Hydrometeorological features and landslide surface velocity datasets (Séchilienne, Viella, Villerville)

This dataset provides the input tables used to model deep-seated landslide surface dynamics at three instrumented sites: Séchilienne (France), Viella (France), and Villerville (France). For each site, we provide (i) observed and preprocessed surface velocity time series and (ii) hydro-meteorological feature tables derived from rainfall (R), effective rainfall (ER), and groundwater level / piezometric indicators (GWL, or WLI/WLM at Séchilienne).The feature tables include rolling sums and maxima over multiple windows, saturation and anomaly indices, event-based strength metrics, and groundwater lag/difference/statistics features. All tables are time-indexed with a Date column to enable direct merging and reproducible model training.The accompanying open-source code for feature computation and XGBoost modelling is available in the associated GitHub repository : Béjean-Maillard, O. (2025). Hydrometeorological features and XGBoost modelling (v0.1.0). GitHub repository.
