Flood Level of Protection
Flood Level of Protection : "Level of Protection represents the ability of a structure or a system to contain a flood of a given size with a high degree of assurance. It can be defined by three different methods: (1) As the average return period in years (e.g. 100-year, 500- year, etc.) of the largest flood that can be expected to occur at that average frequency; (2) As the maximum derived discharge expected from a flood developed from a set of specific hydrological conditions (e.g. as the Standard Project Flood); or (3) As the discharge of a significant historical event". (Galloway, A CA Challenge, 2007, 14)
