Derivation of Huff Curves for the Four Stations in Great Karun River in Khuzestan Provinvesince S

چکیده مقاله

The first step in scientific water resources management is good understanding of the temporal precipitation pattern. One of the main tools in understanding the rainfall pattern is plotting the Huff curves. This is true especially in arid and semi-arid regions encountered with water shortages. These help decision makers in understanding temporal characteristics of rainfall, which in turn can help efficient management of water resources. Temporal distribution of rainfalls interested by many investigators in the field of hydrology such as Yen and chow (1980), Loukas and Quick (1994), Todisco (2014), Huff (1967 & 1990) and many others. Furthermore, illustration of Huff curves for different rain gauge stations performed by many researchers such as Azli and Rao (2010), Awadallah and Younan (2012), Yazdi et al. (2016), Shokri-koochak et el. (2011), and many others. In a recently published work by Ewea et al. (2016) the Huff curves were plotted for the city of Makkah Al-Mukkaramah in Saudi Arabia. Based on our best knowledge, there is no comprehensive scientific work carried out on illustration of Huff curves in Great Karun River basin, located in south west of Iran. Therefore, the main objective of this study is illustration of Huff curves and analysis of storm pattern during the rainfall occurrence in the four selected stations, including the Dez dam, Abdul-Khan, Gotvand and Ahwaz. These selected stations are located in Karun River basin, Khuzestan province, Iran.
