Inside of the dunes we find shade.

The interior contains two groups of dune fields.

There's hundreds, up to a 1,000 or 1,200 miles of dunes.

Ellen was often spotted on the beach in the solitude of the dunes.

Although other landers in other places on Mars have seen many ripples and dunes, no ripples or dunes are visible in the area of Phoenix.

The average precipitation in the Chilean region of Antofagasta is just per year.

It adds roughness to the dune's surface, to the texture of the dune's surface, binding the grains.

If you want to stop a sand dune from moving, what you need to make sure to do is to stop the grains from avalanching over its crest.

In the southwestern part of the country, loss of groundcover was encouraging wind erosion and sand dune formation.

It provides a physical support structure for the trees, and it creates physical spaces, habitable spaces inside of the sand dunes.

Other activities are taking place in areas such as sand dune fixation, forest management and the promotion of agroforestry.

So, we have a way of turning sand into sandstone, and then creating these habitable spaces inside of the desert dunes.

This process accelerated in 1904 when a lime sand brick factory was built just south of Hillegom, which needed large amounts of sand.

Windbreaks have been planted to protect agricultural lands and tens of thousands of moving sand dunes have been stabilized with the use of oil products and by planting trees.

The Asian TPN 3 on rangeland management in arid areas, including the fixation of shifting sand dunes, was launched in 2001.

According to the reports, soil conservation continues to be given high priority by the organizations in their efforts to preserve the environment, alongside sand dune fixation strategies.

The Israeli army has buried rubble in sites risking pollution, especially in sand dune areas, which are natural infiltration for the Gaza aquifer.50

The extent of sand dunes has fallen by 40 this century, mainly in along the western shores of Europe a third of the loss has occurred since mid 1970s.

Unique provisions in the Kwanlin Dün First Nation Final Agreement include the commitment to establish two Special Management Areas Kusawa Park, and Lewes Marsh Wetland Habitat Protection Area.

And they can use that energy in case the wind falls away, and the tide is coming up, and there is still a little bit of energy to reach the dunes and save their lives, because they are drowned very easily.

Under these agreements, the Kwanlin Dün First Nation will retain approximately 1,040 square kilometres of land as settlement lands, including 35 square kilometres within the City of Whitehorse.

In collaboration with Columbia University, Ben Gurion University had also designed interferometric radars to monitor dune and sand migration and evaluate the aftermath of the Indian Ocean tsunami and the quality of water in the Red Sea.

For those tests, the brothers trekked four miles (6 km) south to the Kill Devil Hills, a group of sand dunes up to high (where they made camp in each of the next three years).

Kwanlin Dün First Nation will have a role in the management of these areas, as well as specific rights for fish and wildlife harvesting, and economic and employment opportunities.

So, the wings pump up air in lemonade bottles, which are on top of that. And they can use that energy in case the wind falls away, and the tide is coming up, and there is still a little bit of energy to reach the dunes and save their lives, because they are drowned very easily.
