The overall dispassionate of the study is to produce information for an enriched land use planning with deference to flood hazards. The study evaluates the potential impact of environment change by pretending a dam break scenario in a high forceof rainfall event and estimates the vulnerability risk in the downstream region by integrating ArcGIS and Hydrologic Engineering Centers River Analysis System (HEC-RAS) technologies. In the past century, the indication of climate changes ispragmatic in terms of intensification in high intensity rainfall events. These events are of high concern, as amplified inflow rates may increase the prospect of a dam failure, leading to higher extent flooding events involving multiple significances. The 100 year historical rainfall data for the central Mississippi region reveals an increased trend in the intensity of rainfall rates after the 1970s. With more than 10% of high hazard dams in the central region, the damage
