Identification of conditioning elements in a specific context is critical for spatially mapping flood susceptibility. Remote sensing and geographic information systems have evolved in recent decades as instruments for performing hazard management and geospatial mapping using multi-criteria decision models. As a result, rising global average temperatures, which indicate an excess of energy in the atmosphere, and the conversion of more and more natural surfaces into constructed areas are the primary causes of an increase in the number of floods and flash floods around the world. This fluctuation in distribution causes two hydrological extremes: “Floods” and “Droughts.” A large increase in the number of extreme meteorological and hydrological events has been reported because of recent climatic changes as well as major changes in land usage. Because the overall amount of water in the cycle is constant, even if the distribution changes across time and space, the hydrologic system is termed closed. Water is the most valuable natural resource on the planet and is essential for life.
