The Intensity-Duration-Frequency Curve, or IDF Curve, is used in the fields of meteorology and hydrology to estimate the peak rainfall rate, or intensity, during a storm event. The peak rainfall rate experienced varies with the duration of the storm and the location of the storm on the earth...

The shape of the IDF curve is determined by the rainfall theory. 01:36 This graph uses an obsolete theory in the UK called the Flood Studies Report Winter Profile, 01:42 but it gives us the storm's shape as a typical bell-shaped curve. 01:46 This next example shows three differen...

Subsequently, the series of intensity, duration, and return period were fitted to a curve. In hydrology, the equation that represents the relationship between the intensity of precipitation, duration, and frequency has the general form [22]: 𝑖(𝑑, 𝑇)=𝐶(𝑑𝑣+𝑡0)𝑛i(d, T)...

Utilizing the reasonably acceptable distribution function, the regional growth curve was developed. Together with the hourly mean (extreme) precipitation and other dynamic parameters, regional empirical IDF models were developed. The adopted approach to derive station-specific and regional empirical IDF ...
The Intensity–Duration–Frequency (IDF) curve is a graphical representation of the probability of the occurrence of extreme precipitation developed based on extreme probability functions. IDF curves relate rainfall intensity, frequency, and duration, all presented in a set of curves. These curves are...
