摘要：As we know, deby relation with water currentvelocity is a direct one.Type of rout in water canal and stresses on its current may cause eddy and torque for the current.There are some forcings and stresses dominating variations,phenomena, waves and currents on rivers, seas and other waterbasins.Sedimentations and coastal destruction are effectsca used by debies of water and sediment particles in water canal(for rivers).Surface patterns are different in various waterbasins.Of course wind is an important stress affecting on surface pattern which we have not considered in this researchbecause of river.In this research, two current patterns would bestudied in direct and indirect canal located in a river.In fact inthis paper, the importance of centrifugal force in a meander of ariver could be evaluated in comparison with its not being existIn regards to damages for coastal zone, particularly.
