Coastal flood hazard mapping (CoFHaM) is a tool used to determine flood zone limits inland and in other areas exposed to coastal floods due to different hazards such as storm, surge waves, sea level rise caused by climate change, inland storm surge, heavy rainfall, among others. Its areas are identified through maps made by one or more researchers using the Geographic Information System (GIS) software. Generally, its maps display particular levels of flood hazards and risks, with different parameters defined as low, medium, and high.
