The presence of sloping ground surfaces is common. In slightly inclined natural slopes, susceptible to deep landslides, the unsaturated condition of shallow soil horizons affects deep pore water pressures and, therefore, global stability. The stability of steep mountains covered by shallow deposits is often guaranteed by a shear strength contribution related to the unsaturated condition. In this case, the degree of saturation plays a key role in determining which rainfall events can act as landslide triggers, consequently controlling the post-failure evolution. Partial saturation is the basic characteristic of soils used as construction materials of geo-structures such as levees, dikes, and dams. It governs the structure behavior during construction phases, in serviceability, and in extreme scenarios. Hoping to provide a bridge between theoretical research and practical applications, this Special Issue collects quality contributions related to natural and artificial slopes under unsaturated conditions, focusing on aspects such as: water retention and transport properties, mechanical behavior, advances in experimental methods, laboratory and in situ characterization, field monitoring, geotechnical and geophysical field tests, landslide investigation and prevention, the design and maintenance of engineered slopes, and the constitutive and numerical modeling of hydro-mechanical behavior. 606 $aTechnology: general issues$2bicssc 610 $acalibration 610 $acapillary barriers 610 $acommercial experimental techniques 610 $adebris flow 610 $ain situ characterization 610 $ainfiltration 610 $ainstallation 610 $aLAMP 610 $alandslide 610 $alateral resistance 610 $alimit equilibrium solution 610 $amonitoring 610 $an/a 610 $apyroclastic soils 610 $arainfall 610 $ariverbank 610 $aRuedlingen field experiment 610 $asilty sands 610 $aslope stability 610 $asoil moisture 610 $asoil slide 610 $asoil water content 610 $astability analysis 610 $asuction 610 $atransient seepage 610 $atriaxial tests 610 $aunsaturated conditions 610 $aunsaturated permeability curve 610 $aunsaturated slope 610 $aunsaturated soils 610 $awater retention 610 $awater retention curve 615 7$aTechnology: general issues 700 $aVassallo$b Roberto$4edt$01324796 702 $aComegna$b Luca$4edt 702 $aValentino$b Roberto$4edt 702 $aVassallo$b Roberto$4oth 702 $aComegna$b Luca$4oth 702 $aValentino$b Roberto$4oth 906 $aBOOK 912 $a9910557747003321 996 $aNatural and Artificial Unsaturated Soil Slopes$93036311 997 $aUNINA
