Abstract—The trend of the recent development of the Anapa bay-bar is considered based on modeling of sediment transport and morphodynamic processes. It is shown that longshore sediment transport does not have a crucial influence on the coastal dynamics. Most coastlines undergo degradation despite accumulation due to unloading of the longshore sediment flux. The probable reason is the relative sea level rise due mainly to tectonic processes. The proposed model of the coastal barrier following the sea level movement explains to a certain extent the observed trends.

阿纳帕湾-巴尔海岸动力学建模

摘要—基于泥沙运移和形态动力学过程的模型，考虑了阿纳帕湾湾近期发展的趋势。结果表明，沿岸沉积物的运输对海岸动力学没有关键影响。尽管由于沿岸沉积物流量的卸载而积累，但大多数海岸线仍在退化。可能的原因是主要由于构造过程引起的相对海平面上升。拟议的海平面运动后的沿海屏障模型在一定程度上解释了观测到的趋势。
