EOLIAN PROCESSES AND LANDFORMS aeolus: Greek god of the wind aeolians: a Greek tribe aeolian harp: produces music as air passes over the strings wind is an important geomorphic agent in arid environments and in other smaller areas where fine sediments are exposed to wind, i.e. where surface cover is lacking: beaches , floodplains, deserts , soil disturbed by agriculture otherwise wind is not an important geomorphic agent due to its low density relative to rock: 1/2000 as opposed to 1/1.6 for water/rock given the buoyant force of water, little energy is required to keep sediment suspended, whereas in air only the finest sediments (dust) remain in suspension Controls on wind erosion 1. wind velocity o E = V 3 rho, where E is erosivity , V is velocity and rho is air density o thus the erosivity of wind is an exponential function of wind velocity, i.e . if the wind velocity doubles, the wind is 8X more erodible or, if it triples, the wind is 27 times more erodible o
