DSM2 Input 2025-05-28 historical update

The following is a summary of the features from the DSM2 Monitoring Special Study (MSS) release that were merged into the
DSM2 2023 Full Calibration Release (FC_2023.01)* to create the "DSM2 Input 2025-05-28 historical update" release.
The "DSM2 Input 2025-05-28 historical update" release was calibrated using DSM2 v8.4.1.

  • Delta Modeling Section (DMS) standard directory structure and file naming conventions
  • MSS time period, calendar years 2015-2024
  • Time series input from MSS, with Yolo Bypass and Yolo Toe Drain inputs added.
  • Five minute time step for boundary flow and EC inputs
  • Martinez stage boundary input adjusted to compensate for the lack of simulation of wind and density-induced pressure gradient from salinity gradients
  • Channel depletions adjusted to improve simulation of null zone diversions and improve circulation patterns around Fabian Tract and Pescadero Tract.
  • Inferred drainage EC inputs from MSS for South Delta. All negative values were replaced with zeros.
  • Gate configuration and operating rules from MSS, with one change to the operating rules to correct an error in the operation of the Suisun Marsh Salinity Control Gates (SMSCG)
  • Input allows for variable delta x in different parts of the domain.
  • Cross-sections updated in South Delta using DEM for Modeling, Version 4.3 (https://data.cnra.ca.gov/dataset/san-francisco-bay-and-sacramento-san-joaquin-delta-dem-for-modeling-version-4-3).
