采用 Serizawa 等人提出的改进 BG 模型，研究了在海岸线方向突然变化的海岸上平坦的浅海海底伸长的沙嘴和陡坡上的尖状前陆的形成。 （2009a）。 Uda 和 Yamamoto (1992) 的实验结果验证了计算结果。结果表明，案例1中，细长的沙嘴沿着浅海和近海陡坡之间的边缘线延伸，而案例2中，由于陡坡上的沙子沉积而形成了尖状前陆。预测和实测的沙嘴和尖状前陆的地形吻合良好。
The formation of a sand spit elongating on a flat shallow seabed and a cuspate foreland on a steep slope on coasts where the direction of the coastline suddenly changes was investigated using an improved BG model proposed by Serizawa et al. (2009a). The calculated results were validated by the experimental results obtained by Uda and Yamamoto (1992). Their results showed that a slender sand spit extends along the marginal line between the shallow sea and offshore steep slope in Case 1, whereas a cuspate foreland is formed owing to the deposition of sand on the steep slope in Case 2. The predicted and measured topographies of the sand spit and cuspate foreland were in good agreement.
