摘要

本文描述了一个数据整合程序的方法学实例,以提高对与亚平宁南部(意大利)地震区有关的滑坡灾害的认识。关注的焦点是遥感数据。利用详细的地形、地球物理、岩土和水文地质数据作为地面真实资料,验证了分析结果。从1993年底开始研究的现象是一种土流。提出的方法建议结合使用DEM、多时相全色可见光航空照片和热红外图像。这些数据与多学科监测数据之间的整合证明是有用的。可以清楚地确定主要水文地质格局、地质地貌格局和潜在不稳定区域。在进行分析所需的相对较短的时间内,可以通过天气坡度视图获得洞察力。所建议的方法可被视为对评价滑坡危害的有益贡献,特别是在紧急时期。

Hydrogeological monitoring and image analysis of a mudslide in Southern Italy

This paper describes a methodological example of a data-integration procedure to improve the knowledge of landslide hazard related to a seismic area in the southern Apennine (Italy). Attention is focused on remote sensing data. The analysis is validated using detailed topographical, geophysical, geotechnical and hydrogeological data as ground truth. The investigated phenomenon, which started at the end of 1993, is an earthflow. The presented methodology recommends the combined use of DEM, multi-temporal panchromatic visible aerial photographs and thermal infrared images. The integration between these data and multidisciplinary monitoring data proved useful. The main hydrogeological pattern, the geological and geomorphological framework and the areas of latent instability can be clearly determined. Insight can be gained through the synoptic slope view in the relative short time needed to carry out the analysis. The proposed approach can be regarded as a useful contribution to the evaluation of landslide hazard, particularly during emergency periods.
