform vertical erosion, which results in the formation of V-shaped valleys.

The soil in the delta regions are Alluvial soil.

Largest delta in India is Sunderban delta.

In the upper course of a river gradients are steep and river channels are narrow. Vertical erosion is greatest in the upper course of a river. As the result of this typical features include steep valley sides, interlocking spurs, rapids, gorges and waterfalls.

The Ganges-Brahmaputra delta (the Sundarbans delta) is the largest delta in the world.

Afforestation in catchment areas reduces surface runoff, increases water infiltration into the soil, and prevents soil erosion, thereby conserving both water and soil.

A larger volume of water increases the river's capacity to carry sediment (transportation) and its ability to wear away the riverbed (erosion).

Khartoum State is one of the eighteen states of Sudan. The city is located in the heart of Sudan at the confluence of the White Nile and the Blue Nile, where the two rivers unite to form the River Nile. The confluence of the two rivers creates a unique effect. As they join, each river retains its own color which is the White Nile with its bright whiteness and the Blue Nile with its alluvial brown color. These colors are more visible in the flood season.

The erosive power of a river is directly related to its kinetic energy, which is determined by its mass (volume) and the square of its velocity (speed).
