Shoreline change in and around the Thubon river mouth, Central Vietnam

Abstract

Application of GENESIS model (GENEralized model for Simulating Shoreline change) for studying the shoreline change in and around the Thubon River mouth, Central Vietnam is presented. The input parameters used are the near shore wave height, wave period and wave direction, initial shoreline positions and sediment grain size. The near shore wave parameters were estimated using SWAN model. The change in shoreline during 1997 to 1998 was estimated and compared. In general the computed shoreline positions show good agreement with measured ones, except the shoreline sections in the area of river mouth, which lives in the model boundaries and in the current dominated regions. Obtained model results give a better understanding on the changing behaviour of the shoreline of the study area.
