Arid geomorphology - a scientific direction proposed and developed by the author. The region of investigation in this field - sublatitudinal Afro-Asian arid belt, which has geographical (temperate zone of the north-eastern quarter sphere), tectonic (Mediterranean Alpine belt), morphostructural (platforms, young platforms, microplates), landscape-climatic (deserts, semideserts, steppes), geomorphologic (large plains), and historic-civilization (centers of the main ancient civilizations) unity. Arid plain relief is the subject of investigation; the end of the Late Pleistocene, Holocene, and contemporaneity constitute its time limits. The objectives of arid geomorphology are learning the eolean geomorphic systems - the relief of adjacent deflation and accumulation plains developing in unity, reconstruction of relief evolution in the arid plain regions, and using certain geomorphologic situations and scenarios of evolution for forecasting their possible recurrence in the future.
