  • Title

    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.

    Soil type as a driver of agricultural climate change response in the Sacramento-San Joaquin Delta

    Lead University of California - Berkeley [UC Berkeley]
    Description This research project aims to increase understanding of how iron-rich peatland soils cycle carbon, nitrogen, and phosphorus in the delta and establish how carbon and nitrogen biogeochemistry and greenhouse gas emissions vary with management practices and crop type. It also explores how a drier future climate will influence biogeochemistry and greenhouse gas emissions in iron-rich soils and how to best adapt land management practices. The goal of this research is to identify agricultural practices that can generate a portfolio of climate change adaptation and greenhouse gas mitigation strategies for delta farmers. The greenhouse gas data collected as part of this research also helped to generate increasingly accurate emission offset credits for potential wetland restoration projects in California’s Cap-and-Trade program.

    Next Generation Multi-Hazard Levee Risk Assessment

    Lead University of California - Los Angeles [UCLA]
    Description In June 2004, a 350-foot levee section gave way west of Stockton, flooding crops and more than a dozen homes, and challenging state officials to protect the state's water supply. What is the risk of that happening again somewhere in the Delta? In light of agricultural fields sinking, the sea level rising, more frequent and severe floods occurring, and earthquakes looming, improvements are estimated to cost $3.8 - $4.3 billion over the next few decades. This study combines 3-D representations with information on the levee’s structure to analyze how different levees respond to floods, sea level rise, and earthquakes. State officials released the last Delta Risk Management Strategy a decade ago. Since then, scientists have collected significant amounts of data and have developed new procedures to compute the risk of failure. This work will produce new Delta-wide data sets important for characterizing the hazards coming from floods and earthquakes. It will also develop the best method to conduct levee hazard assessments. Applying this new method will ensure wise investments and effective threat mitigation Delta-wide.
