Rivers are frequently shown as peaceful watercourses going through forests, valleys, and cities. However, some rivers flow with great force, their velocity being influenced steep ground, heavy rainfalls, narrow channels, strong rapids, and sudden changes in altitude.
What makes the fastest rivers in the world interesting is not merely their speed but also the way in which water can dramatically alter the landscape.
The Congo River
The Congo River is one of Africa’s most remarkable rivers. In the area near its lower section it goes through deep gorges and narrow channels which produce strong currents and numerous rapids.
