ABSTRACT

This paper describes the anthropogenic landforms of the alluvial-coastal plain of Rapallo (Eastern Liguria, NW Italy). Since the second half of the nineteenth-century Rapallo experienced a progressive urban sprawl that became particularly intense after the Second World War and severely modified the former landforms. The identification and mapping of morphological changes was performed through a multi-temporal comparison of historical and recent maps and aerial photographs, an analysis of geo-thematic maps and urban planning documents, an interpretation of stratigraphic data from boreholes, and a field survey activity. The main anthropogenic interventions that shaped the urban landscape of Rapallo were riverbed diversions and channelization, excavations, fillings, and embankments construction along the shoreline. These elements highlight the relevant extent of the human imprint on the pristine environment. Furthermore, the identified anthropogenic geomorphological features, combined with the local physiographic and climatic features, increased flood and sea storm hazards and risks.

摘要

本文描述了拉帕洛（意大利西北利古里亚）的冲积-沿海平原的人为地貌。自19世纪下半叶以来，拉帕洛（Rapallo）经历了逐渐发展的城市蔓延，在第二次世界大战后变得尤为强烈，并严重修改了以前的地貌。通过对历史和最近的地图和航拍照片进行多时比较，对地理专题图和城市规划文件进行分析，对井眼中的地层数据进行解释以及实地调查活动，来进行形态变化的识别和制图。塑造拉帕洛城市景观的主要人为干预措施是河床改道和河道化，开挖，填土和沿岸堤防建设。这些要素突显了人类在原始环境上的烙印。此外，已确定的人为地貌特征与当地的地理和气候特征相结合，增加了洪水和海上风暴的危害和风险。
