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 2025-05-22 release. Version 2025-05-22 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).
