What the levels mean
Each district gets a Low, Medium, or High estimate for every hazard. "Observed" levels come from a directly measured event, such as a satellite-recorded flood extent. "Estimated" levels are modelled from proxies such as terrain, historical rainfall, or monitoring-station readings, and are not a forecast or a probability. A level never combines more than one hazard, and "Not enough data yet" means exactly that — not a safe rating.
What this means if you're buying or renting
A High estimate for Kalasin is a prompt to ask more questions — request a site-specific flood or engineering survey, check the property's ground floor level and past flood history with the seller or agent, and review local drainage before committing. A Low estimate does not guarantee a property is risk-free, and none of these levels replace a professional inspection.

Frequently asked questions
Which district in Kalasin has the highest Flash-flood terrain susceptibility?
Huai Mek has the highest Flash-flood terrain susceptibility in Kalasin, at Low.
Which district in Kalasin has the lowest Flash-flood terrain susceptibility?
Huai Mek has the lowest Flash-flood terrain susceptibility in Kalasin, at Low.
Where does this data come from?
Terrain-derived flash-flood indicators (HAND + slope + OSM drainage proximity; NOT a forecast or probability, not calibrated against observed events) from Copernicus DEM GLO-30 (via Mapterhorn terrain tiles) and OpenStreetMap waterway data. The banded metric flags whether the region CONTAINS terrain susceptible to flash flooding somewhere within it -- not the susceptibility of the region as a whole, and not of any individual property.

What do the Low, Medium, and High hazard levels mean?
Low, Medium, and High are screening estimates, not a forecast or probability. Each hazard is scored on its own — there is no single combined risk score across hazards.
