Webmethods. The developed IDF curve delivers larger amount of intensity than that of IDF curve developed by ERA for similar time of duration in minutes. Finally IDF curves were developed for the towns and recommended for the design of storm drainage system. Keywords: Rainfall Intensity, Rainfall Duration, Time of Duration, IDF 1. Introduction 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…
