The phenomenon of floods considers one of the most critical ecological hazards that may lead into multiple of environmental and human disasters, particularly, to the sustainable development process in the study area; since the forceful inflow of the current waters into valleys turns into a destructive deadly power to the railway stations, roads, and establishments. Hereby, researchers with environment's risks have had to consider this repetitive phenomenon. The researcher has selected Safaga area to become the study area to examine floods' hazards and their impact on sustainable development, as floods are one of the most important ecological phenomena burden with environmental risks to the Red Sea governorate, specifically, the study area (Safaga) for being a promising area of future economic growth and for including several risky valleys during floods' occurrence. In order to set present and future developmental programs, both natural and human risks should be included within the framework of sustainable development to restrict disasters. Geographical Information Systems (GIS) play a significant primary role in floods and their hazards; in the past few years, as the GIS have been capable of providing decision-makers with multiple data that have facilitated management of the disaster, regarding the ability of inquiring and planning for hazards. This research comes out with a selection of approaches for restricting disaster of floods through keeping inhabited areas away from floods and disasters ways, establishing also a group of institutions that would be capable of resisting the expected floods such as bridges and dams; taking into consideration the cost and benefit of these establishments; alleviating this through reducing losses by counting on planning of lands' utilization in the exposed to-floods areas, particularly, the coastal and defining determinants of directing these uses according to their economic or spatial value. In addition, people should be warned at floods duration through using modern techniques and methods of prediction using the GIS and means of protection from floods' hazards by seeking the protection establishments in case of inhabited areas such as (Safaga city – the fishermen' villages – land roads – tourist villages), defining type of risk for each and how to protect it when hazards are highly risky.
