    🌊 Modeling a potential dam breach — and how panic spread beyond the real watershed

    This project assessed the potential consequences of a dam failure at a mine-water impoundment in the Svystunova Gully.

    🔹 Reconstructed the original pre-impoundment terrain from archival topographic maps.
    🔹 Used Sentinel-based land-cover classification to assign variable Manning’s roughness coefficients.
    🔹 Built a modern DEM including the dam structure and current flooded zone.
    🔹 Simulated dam-break flood dynamics in GRASS GIS — frame by frame.
    🔹 Produced a video visualization to help local communities understand real risks (and ignore fake ones).
    🔹 The results were later featured in regional media and used in discussions about mine-water safety.

    🎥 Watch the short video visualization:
