Chiang Saen - 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 Chiang Saen .

  December January February March April May
1:4 ARI 1432 m3/s 1074 m3/s 859 m3/s 754 m3/s 767 m3/s 1111 m3/s
1:5 ARI 1398 m3/s 1051 m3/s 837 m3/s 731 m3/s 735 m3/s 1057 m3/s
80% FDC 1379 m3/s 1031 m3/s 834 m3/s 733 m3/s 752 m3/s 1026 m3/s
90% FDC 1281 m3/s 985 m3/s 796 m3/s 679 m3/s 669 m3/s 906 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.
