The discharges can be calculated as follows:Average discharge (Q avg.) = 200,000 × 300 LPCD = 60,000,000 L/day = 60,000 m3/day =0.694 m3/s.Minimum discharge (Q min) = 60,000 × 0.4 = 24,000 m3/day = 0.278 m3/s.Maximum discharge (Q max) = 60,000 × 1.8 = 108,000 m3/day = 1.25 m3/s.Fig. Greater-Zab River on the map.
