FLD stands for Flood, and there are several synonyms that can be used to describe this natural phenomenon. Some of the common synonyms include deluge, inundation, torrent, overflow, and spate. Floods occur when there is an excessive amount of water that overflows its normal confines and causes damage to property and even human life. Other synonyms such as flash flood, river flood, coastal flood, or urban flood may be used to specify the type of flood that is being referred to. Effective preparation, including emergency kits, evacuation plans, and flood warning systems can help mitigate the harmful effects of floods.
