This is the first version of a tool to estimate the possible location of a missed person at Brumadinho/MG. At this city, a huge Dam Burst occured recently and many people died and many more are missing.
The Brumadinho dam disaster occurred on 25 January 2019, when a tailings dam at an iron ore mine in Brumadinho, Minas Gerais, Brazil suffered a catastrophic failure.

This tool requires the latitude and longitude coordinates to calculate the estimative based on the tailing flows.
The algorithm still needs to be improved (so much!). Also, we built it with few data that we had got. To improve it, we need tailings physical-chemical data, topographic map (.csv) of the place, simulations of the reject spreading, and, of course, the latitude and longitude coordinates from the victims' cell phone.
