Automated Unimpaired Hydrologic Metric Scaling for California Streams

The objective of this research project is to create an ArcPy-based scripting tool that will generate an unimpaired daily hydrograph for any stream reach in California. The tool will be based on Dr. Belize Lane’s research on classifying natural hydrologic regimes for California, Lane et al. 2017. When completed, this tool will allow the user to predict a suite of unimpaired hydrologic indices for any stream reach in the state regardless of current hydrologic conditions. The resulting estimates can be used to improve stream ecology, flood management, irrigation scheduling, water supply, and other water quality and watershed management decisions.
