Al- Shuwaija , Rainfall, Frequency, Duration, IntensitiesAbstract
One of the most useful tools in water resources engineering is the Intensity-Duration-Frequency (IDF) relationship, which may be used in the planning, design, and operation of water resource projects and a wide range of engineering initiatives to mitigate the effects of flooding and torrents Al- Shuwaija in addition to the designs of rain networks within Cities nearby.
This research aims to find the curves of intensity, duration and frequency (IDF), determine the intensity of rainfall in Shuwaija, and derive an experimental method for estimating rainfall intensity. Rainfall records dating back 20 years were relied on as well as the processing of missing data for five plants. A set of tests was used for probability distributions using programs (ESY FIT, HYFRAN-PLUS), and Log-person type 3 was found to be the appropriate option for the probability distribution. For the AL- Shuwaija area, any return time with a given storm length may be predicted using a median empirical formula. The research found that the highest intensities occur over the shortest periods of time and that these intensities vary greatly with the return period, but that over longer periods, there is no fluctuation in intensities.
