Depression Systems in Western Planum Boreum, Mars: Distributions, Orientations

Introduction: Planum Boreum, in the north polar region of Mars, forms a domical plateau largely dissected by depression systems of various dimensions (Fig.1). The largest and most deeply incised of these is Chasma Boreale, a unique canyon that divides Planum Boreum into a main lobe and a smaller lobe east of the chasma known as Gemina Lingula. Other widespread depression systems include undulat...

New Elements on Stratigraphy of South Polar Layered Deposits on Promethei Lingula Region and a Possible Structural Approach

Introduction: South Polar Layered Deposits (SPLD) have been analyzed by several authors [1,2,3, 4] in order to describe mayor layers sequences using visible images [1,2,3,4] and sounding radar datasets (Mars Express MARSIS and MRO ShaRAD [1,2]), defining different units. [1] mapped three main SPLD units through several distinctive erosion-resistant marker beds or packets of layers. In particula...

A Numerical Investigation on Aerodynamic Coefficients of Solar Troughs Considering Terrain Effects and Vortex Shedding

Recently, increase in the cost of fossil fuels and taking into consideration the environmental effects of exploiting them, caused many researchers and governments to find some ways to make use of renewable energies more cost-effectively. Solar energy is a category of renewable energies which could be harvested via several technologies. One of the most practical methods is using parabolic trough...

Spatial and temporal variations of glacial erosion in the Rhône valley (Swiss Alps): Insights from numerical modeling

The present-day topography of the European Alps shows evidence of intense glacial reshaping. However, significant questions regarding Alpine landscape evolution during glaciations still persist. In this study, we focus on the Rhône valley (Swiss Alps), and use a numerical model to estimate patterns and magnitudes of glacial erosion. Comparing modeling results on a reconstructed pre-glacial topo...

A model for spiral flows in basal ice and the formation of subglacial flutes based on a Reiner-Rivlin rheology for glacial ice

Flutes are elongated sediment ridges formed at the base of glaciers and ice sheets. In this paper, we show that flutes can be the product of a corkscrew-like spiral flow in basal ice that removes sediment from troughs between flutes and deposits it at their crests, as first suggested by Shaw and Freschauf. In order to generate the type of basal ice flow required for this mechanism, the viscous ...
