The mechanism of morphology change at the first (western) entrance of lake Saroma were investigated with the 20 years bathymetric survey data set. It shows that the volume around the entrance decreased after the east jetty construction started and the major morphology changes were erosion along the channel and movement of ebb shoal. A numerical model which aimed to predict the morphology change for several years was developed based on the sediment transport characteristics. The simulation result shows that this model can quantitatively reconstruct the observed morphological changes for 3-4 years.
