End-to-end riverbank erosion and accretion analyzer with satellite data fetching via STAC API, multi-index water extraction (NDWI/MNDWI/AWEI), and grid-based + transect-based change analysis.
RiverBankErosionAccretion_V2 is an advanced QGIS plugin that automates riverbank change analysis from satellite data acquisition to validated erosion/accretion mapping. Features include STAC API-based Landsat/Sentinel-2 data fetching, multi-index water extraction with Otsu thresholding and ensemble voting, grid-based area change analysis, transect-based rate-of-change computation, and optional validation against JRC Global Surface Water reference data.
