Baadhiबाढी

Flood & debris damage from space — Sentinel-1 radar, Sentinel-2 optical, Copernicus DEM and pre-event OpenStreetMap.

Live engine

You are using the complete Baadhi, running on the owner's laptop: draw any area, choose a flood date and it runs from raw satellite data (about 4–5 minutes, one analysis at a time; each visitor gets 3 per hour). Saved analyses open instantly and without limit.

Public demo

These are saved analyses of real floods, shown exactly as the dashboard produces them. Choosing any area and date runs live on a local server (it downloads Sentinel-1/-2 data and the pre-flood map for that place), so it is switched off here. When the owner's live engine is online, this same address opens the complete site instead. Source code, README and report on GitHub →

    Cut off from hospital or town

    SettlementBeforeNowOn foot

    Minutes to the nearest hospital or clinic on the pre-event road network (typical speeds). "Now" removes roads under water/debris and bridges over an affected reach. Verify: still reachable, but only along roads that touch the footprint or run within 20 m of it.

      What this analysis cannot tell you
      • Sentinel satellites pass every few days: water that drained between passes is not seen, and nothing is predicted in advance.
      • Radar is blind on steep slopes facing towards or away from it; optical images need clear sky.
      • A building "hit" lies inside the flood/debris footprint at 10 m — it may be standing.
      • Buildings, roads and villages come from OpenStreetMap before the event: unmapped ones are not counted.
      • Travel times use typical speeds; roads outside the analysed area are assumed passable.

      Where would a flood go?

      Click a point upstream — a glacial lake, a landslide dam — to trace the path water takes down the valley and list the settlements along it.

      Path follows the steepest descent on Copernicus DEM (90 m). "Directly in the path": ≤ 20 m above the river; "possibly": ≤ 60 m. No arrival times — they depend on the volume released.
