Emilia-Romagna coast consists of 110 km of low and sandy beaches, which are particularly exposed to coastal erosion. Among different defence projects, the current trend is going towards soft interventions, such as beach nourishment. In 2016, the third intervention of “Security projects through submarine sand nourishment for critical areas of the regional coastline” was completed. This paper concerns the analysis of the eight coastal stretches involved by this project. A Monitoring Plan for the years 2017 and 2018 has been arranged to evaluate the evolution of each beach and the intervention effectiveness. Morphological variations in terms of shoreline, height, beach profiles and accumulated or eroded volumes have been evaluated by comparing surveys performed on each beach at different times. In the specific case of this project, the presence of a new geodetic infrastructure along Emilia-Romagna coast, the Coastal Geodetic Network (RGC), ensured advantages to surveys’ realization. All the observed results show good evolutions from a general point of view, even if it is difficult to deduce a single trend for the eight beaches. On the other hand, the increasing availability and spatial coverage of data from monitoring surveys could provide powerful instruments for coastal studies. This paper confirms monitoring activities as an efficient way to evaluate beaches’ morphological changes and coastal defence intervention effectiveness.

艾米利亚—罗马涅海岸沿岸海底沙的第三海滩营养项目：地理方法和第一监测结果

艾米利亚—罗马涅（Emilia-Romagna）海岸由110公里的低滩和沙滩组成，尤其容易受到海岸侵蚀。在不同的国防项目中，当前的趋势是朝着软干预，例如海滩营养。2016年，完成了第三项“通过海底沙营养为区域海岸线关键地区开展安全项目”的干预措施。本文涉及该项目涉及的八个沿海地区的分析。已经制定了2017年和2018年的监测计划，以评估每个海滩的演变情况和干预效果。通过比较不同时间在每个海滩上进行的调查，评估了海岸线，高度，海滩轮廓以及累积或侵蚀量方面的形态变化。在此项目的特定情况下，沿艾米利亚—罗马涅（Emilia-Romagna）海岸的新大地测量基础设施，沿海大地测量网络（RGC）的存在，为实现测量提供了优势。从总体上看，所有观察到的结果均显示出良好的演变，即使很难推断出八个海滩的单一趋势。另一方面，监测调查数据的可用性和空间覆盖率不断提高，可以为沿海研究提供有力工具。本文确定了监测活动是评估海滩形态变化和海岸防御干预效果的有效方法。即使很难推断出八个海滩的单一趋势。另一方面，监测调查数据的可用性和空间覆盖率不断提高，可以为沿海研究提供有力工具。本文确认了监视活动是评估海滩形态变化和海岸防御干预效果的有效方法。即使很难推断出八个海滩的单一趋势。另一方面，监测调查数据的可用性和空间覆盖率不断提高，可以为沿海研究提供有力工具。本文确认了监视活动是评估海滩形态变化和海岸防御干预效果的有效方法。
