Probability of occurence (as part of the flood risk assessment)

Definition

Probability of occurence is the propability of a natural event of a given magnitude being equalled or exceeded in a given period of time. [*1] It refers the chance of occurrence of one event compared to the population of all events. Therefore, probability is dimensionless. It is however, often referenced to a specific time frame, for example, as an annual exceedance probability or lifetime exceedance probability.

Context

 

Methodology

Probability can be expressed using:

  • probability:
    • probability of a particular event
    • annual probability of exceedance
    • lifetime probability of exceedance
  • frequency:
    • annual exceedance frequency
    • return period
