Abstract
A This analytical study examines the characteristics of torrents in the Large Al-Khazir basin area, spanning approximately 3303 square kilometers in northern Iraq. The basin is situated at the intersection of three governorates: Nineva, Erbil, and Kerkuk, and it drains into the Large Zab River at the Wirdik location. Hydrographic charts were prepared to support the investigation. The research primarily focuses on the geological and tectonic features of the region, along with the soil composition and vegetation cover thickness. Additionally, the study analyzes the geographical and hydrological slope characteristics of nine secondary basins, which collectively account for approximately 74.25% of the total basin area. The analysis encompasses the basin's geometrical and morphometrical properties, including hydrological attributes such as soil conditions, vegetation coverage, longitudinal and width measurements, rainfall recurrence, and absorption (flow CN). To this end, Snyder's Modified Method (2006) is employed, considering various factors contributing to the climax flow (ct) ranging from 2 to 2.2, as well as the Climax Flow Coefficient (cp) ranging from 2 to 6.5. The obtained results are recorded and analyzed within high, medium, and low limit parameters, while addressing parallel cases that align with the inherent characteristics of the studied basins. Throughout the investigation, a total of 49 hydrographs are generated, providing comprehensive insights into the torrent features under various scenarios within the examined basins. Upon evaluating each case, it is observed that Basin 9 exhibits the highest potential for attaining QP, surpassing other torrent characteristics. Basin 7 and Basin 8 follow, while Basin 6 demonstrates the least capacity to achieve Q. Furthermore, all the studied basins display varying degrees of high torrent characteristics, with their temporal and situational values offering valuable insights for the development of the respective areas. By mitigating the risks associated with torrents concerning human settlements, plantations, and transportation, these regions can be further enhanced, including the implementation of water storage strategies for dry seasons.
