Kébir Rhumel IEHPI: indicators, weights, scores and robustness results

Data and code supporting the manuscript "Integrated eco-hydrological prioritization of the Kébir Rhumel sub-basins (north-eastern Algeria) using the TanDEM-X DEM, remote sensing and hybrid AHP–entropy weighting" (Derradji et al.), submitted to CATENA. The Integrated Eco-Hydrological Prioritization Index (IEHPI) ranks the seven sub-basins (SW1–SW7) of the Kébir Rhumel catchment for soil-conservation planning. Fourteen indicators derived from the TanDEM-X 30 m EDEM, Sentinel-2, CHIRPS, OpenLandMap/SoilGrids, ESA WorldCover and OpenStreetMap are grouped into four dimensions (morphometric, ecological, hydro-environmental, anthropogenic), weighted by a hybrid of a two-round Delphi–AHP elicitation (six judges) and Shannon entropy, and aggregated into a 0–1 score. The ranking is tested against three DEMs (TanDEM-X, SRTM GL1, ALOS AW3D30), weight perturbations, a seeded Monte Carlo simulation, alternative representations of the hydro-environmental dimension and the drainage-network threshold. The archive contains the sub-basin boundaries; the raw and normalized indicators for the three DEMs; the individual and group AHP matrices of both Delphi rounds; the dimension weights, IEHPI scores and priority classes; the sensitivity, uncertainty, threshold and DEM-comparison results; the Google Colab notebooks of the processing chain; and a stand-alone script (code/rebuild_tables.py, numpy/pandas/scipy only) that recomputes all derived tables and checks 52 reference values of the manuscript.
