Everything for your home, in one tap
The map splits the flood into small 250 m squares. Search your place or tap your area — the map zooms in and gives you a clear answer for your square.
💧 Depth, arrival time, speed
Tap your square to see the highest water (in floors), the earliest time it could arrive after a breach, how fast it flows and its force — fast water is dangerous long before it is deep.
🏡 Your nearest safe high ground
Every square points to three safe places on genuine high ground, checked for landslide slopes. Tap Show and the map draws the way there with arrows, plus walking directions.
📍 Area report for your ward or village
Switch on Area report and tap a spot — one summary for everything inside the circle: first arrival, deepest water and the nearest refuges. Useful for schools, churches, temples, mosques and village groups.
Mullaperiyar — and Maniyar for Pathanamthitta
The map is built around a worst-case Mullaperiyar dam-break. For people in Ranni, Thiruvalla, Chengannur and Pathanamthitta, a smaller Maniyar Dam layer is also included — switch to it, or show both.

Three flood routes

Coastal double impact
Coastal squares are marked for the sea “hit-back” as the flood reaches the Arabian Sea and rebounds.
Landslide-prone slopes
Steep ground beside violent flow is flagged, so no one picks it as a refuge.
Debris & contamination
Industrial zones, heavy debris and unsafe water are shown square by square.
Works on any phone

In fast-moving flood water, move out of the flow path to higher ground before the water arrives — do not wait, and do not try to cross moving water.

How it was built
Built for public awareness and to give authorities a starting reference. The Mullaperiyar scenario follows a breach through the Idukki reservoir system and down the Periyar to Kochi and the sea, with the Muvattupuzha route included. The Maniyar scenario follows a full-pond breach on top of a peak-monsoon Pamba flood, down to Thottappally. Terrain is corrected against surveyed heights and local flood marks.
