On their arrival, the Swedish monarchs were greeted by Olle Burrell and Karin Gardes from the Stockholm International Water Institute.

During the ceremony, King Carl Gustaf, the official patron of the prize, presented the Stockholm Water Prize to Italian hydrologist Dr Andrea Rinaldo.

The prize, often described as the Nobel Prize for Water, is the world’s most prestigious water prize. Dating back to 1991, it celebrates those who have achieved remarkable achievements in the aquatic field.

Last night, the daughter of the Swedish king and queen, Crown Princess Victoria, cut an elegant figure in a floral dress while attending a sustainability award ceremony in Stockholm.

The mother-of-two, 46, looked stunning in the sophisticated patterned ensemble as she stepped out at the Junior Water Prize, a ceremony for young people interested in water and environmental issues.

Victoria’s standout dress consisted of a navy blue billowing skirt with floral detailing and a black top with a square neckline.

Keeping her makeup simple kept the royal looking fresh, making her dress the main attraction.

Crown Princess Victoria is the patron of the Stockholm Junior Water Prize, which is open to entrants from around the world.

Each year, some 30,000 young people participate in hopes of taking home the $15,000 prize money, along with a blue crystal sculpture, a diploma and a place to stay in Stockholm.

They compete in national competitions in the hope of getting the chance to represent their country in the international final held during World Water Week in Stockholm.

The national and international competitions are open to young people between the ages of 15 and 20 who have carried out water-related projects with proven environmental, scientific, social or technological significance. The projects range from local or regional to national or global topics.
