A named list with datasets containing the inflow, total diversions, and proportion diverted for the North and South Deltas from three different Calsim runs. Each dataset is stored as an element named by the Calsim run it came from:

  • biop_2008_2009: output from the 2008-2009 Calsim II BiOp run.

  • biop_itp_2018_2019: output from the 2018-2019 Calsim II BiOp run.

  • calsim_run_of_river: output from the Calsim Run of River run.

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.
