Phnom Penh - 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 Chrouy Changvar .

  December January February March April May
1:4 ARI 6112 m3/s 3564 m3/s 2497 m3/s 1952 m3/s 1891 m3/s 2679 m3/s
1:5 ARI 5952 m3/s 3476 m3/s 2427 m3/s 1897 m3/s 1823 m3/s 2498 m3/s
80% FDC 5445 m3/s 3329 m3/s 2342 m3/s 1945 m3/s 1775 m3/s 2190 m3/s
90% FDC 4806 m3/s 3076 m3/s 2058 m3/s 1729 m3/s 1629 m3/s 1957 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.
