Stung Treng - 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 Stung Treng .

  December January February March April May
1:4 ARI 5592 m3/s 3362 m3/s 2363 m3/s 1908 m3/s 1866 m3/s 2713 m3/s
1:5 ARI 5453 m3/s 3287 m3/s 2300 m3/s 1856 m3/s 1799 m3/s 2526 m3/s
80% FDC 4990 m3/s 3185 m3/s 2209 m3/s 1912 m3/s 1778 m3/s 2206 m3/s
90% FDC 4439 m3/s 2932 m3/s 2012 m3/s 1653 m3/s 1614 m3/s 1923 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.
