Evaluation of Tigris River discharges at Baiji station comparison with discharges of the upstream and downstream stations / Iraq

Abstract

Measuring the discharges of Tigris River in Baiji is very important because it gives the final result of the flows coming from the Mosul Dam and the upper and lower Zab River, which are sent downstream towards the control system in Samarra.

In this paper, the records of levels measured manually using the scale inserted in the station were reviewed, which are translated into discharges according to the discharge-level equation deduced from the traditional measurement data, or the measured discharges using the Acoustic Doppler Current Profiler (ADCP), and a significant discrepancy was found between the measured discharges by the two methods, There is a great exaggeration in the discharges measured in the first method, compared to those measured in the second method, or in comparison with the total discharges coming from Al-Shirqat stations on Tigris and Al-Debs on the Lower Zab River, above the Baiji station, or those discharges sent to Al-Alam and Tikrit stations below the Baiji station
