Tan Chau - 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 Tan Chau .

  December January February March April May
1:4 ARI 9616 m3/s 6067 m3/s 4038 m3/s 2595 m3/s 2078 m3/s 2590 m3/s
1:5 ARI 9402 m3/s 5913 m3/s 3913 m3/s 2500 m3/s 1993 m3/s 2447 m3/s
80% FDC 9048 m3/s 5667 m3/s 3718 m3/s 2382 m3/s 1916 m3/s 2217 m3/s
90% FDC 8175 m3/s 5154 m3/s 3277 m3/s 2130 m3/s 1713 m3/s 2014 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.
