    Investigation of Meteorological Drought Characteristics of the Great Man-Made River Region (Libya)
    (Springer International Publishing Ag, 2022) Elhaj, Mustafa Ibrahim Mohamed; Keskin, Tulay Ekemen; Jamali, Ali
    In this study, located in the Great Man-Made River region, meteorological drought analysis were conducted for five monitoring stations in Northern Libya, the Standardized Precipitation Index (SPI) method and the Reconnaissance Drought Index (RDI) method were used to determine meteorological drought using monthly total precipitation data, and using mean monthly temperatures data and total monthly precipitation data, respectively. The drought analysis using DrinC software of the Great Man-Made River region for 1-, 3-, 6-, and 12-months SPI and RDI values were conducted and examined in detail. According to the SPI12 month index values, the driest period was determined by 86% in Tripoli Airport and Nalut station, and the least dry period was determined at Sirt station by 39%, and as a result of the analyzes that were conducted, according to the values of the RDI-12 month index, the longest period was determined drought in Zuara station in the year 2000-2001. It was noted that the year 2000-2001 was one of the driest years of all stations, and the other years with high drought rates were 1981-1982, 1984-1985, and 1992-1993.

    Investigation of meteorological drought characteristics of the great man-made river region: a case study of drought in Libya
    (Springer, 2022) Elhaj, Mustafa Ibrahim Mohamed; Keskin, Tulay Ekemen; Jamali, Ali
    Drought is a hidden natural hazard that involves complex climatic systems and has significant environmental and social consequences. Due to the current state of catastrophic climatic occurrences, there has been an increased interest in monitoring droughts in recent years. This study conducted meteorological drought analysis for five monitoring stations in the Great Man-Made River region located in Libya. The Standardized Precipitation Index (SPI) and Reconnaissance Drought Index (RDI) methods were used to determine meteorological droughts utilizing monthly total precipitation data, and mean monthly temperatures and monthly total precipitation data, respectively. The drought analysis of the Great Man-Made River region using DrinC software for 1-, 3-, 6-, and 12-month SPI values were researched. According to the SPI-12-month index values, the driest period was determined by 86% in the Tripoli Airport and Nalut station, and the least dry period was determined in the Sirt station by 39%. It was found that the year 2000-2001 was one of the driest years in all studied stations, and the other years with high drought rates were 1981-1982, 1984-1985, and 1992-1993.
