ABSTRACT

The current review study focuses on a statistical analysis (Meta-analysis) of the most common methods, materials, software, and indices used by researchers over the last twenty years to evaluate and quantify the shoreline evolution. Furthermore, this review targets to highlight some critical points through studied literature such as a) the low rate of high-resolution satellite images usage in a subject where the accuracy is prerequisite, b) the effort to derive information from Landsat images in order to take advantage of the 50-years archive and the freely availability c) the impulse of the UAV during the last 5 years as an alternative low cost but high accurate source of data d) the fact that only 50% of the coastal erosion studies are funded. One hundred thirty-eight papers and articles have been analyzed in detail by the authors and all the key points (methods, materials, software, and indices) were sorted for further statistical analysis. This study is not intended to criticize neither the methods nor the results being mentioned in the previous studies but to give the opportunity to the researchers (especially the new ones) to have an overall view of the subject for the last 20 years with just a glimpse.

摘要

当前的综述研究重点在于对过去二十年来研究人员用来评估和量化海岸线演变的最常用方法，材料，软件和指标进行的统计分析（Meta分析）。此外，本次审查旨在通过研究文献突出一些关键点，例如：a）在以精度为先决条件的对象中高分辨率卫星图像的使用率较低，b）努力从Landsat图像中获取信息以获取50年存档的优势和免费提供的资源c）过去5年间无人机的冲动，作为一种低成本但高精度的数据来源d）仅50％的海岸侵蚀研究获得了资助。作者对一百三十八篇论文和文章进行了详细分析，并对所有关键点（方法，材料，软件和索引）进行了分类，以进行进一步的统计分析。这项研究既无意批评既往研究中提到的方法也无结果，而是给研究人员（尤其是新研究人员）提供机会，让他们对过去20年的主题有一个整体的了解。 。
