Aeolian Geomorphology
Conveners: Vanda Sales, António Campar, Ana Ramos-Pereira, Amadou Abou Sy

Aeolian processes are related to the wind´s ability to shape the surface of the Earth or other planets. The wind erodes (by the means of deflation or abrasion), transports (in the form of suspension, saltation, or creeping) and deposits material in the surface, as well as sculpts rocks and pre-existing deposits. These processes create shapes of different types, which results in a very specific kind of landscape. Aeolian landforms hold clues to past as well as to present climate because they preserve structures resulting from different wind directions with variable wind intensities. The wind is an effective agent in regions with sparse vegetation, a lack of soil moisture and a large supply of unconsolidated sediments. Therefore, Aeolian features are common in deserts, beaches, and fluvial plains of semi-arid areas on Earth, as well as in other appropriate environments of other planets of the Solar system. Aeolian processes and landforms are studied, analyzed, and mapped from the use of many different tools and equipment, and represent one of the most important branches of geomorphology.
