Abstract:

 Two models were applied in this study for the aim to generate future weather elements and simulate future runoff in Horan Valley, one of the largest valleys in the Iraqi western desert. Weather data from the last ten years was used by the climate model to generate future weather elements for the next ten years (2026-2035), such as rain and temperature. The generated results indicate that maximum rainfall is expected in April 2026 (91.6 mm, November 2030 (60.3 mm, January 2031 (76.4 mm), and December 2035 (68.3 mm). Results of this model are used as weather input data in the hydrological model to simulate and predict future runoff for Horan Valley. In the model simulation, the watershed delineation yielded 106 hydrological response units and 24 sub-basins. The future runoff quantities estimated by this model represent the expected amount of water that will be directly added to the Euphrates River. Results from the model simulation show that the maximum runoff during the next ten years occurs in April 2026 (18.4 mm), November 2030 (13.3mm), and January 2033 (17.4 mm), where the runoff periods are concentrated during the rainy season from November to April. The estimation of future runoff quantity in Horan Valley is very important to provide accurate future forecasts of water resources in the study region.
