In the present paper, after a sensitivity analysis, the calibration and verification of a novel morphodynamic model have been conducted based on a high-quality field experiment data base. The morphodynamic model includes a general formula to predict longshore transport and associated coastal morphology over short- and long-term time scales. With respect to the majority of the existing one-line models, which address sandy coastline evolution, the proposed General Shoreline beach model (GSb) is suitable for estimation of shoreline change at a coastal mound made of non-cohesive sediment grains/units as sand, gravel, cobbles, shingle and rock. In order to verify the reliability of the GSb model, a comparison between observed and calculated shorelines in the presence of a temporary groyne deployed at a mixed beach has been performed. The results show that GSb gives a good agreement between observations and predictions, well reproducing the coastal evolution.

海岸线演变的预测。混合海滩案例通用模型的可靠性

在本文中，经过敏感性分析后，基于高质量的现场实验数据库对新型动力学模型进行了校准和验证。形态动力学模型包括一个通用公式，用于预测短期和长期时间内的沿岸运输和相关的海岸形态。对于大多数现有的针对沙质海岸线演变的单线模型，建议的通用海岸线海滩模型（GSb）适用于估算由非粘性沉积物颗粒/单位（如沙子）制成的沿海丘陵的海岸线变化，碎石，鹅卵石，木瓦和岩石。为了验证GSb模型的可靠性，已经对在混合海滩上部署临时防波堤的情况下观察到的海岸线和计算出的海岸线进行了比较。
