Khong Chiam - 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 Khong Chiam .

  December January February March April May
1:4 ARI 3297 m3/s 2253 m3/s 1599 m3/s 1287 m3/s 1372 m3/s 2151 m3/s
1:5 ARI 3222 m3/s 2210 m3/s 1562 m3/s 1246 m3/s 1325 m3/s 2022 m3/s
80% FDC 3001 m3/s 2121 m3/s 1503 m3/s 1244 m3/s 1271 m3/s 1758 m3/s
90% FDC 2789 m3/s 1968 m3/s 1403 m3/s 1142 m3/s 1171 m3/s 1586 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.
