Intensity duration curve

Webintensity-duration-frequency (IDF) Curves [7]. This project will be involved in the development of intensity-duration and frequency curves in order to solve problems related to hydraulic design. Materials and Methods To achieve the objectives of this research by determining the intensity -duration frequency curves for WebB. Intensity Duration Frequency Curves: In hydrology, frequency analysis of station rainfall data is done for use in design of bridges and culverts on highways, design of storm drains etc. With the advancement of science of hydrology rainfall frequency analysis is done using Gumble’s extreme-value distribution and annual series data.
