Abstract:Based on historical records and in situ data,this paper first draws the conclusion of seabed erosion in the Chengdao area near the Yellow River mouth,then numerically studies the tidal field and suspended sediment transportation around the area. Using Galerkin finite element method and Bagnold sediment transport formula,this paper computes the seabed erosion in 1976,1988 and 1994 recpectively.The numerical results show good agreement with measured data with an error of 15%.
Keywords:seabed erosion  numerical modeling  Chengdao area
