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 (add link).
