GeoDatabase and Modeling Code used for Landslide Hazard and Susceptibility Mapping in Eastern and Northern Kentucky

We created a landslide susceptibility map using spatial soil property features extracted from the NRCS WSS that include percent sand, percent silt, percent clay, saturated hydraulic conductivity, available water capacity, one third bar water content, plasticity index, and liquid limit, all of which were used as features in the logistic regression analysis. We also used satellite soil moisture data, and a high-resolution (1.5 m) LiDAR-derived digital elevation map (DEM) which include slope, aspect, curvature, elevation, roughness, and plan curvature. We show that using publicly available data, a multi-temporal landslide hazard map can be created that will produce a close-to-real time landslide susceptibility map. The landslide hazard map derived from the limit equilibrium analysis tells us the evolution of the landslide development temporally and spatially, whereas the landslide susceptibility map derived statistically indicates the locations of possible landslides in the long term.
