Hydrometeorological features ans surface velocity measurements for the Séchilienne landslide

The Séchilienne dataset includes processed daily surface-velocity time series from five monitoring plots (E-A13, E-A16, E-C2, P1103 and P1300) representative of a high-activity unit of the landslide (vel_decomposed_Sechilienne.csv). E index denotes extensometers, whereas P denotes tacheometric station (prism reflectors). Data preparation steps are documented in the Lineage section.

The predictor dataset (hm_features_Sechilienne.csv) includes four forcing series: net rainfall (R), effective rainfall (ER), and two synthetic groundwater-level series (GWLI and GWLM) derived from a rainfall–discharge model that conceptualises hillslope hydrology. Further details are provided in Béjean-Maillard et al. (2025). The remaining columns contain the full set of 404 predictors computed from these forcing series. The predictor naming convention is described in the Lineage section.
