Stage –Discharge Relationship For The Hydrometrey Station at Mosul

AbstractData of daily stage - discharge for the Tigris river have been collected for the years (1977 2002 ). Suitable analysis was done to find a new relation between stage-discharge which must be followed to find the discharge from the stage. Trend analysis for stage has been done to see how the stage can be changed in future, which shows a decrease with time. From the relation between max discharge, probability, and stage the inundated areas were determined depending on the contour map of Mosul town, the inundation areas have stages between (220.89-221.3) m when the channel of the river reaches its maximum capacity.
