Pakse - Article 6A for planning purposes (pending issue)

The acceptable flows framework for planning purposes during the dry season is based on the monthly average discharge in the dry season (December-May) during 1986-2000, as simulated by the Baseline scenario in the DSF at Pakse .

  December January February March April May
1:4 ARI 3539 m3/s 2387 m3/s 1719 m3/s 1378 m3/s 1467 m3/s 2187 m3/s
1:5 ARI 3442 m3/s 2341 m3/s 1677 m3/s 1335 m3/s 1418 m3/s 2056 m3/s
80% FDC 3133 m3/s 2292 m3/s 1611 m3/s 1319 m3/s 1371 m3/s 1829 m3/s
90% FDC 2888 m3/s 2148 m3/s 1502 m3/s 1224 m3/s 1272 m3/s 1654 m3/s
Flow framework cConsiderations

For each month, a range of thresholds is used to consider the year-to-year natural variation of water availability. In case of a wet year, the monthly minimum flow will be maintained at the upper bound while the lower bound will be applied in case of a dry year. In average, the monthly minimum flow should be maintained between the threshold ranges.

A considered scenario could NOT be deemed acceptable for planning purposes if the average discharge simulated by the DSF is below lower bound for one or more months of the dry season at one or more of the selected hydrological stations.
