Abstract

A two-dimensional simulation on tidal flow and sediment was conducted on three schemes of 300 000DWT channel extension projects,two with breakwaters and one without breakwater,in Lianyungang Port.The influences of the projects on channel siltation are compared and analyzed based on the calculation of siltation using Dou Guoren's non-equilibrium suspended-sediment transport equation and riverbed deformation equation,during normal weather and typhoon season.The results show that the first project with breakwaters has better abilities in wave protection and sand prevention than the other two,and its layout of breakwaters is more rational.
