Generation of Idf Eqution Case Study Al- Shuwaija Watersheds/(Iraq-Iran)

Abstract

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.

Studying and Assessing Surface Water Use of Shuwaija Marsh within Wasit Governorate-Iraq

“…The lack of water sources during droughts, in addition to climate change, has a clear impact on the marshes. Therefore, it is necessary to evaluate hydraulic and hydrological behavior by estimating the amount of water revenue through rainfall (Ali et al, 2023) (Mandali, Qazania, Tursaq, Mirzabad, Galal Badra, al-Chabbab, al-Teeb, and Dwaireeg) using regression models developed for the western and southern United States. The optimal investment in a region's natural water resources is one strategy to provide large quantities of water that may help mitigate the harmful effects of climate change (García-Ruiz et al, 2011).…”
