Snow transport over flat, uniformly rough, open terrain, including snow saltation and snow suspension is successfully simulated using CFD and the results are compared to field measurements of snow concentrations for validation.
The term has taken off in the Alps and describes a high altitude version of fell-running over rough ground, and snow at higher altitude.
Dragging Mertz's body in the sleeping bag from the tent, Mawson constructed a rough cairn from snow blocks to cover it, and used two spare beams from the sledge to form a cross, which he placed on the top.
It had to be quick and easy to put up — and take down — in deep snow on rough mountainous terrain, and light enough to be flown there by helicopter.
Cross-country skis work on the same principle, but for deep snow and rough terrain, with fallen trees and boulders, or on steeper inclines, there is no better snow-travel tool than the snowshoe.
One of them, called BigDog, is remarkably agile for a machine and is able to move over rough terrain such as snow and ice.
Alpine ibex tend to live in steep, rough terrain above the snow line.
He was a 1 mile slog through knee-deep snow on rough terrain to the nearest helipad, and with the light quickly fading, he had ended up in the better of two bad choices.
He was a 1.5-kilometre slog through knee-deep snow on rough terrain to the nearest helipad, and with the light quickly fading, he had ended up in the better of two bad choices.
