Analysis of historical near shore bathymetric changes of the Red River Delta coastal zone indicates that the wave and current patterms in conjunction with tidal levels primarily control the shoreline retreat in the studied zone. Two sets of models were used to simulate these processes including wave, circulation models. Sediment transport and morphology change models. The first set of models consists of the regional wave model SWAN for the whole East Sea and the local wave model STWAVE. Analogously, the circulation simulations start from ADCIRC (regional model for the west coastal zone of the Gulf of Tonkin) and then proceed with the local model CMS-M2D. In general significant changes in the tidal level for the Red River Delta, two local models are coupled with one hour time step within the surface modeling system (SMS) using the "Steering modul ". The morphology change model employs the LUND-CIRP sediment transport formulas with the wave and current inputs from two previously mentioned local mudels. Model's validation was done using data collected during the field surveys of the VS/RDE-03 project in the frame of Vietnam Sweden Research Program. Based on the wave and tide computations for the deep sea zone and average seasonal discharge of Red river at Balat mouth. computational scenarios have been determined using the concept of morphological wave height and morphological tide level for computation of the coastline changes.
