Floodplain mapping is the process of identifying and delineating areas that are prone to flooding. This involves analyzing historical flood data, rainfall patterns, and topography to create detailed maps that show where water is likely to flow during heavy rain or storm events. These maps help communities understand their flood risks and plan accordingly. The maps are essential for urban planning, emergency management, and insurance purposes. They inform decisions about land use, construction, and disaster preparedness. By using floodplain maps, local governments can implement strategies to reduce flood damage and protect public safety in areas like riverbanks and coastal zones.
