Where did the flood hit ┬╖ What was damaged ┬╖ Who is cut off
The evidence
Every answer on the dashboard comes from free satellite data and the map as it was before the flood. Here is the proof, step by step, for the Trishuli flood of 26 August 2026.
Sentinel-1 sends its own radar waves, so it works through cloud, day and night. We compare the same valley before and after the flood. Drag the line to compare. This is the 3.8 km around Rasuwa Gadhi, where the radar changed most.
Sentinel-2 takes normal colour photos, but monsoon clouds hide the valley. Only 67.9% of the valley was cloud-free after the flood, so photos only confirm the radar where the sky is clear.
Draw a box, give the flood date, press Run. Everything below happens by itself in 2тАУ6 minutes, for any area and any date.
Copernicus EMS mapped this flood by hand from very sharp images (0.3тАУ0.7 m). We used them only to check our result, never as an input.
Honest reading: what we map as confirmed is almost always real (high precision), but alone it misses part of the outer edge of the debris, where radar and photos show little change. The lighter possible damage zone (land next to real damage that is no higher above the river) closes most of that gap, and it adds nothing on the no-flood test below. Its four settings were picked after checking against these maps, so we show both numbers.
The same box on a dry-season date (15 April 2026), run with the same settings. A system that "sees" floods everywhere would fail this test.
No settings were changed between these runs. Each one is a saved result you can open.
In a disaster, a wrong number can send a rescue team to the wrong place. So the language model is only allowed to write blanks; a checker rejects any digit it writes, and our code fills each blank from the maps.
Every cut-off village gets a rescue priority out of 100, computed by code (not by the AI) from four parts:
People inside a mapped flood area can check their danger level, call emergency numbers, and send their GPS location to the rescue team's inbox (PIN-protected). Requests from outside the flood area, or far from the chosen place, are refused, which stops casual fake requests.
