Des photos incroyables d'un nettoyage au sable de la Rivière Jaune

Non, il ne s'agit pas d'images trafiquées à l'aide de Photoshop! Ces superbes photos ont été prises aux abords de la Rivière Jaune, en Chine, durant un nettoyage au sable. Le processus vise à nettoyer le fond de la rivière d'environ 30 millions de tonnes de limon qui se dépose dans son lit.

Selon le média CRI English, ce processus est répété chaque année dans le réservoir Xiaolangdi pour enlever les sédiments. Quand le limon s'accumule, le niveau de la rivière augmente, mettant en danger les digues.

Le nettoyage se fait grâce à un puissant jet de sable de 91 820 pieds cubes par seconde.

  • Grand Prize: The Explosion!

    "The subject's name is Busaba, a well cared for Indochinese Tigress whose home is at Khao Kheow Open Zoo, Thailand. I had taken many portraits of Busaba previously and it was becoming more and more difficult to come up with an image that appeared any different to the others. Which is why I took to observing her more carefully during my visits in the hope of capturing something of a behavioral shot. The opportunity finally presented itself while watching Busaba enjoying her private pool then shaking herself dry. In all humility I have to say that Mother Nature smiled favorably on me that day!" <a href="http://ngm.nationalgeographic.com/ngm/photo-contest/">2012 National Geographic Photography Contest</a>

He allegedly said that the attempt to cross Hardangervidda was just as dangerous and hard as the conquering of the South Pole. The group in the picture used the race as preparations for an attempt to cross Greenland." <a href="http://ngm.nationalgeographic.com/ngm/photo-contest/">2012 National Geographic Photography Contest</a>
