SAND DRIFT POTENTIAL IN EL-KHANKA AREA, EGYPT

摘要: Wind erosion force vectors were computed from data of frequencyof occurrence windspeed and direction based on the assumptionthat wind is proportional to (windspeed)3× duration exposure.The vertical distribution eroded soil material wasmathematically described. The transition height betweensaltation suspension could be identified used tointegrate two equations describing saltation suspension.The avalanching process was studied by evaluating horizontal changes material. andhorizontal constituents, i.e.,particle size distribution, mean weight diameters, plantnutrients heavy minerals content for selected stormswere also evaluated. Results revealed that constituents change considerably with downwind distance.To assess in properties due erosion,surface samples taken original surfaceand freshly accumulated drifts near field.Enrichment ratios more than one fine fraction, organic matter, moisture retention, chemical constituentsindicating a loss their contents field.
