Project: Quantifying Biogeochemical Processes through Transport Modeling: Pilot Application in the Cache Slough Complex

Description: Funding for this project will focus on observations and hydrodynamic models of the Cache Slough Complex. To accomplish this, the project implementation will involve making extensive use of models developed in ongoing CDFW-funded projects. These projects have included the development and initial calibration of a two-dimensional hydrodynamic model of the Cache Slough Complex. The model utilizes the Deltares Flexible Mesh numerical model, an open-source hydrodynamic model applied in a growing number of studies in the Bay/Delta system. Work is continuing in that project to refine the model calibration within the Cache Slough Complex and extend the calibrated period. The model is also being applied to study how tidal forcing and channel configuration shape the hydrodynamic connections between parts of the system.

Reference Number: 3600BQ1996064

Implemented By: Regents of the University of California, Davis

Objective: This project is part of a larger goal to develop a modeling and analysis framework for quantifying biogeochemical condition and rates within the system. This project will serve as a pilot for the application of this framework in other parts of the Delta or across the Delta as a whole, with capabilities to: (1) Leverage historical discrete and station-based data to map biogeochemical constituents across broad areas in near real time, (2) Link water quality and habitat conditions across the study area to flow and landscape elements such as wetlands, shallow water areas and channels, and (3) Provide biogeochemical process and rate information for mechanistic biogeochemical modeling, essential for predicting effects of future management actions, restorations and climate change.
