Delta Flows and Diversions — delta

A named list with datasets containing the inflow, total diversions, and proportion diverted for the North and South Deltas from two different Calsim II BiOp runs. Each dataset is stored as an element named by the Calsim II BiOp 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.

Format

a named list where each element contains a dataframe with 972 rows and 7 variables:

date: CALSIM II date
n_dlt_inflow_cfs: C400 + C157, north delta inflow in cubic feet per second
s_dlt_inflow_cfs: C401B + C504 + C508 + C644, south delta inflow in cubic feet per second
n_dlt_div_cfs: D403A + D403B + D403C + D403D + D404, north delta diversions in cubic feet per second
s_dlt_div_cfs: D418 + D419 + D412 + D410 + D413 + D409B + D416 + D408_OR + D408_VC, south delta diversions in cubic feet per second
n_dlt_prop_div: north delta diversions / north delta inflow
s_dlt_prop_div: south delta diversions / south delta inflow

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.
