Abstract:   (5095 Views)

 This  investigation, have  hydropolitic significant for Aras River that have frequent and more lateral  migration.In this study is used many equation, for example, Ω ،Ự ω, وΈ …. Equation, for estimating of bank erosion and sediment dynamics .Output of  estimating  is analyzing and then maps is produced by using of GIS technique. The results of study suggested  that rate of channel changing is vary in  river course. Wide changes of river course is maximum  at near of Jolfa and Poldasht  ,in other parts is minimum .Wide changing of course is show that lateral migration is high and alluvium is thick and broad .Cut power of river is increased when radial of curves is more .This event is occurred  where that wide changes is high .The results also show that is increased rate of sediment when cut power is increased. Sadly  lateral  migration rate Iran orientation is increased at 30 decade recent. This result show that gradually is decreased area land of Iran . 

Keywords: lateral migration, erosion at border unit, soil erosion, Aras River
