Chau Doc - 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 Chau Doc .

  December January February March April May
1:4 ARI 1435 m3/s 566 m3/s 257 m3/s 148 m3/s 115 m3/s 188 m3/s
1:5 ARI 1369 m3/s 539 m3/s 242 m3/s 139 m3/s 107 m3/s 172 m3/s
80% FDC 1184 m3/s 484 m3/s 207 m3/s 140 m3/s 109 m3/s 160 m3/s
90% FDC 976 m3/s 404 m3/s 163 m3/s 107 m3/s 81 m3/s 135 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.
