IDF Curves 101 — Climate Data Canada

An intensity-duration-frequency curve (IDF curve) is a mathematical function that relates the rainfall intensity with its duration and frequency of occurrence. These curves are commonly used in hydrology for flood forecasting and civil engineering for urban drainage design. However, the IDF curves are also analysed in hydrometeorology because of the interest in the time concentration or time-structure of the rainfall. Additionally, Heidari et al., (2024) recently developed IDF curves fo… Webeta numeric value, giving duration exponent (deﬁning slope of the IDF curve) d positive numeric value, giving duration eta2 numeric value, giving a second duration exponent 2 (needed for multiscaling).
