ABSTRACT

Using a comprehensive cartographic product, this paper aims to illustrate the evolution of the urban geomorphological setting of the urban coastal belt of Cagliari (southern Sardinia, Italy, western Mediterranean Sea). The geomorphological map (1:14,000) presented herein summarizes different data (e.g. urban development, anthropogenic features, geomorphological elements, recent deposits, sedimentological distribution, hydrodynamics and ecological components) acquired through an integrated sea-land approach and a multidisciplinary-multitemporal investigation.

The main significant environmental changes are linked to urbanization, the development of port infrastructures (embankments along the shoreline and the construction of the canal harbour), remediation work and filling activities, and the hardening of dune and beach systems and cliffs. These man-made interventions have increased the vulnerability of the shore zones to flood hazards and risks, which are linked to sea-level rises and global warming.

摘要

本文使用综合的制图产品，旨在说明卡利亚里（意大利南部撒丁岛，地中海西部）城市沿海带城市地貌环境的演变。本文介绍的地貌图（1：14,000）总结了通过综合海陆方法和多学科，多时相研究获得的不同数据（例如，城市发展，人为特征，地貌要素，近期沉积物，沉积物分布，水动力和生态成分）。

主要的环境变化与城市化，港口基础设施的发展（沿岸的堤防和运河港口的建设），整治工作和填土活动以及沙丘和海滩系统以及悬崖的硬化有关。这些人为干预增加了沿海地区遭受洪水灾害和风险的脆弱性，而洪水灾害和风险与海平面上升和全球变暖有关。
