Starting from the second half of the twentieth century, the Ionian coast of the Basilicata Region (southern Italy) has shown a progressive retreat. The analysis of the shoreline variations covering a time lapse of about 150 years has been carried out over the last 20 years according with the evolution of technology over time, so using various data sources and methods, as historical cartography, aerial and high-resolution (HR) satellites images, and Global Position System (GPS) surveys. The results of the analyses have proven to be helpful in describing the coastal dynamics, driven by several factors, natural or human induced, with their own intensity and frequency or persistency. In the case of Basilicata Ionian coast, the main reason of the progressive retreat is found in the huge sedimentary budget deficit, coming from the repeated damming of four of the five rivers flowing towards the sea in the Ionian coastal stretch. Moreover, the long observation period allows reading the punctual response of the coastal environment to the severe human induced variations either in the catchment areas of the rivers, or at coastal works along an already stressed coastline.

巴斯利卡塔爱奥尼亚海沿岸的动力学：人类和自然驱动力

从二十世纪下半叶开始，巴西利卡塔地区（意大利南部）的爱奥尼亚海沿岸地区逐渐退缩。在过去的20年中，随着技术的不断发展，已经进行了大约150年的海岸线变化分析，因此使用了各种数据源和方法，例如历史制图，空中和高分辨率（ HR）卫星图像和全球定位系统（GPS）调查。分析的结果已被证明有助于描述由自然或人为因素等几种因素驱动的沿海动态及其自身的强度，频率或持久性。在巴斯利卡塔爱奥尼亚海沿岸，逐渐退缩的主要原因是巨大的沉积预算赤字，来自在爱奥尼亚海沿岸流向大海的5条河流中的4条河流的反复筑坝。此外，漫长的观察期使人们可以读取沿海环境对河流集水区或已经紧张的海岸线沿岸工程造成的人为严重变化的准时响应。
