Abstract: As an important part of hydrological work, the accuracy and quality of hydrological data will directly affect the decision-making of water resources development and utilization as well as engineering design. The accuracy and reliability of the water level and flow data of three hydrological stations, Myitkyina, Jiesha and Debeijin on the main Irrawaddy River were analyzed and compared by analyzing the data sources and their upper-lower relations. The water level and flow rate at Myitkyina Station were verified via survey. The results showed that the water level data at these three hydrological stations are basically reliable. However, the uncertainty and accuracy of the flow data are extremely uncertain. This research provides a favorable reference for the planning and design of water projects in the Irrawaddy River Basin.
