Landslide processes and Andosols: the case study of the Campania region, Italy

摘要: Most catastrophic mudslides in Campania are related to soils developing upon pyroclastic materials covering carbonatic relieves of the Campanian Apennines. The soil observed detachment crowns investigated fast mudflow consisted fertile Andosols (generally Hapludands and Udivitrands) that were very sensitive anthropic or natural changes. This is due unique chemical, physical, morphological hydrological behaviour these soils, including (i) high water retention near saturation, (ii) hydraulic conductivity, (iii) smeariness most horizons, (iv) vertical lateral variability properties horizons. Aspect important determining susceptibility landslide triggering induce higher storage especially northern aspect soils. It clear stability requires conservation, implemented through appropriate forest planning management. Improved risk management policies necessary preserve continuity decrease both surface erosion human lives infrastructure.
