Dr. Kris Taniguchi-Quan is a hydrologist/geomorphologist who specializes in assessing and managing the hydrology of streams.  Her research focuses on developing a variety of tools and models to understand how future changes in climate, land use, and management practices may impact the hydrology and physical habitat of rivers and to establish ecohydrology targets designed to protect stream health.  She serves on the California Environmental Flows Framework (CEFF) technical team and is implementing CEFF through a variety of California applications focused on stormwater capture, wastewater reuse, dry-season diversions, and cannabis cultivation.

She received her B.S. in environmental science - watershed science in 2011, her M.S. in geography in 2014 from San Diego State University (SDSU) and her Ph.D. in geography from the joint doctoral program at SDSU and University of California, Santa Barbara in 2018. She joined SCCWRP in 2018.
