Historical Simulation Checklist

Verifying an Extension of the Historical Simulation

Bob Suits 10/16/2020

Verify Input Hydrology

Check Boundary Conditions

  • Sacramento River inflow
  • San Joaquin River Inflow
  • Sacramento River + Yolo Bypass Inflow
  • Banks pumping
  • Jones pumping

Get Observed Data

Preferably get the Sacramento and San Joaquin River inflows and Banks and Jones pumping from DAYFLOW. If DAYFLOW isn’t complete, get remainder daily average flow from CDEC. It needs to be independent of the DSM2 set-up.

Get reported flow at SRV (Rio Vista) and generate daily average flow.

Generate daily average flow from DSM2 simulation at:

VCU, ORI, OH4, OBD, GLC, RSAC101, RSAN115, RSAC155

Compare daily average observed flows to DSM2-simulated flows at boundaries

Verify timing of installation and removal of temporary barriers and operation of Montezuma Control Structure and Delta Cross Channel Gates

  1. Create a dss file with the observed and simulated 15-minute data. Compare observed and simulated stages just upstream and downstream of each barrier site. This would already have been done with observed data in establishing the timings by looking at observed stages. Now repeat the analysis in order to confirm that you got the operation timing correct.
    Barrier Stations to use to check
     Middle River ​MUP and (MAB or MTB)
    Grant Line Canal GCT and GLE
    Old River OBD and (OAD or ODM)
    Old River at Head OH1 and SJL

  2. Compare internal daily average flows affected by gate operations
    Observed Simulated
    DLC DLC Delta Cross Channel
    NSL SLMZU025 Montezuma Slough at National Steel

  3. Check key internal flows for overall circulation of Delta waters

Verifying EC

Get OCO’s monthly updated EC estimates at: Banks, Jones, OH4, OBI to compare to
Delta Modeling Section’s historical simulation and reported EC.
