Nourished Beach(滋养海滩)研究综述
Nourished Beach 滋养海滩 - In particular, scarp generation is often observed at nourished beaches or under the incidence of oblique storm waves; scarps can pose severe risks to beach users and negatively impact local ecosystems. [1] Experimental and numerical simulation of cross-shore morphological processes in a nourished beach. [2] Approximately 14% of the placed sand in the water depth less than 2 m was lost after one year, as may be expected for nourished beaches. [3] A series of 21 beach profiles were collected from August 2017 to July 2018 to monitor the morphological changes of the nourished beach. [4] In this study, the morphological evolution of beach scarps was examined at a nourished beach in a low-energy and micro-tidal environment. [5] Located closer to the break point, the nourishment induces an earlier wave breaking, which dissipates part of the wave energy (lee effect), leading to a negative sediment flux perturbation around this break point and a positive sediment flux perturbation around the break point of the un-nourished beach. [6] We synthesize existing findings on biogeochemical processes at source areas and renourished beaches before, during, and after nourishment activities, and identify gaps in knowledge. [7] beach durability, sediment loss rate) which could not fully reflect the actual performance of a nourished beach. [8] Morphodynamic evolution and adaptability of nourished beaches. [9] In this study, a physics-based 3D morphology model for the estimation of an erosion rate of nourished beach is newly proposed. [10]特别是，在营养丰富的海滩或倾斜风暴波的发生下，经常观察到陡坡的产生；陡坡会给海滩使用者带来严重风险，并对当地生态系统产生负面影响。 [1] 营养海滩跨岸形态过程的实验和数值模拟。 [2] 一年后，在水深小于 2 m 的沙子中，大约 14% 的沙子流失了，这对于营养丰富的海滩可能是预期的。 [3] 从 2017 年 8 月到 2018 年 7 月，收集了一系列 21 个海滩剖面，以监测营养海滩的形态变化。 [4] 在这项研究中，在低能量和微潮环境中的营养海滩上检查了海滩陡坡的形态演变。 [5] 靠近断裂点的营养物质会引起较早的波浪破碎，这会消散部分波浪能（李效应），导致该断裂点周围的沉积物通量为负扰动，而断裂点周围的沉积物通量为正扰动。营养不良的海滩。 [6] 我们综合了在营养活动之前、期间和之后在源区和补充营养海滩的生物地球化学过程的现有发现，并确定了知识差距。 [7] 海滩耐久性、泥沙流失率），不能完全反映营养海滩的实际表现。 [8] 营养海滩的形态动力学演变和适应性。 [9] 在这项研究中，新提出了一种基于物理的 3D 形态模型，用于估计营养海滩的侵蚀率。 [10]
