  40. TREAM FLOW MEASUREMENT • Determination of available head (H) under different flow conditions (Q) at a dam sites for Hydropower Generation. • For obtaining a more accurate flood hydrograph for short intervals during a flood period, as discharge measurement at short interval is impossible during high flood. • During floods, sometimes practical difficulties may prevent the observation of discharge, in such situations discharge can be obtained from the stage-discharge relationship. • Extrapolation of stage-discharge relationship to determine the peek discharge (Q) for designing of any hydraulic structure. 40
