| Summary: | Recent years have witnessed significant declines in surface water quantities as a result of population density, climate change, and water pollution. Iraq is one of the countries that has suffered from water scarcity, particularly due to the upstream countries' water usage policies on the Tigris and Euphrates rivers. All indicators suggest that the water situation will transition from abundance to scarcity in the near future. Therefore, and given that most studies have focused on the operational policies of dams and hydraulic structures, there has been a growing need to study and analyse the impact of upstream dam construction on the operation of Iraqi dams, such as Dokan Dam located on the Lesser Zab River. Dokan Dam is one of the most important dams to study due to its size and direct impact on surrounding areas. The aim is to understand the changes in the performance of these structures and the impact of declining water levels. To achieve this objective, and after collecting sufficient data, the HEC-ResSim program was used to study the impact on the dam's operation over a 30-year period from 1980 to 2010. The results showed that HEC-ResSim was effective in simulating the system's operation and studying daily and monthly discharges, as well as its flexibility
