Dramatic pictures of the almighty force of China's Yellow River as it charges over Hukou Waterfall

The almighty force generated by China's Yellow River during the rainy season causes this stepped section, known as Hukou waterfall, to transform into a raging cascade.
Normally, residents in China's Shanxi Province prepare for the anticipated devastation caused by the flood water from late June/early July. And the high water level remains fast-flowing and turbulent until October.
This year, however, the floods have arrived early, as these dramatic pictures taken yesterday illustrate.

At its maximum, the river's average discharge is said to be 25,000 cubic meters per second. From the sheer ferocity of the water in these shots, it's almost impossible to imagine that further along, the river often runs dry before it reaches the sea.

The low volume is due to increased agricultural irrigation and since 1999 the water has been diverted from the river to serve more than 140 million people and irrigate 48,572 square miles  of land.
 

The high water levels will come as some relief to many regions that border the river's path, however, since millions of people have been suffering from a drought in many parts of the eastern country.

The Yellow River originates in the Bayan Har Mountains and the Anemaqen Mountains and empties into the Bohai Sea drain into the Hai River.

It is also difficult to imagine from these pictures that at the early sections of the river the water runs crystal clear, flowing steadily and forming mirror-like lakes, including Lake Zhaling and Lake Eling, at the foot of the mountains.

Subsequently, the Mongolian name for the river in this section is the Black River.

However, further downstream, the epithet 'Yellow' River earns its name, as it collects rich silt  containing golden-coloured minerals.

By the time the water reaches the Hukou waterfall, Linfen, Shanxi Province (pictured), the water  has collected tonnes of fine-grained loess, a mineral-rich silt that has been deposited on the land having been carried in the wind.

The tiny particles, carried by the river from the Loess Plateau, are continuously deposited along the bottom of its channel, causing natural dams to slowly accrue.

These subaqueous dams, which are unpredictable and generally undetectable, eventually burst releasing enormous rushes of water which course along new flood planes to the sea.
