    Delta Wetland Resilience and Blue Carbon

    Lead San Francisco Estuary Institute [SFEI]
    Description This project estimates carbon storage for the past, present and future Delta, as well as GHG fluxes and elevation change based on chosen restoration and rice farming scenarios in the future Delta using the Delta Landscape Scenario Planning Tool. The project also investigates how well the current organic matter parameterizations and inorganic sediment parameterization in the Marsh Equilibrium Model (MEM) represent Delta marsh accretion processes. Knowledge of marsh accretion and migration will be used to develop a spatial conceptual model of marsh resilience in the Delta.

    Improving subsidence and carbon emissions modeling

    Lead Hydrofocus Inc.
    Description

    On-going subsidence of organic soils threatens the physical structure of the Delta, its central role in the state’s water system, many diverse species that depend on it, and threatens future agricultural production. Knowledge of baseline
    emissions and subsidence rates is important for developing alternative land use scenarios for maximizing benefits for sequestering carbon, reducing or reversing subsidence, providing income for landowners via the carbon market, and
    reducing flood risk. 
    This project will gather, process, and analyze recent data in the Delta for land-surface elevation changes, greenhouse gas fluxes measured by eddy covariance and gas chambers, soil organic matter content, depth-to-groundwater, and soil
    organic thickness. These data will be used to update and calibrate the SUBCALC model and refine model inputs to improve the model’s ability to simulate subsidence and CO2 emissions. Collaboration with the Jet Propulsion
    Laboratory and UC Berkeley will allow use of CO2 flux and InSAR data to calibrate and validate the SUBCALC model. The Delta Conservancy is another partner assisting with assessment of modeling for land-use conversion planning.
    TNC and Metropolitan Water District are partners to assist with use of SUBCALC for engagement of the carbon market and collaborate with the Suisun RCD to improve estimates of subsidence and CO2 emissions.
