The aim of this work is within a detailed geomorphological approach (1:10.000 scale) to analyze the landslide susceptibility in a southern Italy zone (Rossano Calabro-CS) among the watershed of Colognati river and Coserie river. Geological and geomorphological field data had been performed in a G.I.S. environment by the morphometric analysis obtanied from high resolution digital terrain model. In the first step a land forms analysis has been conducted obtaining a strong relationship between geological settings, lithology and weathering. We distinguished fast phenomena (debris flows) by a trigger factor study on landslide top, landslide body and landslide foot, obtaing significant parameters: slope, lithology and prone parameters: high slope profile variations, soil thickness, geological and structural settings, hydrological features.The second step consisted in collecting data which have been crossed with morphological and geological zoning, giving a landslide susceptibility model.

Abstract
The aim of this work is within a detailed geomorphological approach (1:10.000 scale) to analyze the landslide susceptibility in a southern Italy zone (Rossano Calabro-CS) among the watershed of Colognati river and Coserie river. Geological and geomorphological field data had been performed in a G.I.S. environment by the morphometric analysis obtanied from high resolution digital terrain model. In the first step a land forms analysis has been conducted obtaining a strong relationship between geological settings, lithology and weathering. We distinguished fast phenomena (debris flows) by a trigger factor study on landslide top, landslide body and landslide foot, obtaing significant parameters: slope, lithology and prone parameters: high slope profile variations, soil thickness, geological and structural settings, hydrological features.The second step consisted in collecting data which have been crossed with morphological and geological zoning, giving a landslide susceptibility model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
