Abstract

The elongation of a sand spit on a seabed with different water depths and slopes was numerically simulated using the BG model (a three-dimensional model for predicting beach changes based on Bagnold's concept). The examples of sand spits and a pond enclosed by a barrier were examined first using aerial photographs and bathymetric survey maps. The formation of a sand spit and a barrier was predicted using the BG model under the conditions that the water depths where a sand spit is formed were changed to 5, 10, 15, and 20 cm in a model scale of 1/100, and that the seabed slopes were changed to 1/50, 1/40, 1/30, and 1/20. The difference in the form of a sand spit and a barrier formed under these conditions was explained and compared with the natural sand spits and a barrier.
