el for the coastal zone of the Red River delta area in Vietnam was presented. The development code was COHERENS V2.0, a three-dimensional hydrodynamic multi-purpose model for coastal and shelf seas based on the finite element method. The results of the model with 10 scenarios simulations show the role of wind condition combined with tidal os...
