WebOverall, the simulating data in summer is more accurate than that of other seasons. Equidistance quantile-matching (EQM) method which integrated spatial and temporal downscaling was used to quantify the variations in rainfall intensity and update Intensity-Duration-Frequency (IDF) curves in climate scenarios [42,43]. Web1 day ago · The ordinates of the rainfall mass curve and particular stoms for year 1980 are given below. For the other years, the records were analysed for various durations as shown in the following Tables \( (1981-1995) \) 1. Compute the maximum rainfall intensities for various durations for year 1980 2. Plot the intensity duration curve for year 1980 ...

WebThe equation expressed in the following form was utilized (Chow et al., 1988): where i is the rainfall intensity (inches/hour); t is the duration (minutes); a, b, and k are constant parameters. The constant parameters were determined using the statistical method of least squares by minimizing the Root Mean Square Error. 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 for … limiting competition
