Flood safety planning
In the United States, the National Weather Service gives out the advice "Turn Around, Dont Drown" for floods; that is, it recommends that people get out of the area of a flood, rather than trying to cross it. At the most basic level, the best defense against floods is to seek higher ground for high-value uses while balancing the foreseeable risks with the benefits of occupying flood hazard zones. : 22–23  Critical community-safety facilities, such as hospitals, emergency-operations centers, and police, fire, and rescue services, should be built in areas least at risk of flooding. Structures, such as bridges, that must unavoidably be in flood hazard areas should be designed to withstand flooding. Areas most at risk for flooding could be put to valuable uses that could be abandoned temporarily as people retreat to safer areas when a flood is imminent. Planning for flood safety involves many aspects of analysis and engineering, including:

observation of previous and present flood heights and inundated areas,
statistical, hydrologic, and hydraulic model analyses,
mapping inundated areas and flood heights for future flood scenarios,
long-term land use planning and regulation,
engineering design and construction of structures to control or withstand flooding,
intermediate-term monitoring, forecasting, and emergency-response planning, and
short-term monitoring, warning, and response operations.Each topic presents distinct yet related questions with varying scope and scale in time, space, and the people involved.
