Hi Maning, in Colombia we are using humanitarian tag:

flood_prone = yes
flood_prone = "tag info"

San Estanislao de Koska


For "tag info" we describe at least flood date, so evidence is explicit
over years coming.  This way we get information for risk management and
population learning.

Andrés Calderón developed a methodology to get flood prone using Landsat
and Modis (in progress) Nasa imagery.

Hope this could help and appreciate your comments,

Humberto Yances
