Study of dynamic mechanism for the formation and growth of gullylandform on the subaqueous delta near old Huanghe River mouth

  • Based on the features of gully landform on the subaqueous delta near old Huanghe River mouth, a dynamical method to analyse mechanism for the growth of gully was used. It is shown that wave-induced near bed current is the dominant factor which leads to growth of gully. Secondary current caused by turbulent fluctuation in the gully makes velocity field very complicated. And boundary shear stress caused by them has an important effect on erosion of gully, and suspension and dispersion of sediment. The pattern of gully's lateral profile is related intimatey to the velocity field of main and secondary current.
