CALIFORNIA ENVIRONMENTAL FLOWS FRAMEWORK (CEFF) DECISION SUPPORT TOOLS I

The California Environmental Flows Framework (CEFF) requires a set of decision support tools to support statewide implementation. We describe emerging open-source technical tools to visualize and quantify functional flow components in California, including: (1) a statewide stream classification and water year typology, (2) dimensionless reference hydrographs, and (3) the functional flows calculator. The functional flows calculator is a hydrologic feature detection algorithm that extracts high-resolution flow metrics from any stream gauge using signal processing techniques. It improves on previous flow metric calculation suites (e.g. IHA, EflowStats) in that it is founded on ecological theory, hydrologically driven, and robust to immense hydrologic variability, supporting flow assessment in large heterogeneous regions like California. This suite of open-source visualization and assessment tools allows users to explore and interact with California’s natural hydrology and assess current alterations or proposed flow management scenarios. These decision support tools are publicly available at https://eflows.ucdavis.edu.
