  • Research shows state’s strategy for river cleanup may be all washed up

    SDSU News Center April 2025

    Results from our NOAA-funded project on trash sources and transport in the San Diego River was featured by the SDSU News Center on the effectiveness of proposed ‘trash capture’ solutions to reduce plastic and debris in California’s urban rivers. The article cites our finding that storm drains are not the main source of trash, and so installing capture devices will have limited impact.

    “full capture systems don’t stop trash from being dumped into the river next to homeless encampments, which are thought to be the source of 62 to 75% of the debris, according to the research findings”

    The article therefore highlights the importance of volunteer clean-ups to remove trash from the river corridor and prevent emission to the ocean.

  • In SDSU’s Own Backyard

    SDSU Magazine Spring 2025

    Results from our NOAA-funded project on trash sources and transport in the San Diego River was featured in the SDSU Magazine as part of an article on university researchers contributing scientific solutions to issues of importance to San Diego County. The article cites our finding that storm drains are not the main source of trash; instead, “anywhere from 79 to 92% of the trash—plastic bags, clothes, mattresses—can be traced to the floodplains along the river and direct dumping, often adjacent to homeless encampments”. The article therefore highlights the importance of volunteer clean-ups to remove trash from the river corridor and prevent emission to the ocean.

  • Measuring streamflow using video

    SDSU video

    This short video shows photos of students in my research group taking streamflow videos and flow measurements with a current meter. Our aim is to test ‘Particle Image Velocimetry’ (PIV) as a technique for measuring flow in small, ephemeral streams in San Diego. We are testing different options (type of camera, camera angle, cross section measurement technique, etc) to determine which is most important in estimating accurate flow. Our long term goals are to advance flow mapping in urban areas and to understand what landscape factors control flood flows in urban canyons.

  • Fingerprinting our water

    SDSU 2017-18 Research Highlights

    My research with Masters student Sierra Wallace was featured by the SDSU Research Foundation for their 2017 – 18 Research Highlights. The article (below) describes our work on using stable isotopes as “fingerprints” of water, to track the interactions of surface-water and groundwater in San Diego’s Mission Valley aquifer. Our research is supported by the City of San Diego and will support their long-term planning for water supply and sustainability in San Diego.

  • Scared of the Rain

    Popular Science Article

    The popular science magazine “Water and Atmospheric”, published by the National Institute for Water and Atmospheric Research, interviewed me and featured my research on flood forecasting for their story “Scared of the Rain: Understanding and predicting floods and their impacts”.

    The story featured the record-breaking flooding in New Zealand in early winter 2015, and asked Why did the floods occur? Should we expect more? Can we predict future floods?
