Evaluation of the Performance of a Discharge Gauging Station on Tigris River in Baiji, Iraq

Gauging the discharge of theTigris River in Baiji is very important, as it reflects final accumulated flows from Mosul Dam, upper and lower Zab tributaries, which send downstream to control system Samarra. The current study aimed evaluate performance gauging station for measuring water levels discharge, thus suggest alternative locations. Large disagreement was found between manually measured that by Acoustic Doppler Current Profiler, comparison with coming stations Shirqat Al-Dibs upstream Baiji, or those discharges sent Tikrit station. A topographical survey flow section done determine area using manual Profiler techniques original Then velocity measured, then calculated according area, average different levels, stage-discharge equation deduced compared other equations used previously. concluded inefficient, better move second site, comparing three stations, we most accurate measurements were at
