Details

The inflow, diversions, and proportions diverted in the North and South Deltas are represented using 'FLOW-CHANNEL' and 'FLOW-DELIVERY' nodes from CALSIM II. The North Delta is defined as the area west of and including the Sacramento River below Freeport to Chips Island. The South Delta is defined as the area east of the Sacramento River below Freeport to Chips Island and the San Joaquin River below Vernalis. The nodes and calculation for each delta are outlined above.
