Probability density function
Culvert, screen and outfall manual, (CIRIA C786) published by CIRIA in 2019, defines probability density function (PDF) as: ‘The mathematical function that describes the relative chance of observing values of a continuous variable. For example, a probability density function could describe the chance that the measured river flow could equal a certain value (for example 100 m³/s), or the chance that a single culvert has a certain percentage blockage.’
