Advances in Shallow Landslide Hydrology and Triggering Mechanisms: A Multidisciplinary Approach

[...]the hydrological dynamics leading to shallow landslide initiation, the hydraulic properties at the slope scale, and the role of hysteretic effects as well as the soil nonequilibrium processes in slope stability assessment are still not completely understood and require further investigation. The main topics of the papers included in the special issue regarded the following: (i) Analysis and modeling of landslide hydrology at different scales (ii) Hydrological modeling of the materials forming deposits of past landslides (iii) Field hydrological monitoring of slopes (iv) Seasonal, yearly, and interyearly hydrological dynamics of a slope (v) Models of hydromechanical triggering of shallow landslides (vi) Antecedent and initial hydrological conditions that predispose to landslide triggering (vii) Porous media dynamics in landslide systems (viii) Landslide water balance models Ten papers were submitted for this special issue. Monitoring of water content and pore water pressure trends and of the flow directions in a laboratory small-scale physical model of the real landslide allowed recognizing preferential flows and seepage-induced internal erosion in the deposit that could lead to the triggering of shallow instabilities.
