Urban and small catchment landslides and floods are common types of hazards caused by intense rainfall. The detailed geomorphological mapping and analysis of the superficial hydrographic network are fundamental tools to assess the geo-hydrologically critical areas. In this study, the Feltrino Stream and Lanciano area (Adriatic coastal-hills) were investigated through a basin-scale and urban-scale geomorphological analysis – which incorporated temperature-rainfall and morphometric analyses, and the acquisition of geomorphological and hazard data, integrated with geomorphological fieldwork and mapping. The creation of a geodatabase and the data overlay led to assess the landslide–flood critical areas through geomorphology-based matrices. This study aimed to define the distribution of landslide–flood historical/recent events and related critical areas for the realization of an urban EWS, composed of a network of nine gauges, integrating the existing regional monitoring network. It defined a local alert system for landslide–flood and could support real-time communication for civil protection purposes.

城市和小流域的滑坡和洪水是暴雨造成的常见危害类型。浅层水文网络的详细地貌制图和分析是评估地文水文关键区域的基本工具。在这项研究中，通过流域规模和城市规模的地貌分析研究了Feltrino河和Lanciano地区（亚得里亚海沿海丘陵），该分析结合了温度雨量和形态分析，并获得了地貌和灾害数据，并与地貌野外工作和制图。地理数据库的创建和数据叠加导致通过基于地貌学的矩阵评估滑坡洪水关键区域。这项研究旨在定义滑坡洪水历史/近期事件和相关关键区域的分布，以实现城市预警系统，该系统由九个测量仪组成，并整合了现有的区域监测网络。它为滑坡洪水定义了一个本地警报系统，并且可以支持出于民防目的的实时通信。
