由Salinas-El Espartal海滩/沙丘系统组成的封闭屏障构成了阿斯图里亚斯(西班牙西北部)中部海岸avil<s:1>河口综合体的一部分。在本研究中,基于对自然和人为过程的评价,建立了海滩及其沙丘场以及河口的演变。特别是,在河口进行疏浚对该系统产生了强烈的负面影响,包括沙丘前缘退缩了20至30米,海滨退化,1965年首次在海滩沙丘边缘建造,1994年重建。相比之下,在附近的海滩(Xagó)倾倒疏浚的材料,造成了平均45米的显著沙丘推进,形成了风成表格。未来对阿维尔萨梅斯河口的疏浚管理应与埃斯帕塔尔和Xagó沙丘场的演变直接相关。
The confining barrier comprising the Salinas-El Espartal beach/dune system forms part of the mouth complex of the Avilés estuary on the central coast of Asturias (NW Spain). In this study the evolution of the beach and its dune field, as well as the estuary, is established based on appraisal of both natural and anthropogenic processes. In particular, dredging in the estuary mouth has had a strong negative impact on the system, including the recession of the dune front by between 20 and 30 m, and degradation of the seafront, first built at the edge of the beach dunes in 1965 and rebuilt in 1994. By contrast, the dumping of dredged material at a nearby beach, Xagó, has caused a remarkable dune progradation of 45 m on average, creating aeolian tabular sheets. The future dredging management of the mouth of the Avilés estuary should be directly related to the evolution of the El Espartal and Xagó dune fields.
