【 摘 要 】

The analysis and evaluation of actual hydraulic operation at the level of a distributary canal (secondary level) and its related outlets is based on suitable hydraulic indicators such as equitability (PE), dependability (PD), adequacy (PA), and flexibility (F); this is the basic goal of the present study, which uses the hydrodynamic Simulation Irrigation Canal model (SIC) for the first time in an analysis in Iraq. One of the distributary canals in the Kifil-Shinafiya project (KSP), located at the middle of Iraq, was selected for the study of these indicators by evaluation of the gaps between demand flows and actual deliveries at the outlet structures along the canal. The selected canal serves an area of 710 hectares with, alongside the head regulator, sixteen outlet structures and two cross regulators. The study includes a range of field measurements such as the actual water levels and the actual corresponding discharges at outlets for twenty-four months, covered four cropping seasons, over two years, as eight measurements were taken per month at each outlet from October 2014 to September 2016. The maximum measured discharge at the head regulator during the study period was smaller than the design discharge. The results showed that the equity indicator (PE) was generally good, except for the months of May and October; while the dependability indicator (PD) was good in all head outlets but it was only fair for other outlets. The adequacy indicator (PA) was poor throughout the study period. The dependability and adequacy indicators in the winters were seen to be better than in the summers.
