Eolian Deposit a deposit that forms as a result of the accumulation of wind-driven products of the weathering of solid bedrock or unconsolidated alluvial, lacustrine, marine, or other deposits. Transport both along and across the shore is critical to the maintenance of the sand budget and consequently to the landforms and habitat on which sandy-shore organisms depend (Clark 1983). Aeolian sand fluxes, particle pathways, pattern of erosion and deposition are important issues for the understanding and prediction of the aeolian landforms evolution. Aeolian landforms and sediments on the S2 surface are restricted to elevations above 166 m, a conclusion that supports earlier findings (Morris and Pierce, 1967).

The course illustrate landforms associated with endogenous and exogenous processes starting from structural and volcanic landforms. This paper aims to provide a global classification, establish what interaction types exist and how common they are. To detect the spatial characteristics of coastal landforms in a section of the Nile Delta region (Egypt) between 1984 and 2006, multitemporal satellite imagery was examined. Sedimentology 51 (5), 1103-1125. , 2004. All particles transported by wind are ultimately dropped under two conditions – one, if the velocity of wind drops; or two, if the wind meets an obstacle in its path. Topography fundamentally influences the distribution and morphology of aeolian landforms via the modification of surface wind flow and the creation of space for sediment deposition. However, an aeolian imprint is not only seen in landforms of aeolian origin such as dunes and coversands, but is widely known from sediments formed in a number of settings, e.g., fluvial (Zhang et al., 2015; Zieliński et al., 2015), lacustrine (An et al., 2012) and glacial environments (Kalińska-Nartiša & (A detailed classification of aggradational and deflational-aggradational landforms that are dependent on wind regime are given in DUNES and BARCHANS.
