在一个广泛的实地工作和物理模型研究方案中，已经对剖面性能和引起卵石障壁海滩漫顶和过冲的条件进行了研究。赫斯特嘴，在英国南部海岸的水力性能进行了详细的研究，并已被用来设计一个管理方案，这个障碍海滩。这包括设计一个海滩补给计划和量化的漫顶阈值和报警条件，为一系列的海滩的几何形状。一系列广泛的三维物理模型试验进行了讨论，并提出了一个无量纲的参数框架，它提供了一种方法，估计的条件下，将导致波峰积累，突破和波峰降低的卵石障壁海滩，广泛的海滩的几何形状。
The profile performance and the conditions giving rise to overtopping and overwashing of shingle barrier beaches have been examined in an extensive programme of field work and physical model studies. The hydraulic performance of Hurst Spit, on the south coast of the UK, has been examined in detail, and the studies have been used to design a management programme for this barrier beach. This has included the design of a beach replenishment scheme and quantification of overtopping thresholds and alarm conditions, for a range of beach geometries. An extensive series of 3-dimensional physical model tests are discussed and a dimensionless parametric framework is suggested, which provides a method of estimating the conditions that will result in crest accumulation, breaching and crest lowering of shingle barrier beaches, for a wide range of beach geometries.
