The complexity of the foredune system is responsible for its morphological diversity and different development scenarios. On wave-dominated coasts, wave activity that permanently changes foredune and beach morphometry is the main limiting factor of foredune development. Based on a field data collected on the Curonian Spit in 2002–2017, the dynamic pattern of the cross-shore profile parameters was determined. There is a close correlation between the foredune height and horizontal distance between the shoreline and foredune top. In foredunes with differing morphology and sedimentology, the established ratio between these indices is rather stable and makes 0.14–0.21 (an average of 0.17). During accretion-dominated periods, with minimal storm surge impact on the foredune, the slope flattens and, under ideal conditions the foredune toe approaches the shoreline, and the stoss slope angle reaches 0.17 (i.e. ∼10°).

foredune系统的复杂性是其形态多样性和不同开发场景的原因。在以波浪为主的海岸上，永久改变龟足和海滩形态的波浪活动是龟足发展的主要限制因素。根据2002-2017年在库尔斯沙嘴上收集的现场数据，确定了跨岸剖面参数的动态模式。前缘高度与海岸线和前缘顶部之间的水平距离之间存在密切相关。在形态和沉积学不同的古迹中，这些指标之间的既定比率相当稳定，为0.14-0.21（平均值为0.17）。在增生为主的时期，风暴潮对山丘的影响最小，斜坡变平，
