The presented optimization model was used for a super large-scale real pipeline project with a discharge of 8.5 m3/s, called the ‘Qadir project’, in the southwest of Iran and the results are presented in this section. The pipeline, with a length of 127 km and a diameter of 2,250 mm, transfers water from the Karkheh dam reservoir to Ahvaz city. The plan and profile of the pipeline are presented in Figure 6 and the specification of the pipes and pumping station are shown in Table 1.
