This paper aims to propose a methodology of spatial analysis, through G.I.S. techniques, to study hydrogeological instability processes and how they relate to the fluvial morphogenesis, which characterizes many mountain fluvial basins in Italy.

This basin is characterized by severe instabilities caused by intense and widespread slope instability, by sediment-load processes, by the effects produced by the Camastra’s dam and by a score of river works. The use of G.I.S has allowed us to complete a comparative analysis of these numerous characteristics of the Inferno creek watershed, and it has proved adept at finding out the interactions between the slopes’ dynamic and the rivers’ dynamic, especially in a high hydrogeological instability basin, the fluvial morphology turns out to be strongly influenced by the phenomena of morphointrusion of landslides into the river bed.

Abstract

This paper aims to propose a methodology of spatial analysis, through G.I.S. techniques, to study hydrogeological instability processes and how they relate to the fluvial morphogenesis, which characterizes many mountain fluvial basins in Italy. More precisely, this methodology has been applied to study the Inferno creek watershed (Basilicata, Southern Italy). This basin is characterized by severe instabilities caused by intense and widespread slope instability, by sediment-load processes, by the effects produced by the Camastra’s dam and by a score of river works. The use of G.I.S has allowed us to complete a comparative analysis of these numerous characteristics of the Inferno creek watershed, and it has proved adept at finding out the interactions between the slopes’ dynamic and the rivers’ dynamic, especially in a high hydrogeological instability basin, the fluvial morphology turns out to be strongly influenced by the phenomena of morphointrusion of landslides into the river bed.
