对区域海岸演变模式Cascade进行了改进，以更好地描述沉积物的迁移和储存。重点是从陆上到水下部分的海滩和沿海入口浅滩演变的跨海岸交换材料。跨海岸物质交换现在包括由于波浪冲击和过冲造成的侵蚀，以及风造成的屏障和沙丘堆积。级联验证数据集从大洋城，马里兰州，屏障岛的长期响应，这些类型的跨海岸交换。入口浅滩的子模型现在包括以前未用Cascade描述的洪水浅滩，并且通过解析表达式获得指定入口形态元素之间的材料转移的所有耦合系数。利用来自纽约长岛南海岸的数据评估了Cascade模拟进口浅滩演变的能力。预测产生了稳健和可靠的结果，但需要进一步测试，以确定模型中所需的经验系数值。（减）
he regional coastal evolution model Cascade was enhanced to better describe the transfer and storage of sediment. Focus was on the cross-shore exchange of material from the subaerial to the sub-aqueous portion of the beach and on shoal evolution at coastal inlets. Cross-shore material exchange now includes erosion due to wave impact and overwash, and barrier and dune build-up by wind. Cascade was validated with a data set from Ocean City, Maryland, for the long-term response of a barrier island to these types of cross-shore exchange. The sub-model of the inlet shoals now includes the flood shoal, which previously has not been described by Cascade, and all coupling coefficients specifying the transfer of material between the inlet morphological elements were obtained through analytical expressions. The capability of Cascade to simulate inlet shoal evolution was evaluated with data from the south shore of Long Island, New York. Predictions have yielded robust and reliable results, although further testing is required to determine empirical coefficient values needed in the model. (Less)
