  • "Ask an Editor" with Amy East (Bonus short)
    Jan 11 2025

    The peer review process can feel like hazing to a new (or not-so-new) river scientist. Many excellent practitioners are learning from their rivers every day, but it can feel like if it doesn't get into peer review, it doesn't "count."

    So we separated this short segment from my conversation with Dr. Amy East, the Editor-in-Chief of AGU's Journal of Geophysical Research: Earth Surface (and >10 years experience editing high impact journals) to provide a little primmer on how to negotiate the peer review process. Amy has some really helpful thoughts on how to move from a "Report on a River" to a "Scientific Contribution" that will land well in a journal.

    ...and look for the first episode of Season 4 in a few weeks.

  • Peter Wilcock on Gravel Bed Rivers, Partial Transport, Armor Layer Persistence and Channel Design (Plus Wilcock & Crowe)
    Jun 4 2024

    When HEC hired me to add sediment transport to HEC-RAS almost 20 years ago now, I inherited a set of sediment transport functions that were mostly developed in the early to mid 20th century.
    These were – and continue to be – important equations.
    But when I sat down with the RAS team
    To talk about the new science I was excited to include in a river mechanics model.
    I pulled out the same binder I brought to this interview

    We are wrapping up our third season of the podcast, and our three-part mini series on gravel bed rivers And talking to the scientist who wrote all the papers in that binder, seems like a fitting way to wrap up both.

    Dr. Peter Wilcock spent much of his career at Johns’ Hopkins, where he and his team developed the Wilcock and Crowe transport equation and did some of the most important gravel bed transport work that was hitting the journals when I was coming of age in the field.

    Peter is unquestionably one of the most important contemporary contributors to quantitative gravel-bed transport science and engineering.
    He won the American Society of Civil Engineers Hans Albert Einstein award in 2008 and is a fellow of the American Geophysical Union.

    And we talked a lot about that fundamental, early work, that is just kind of part of established gravel bed transport theory these days.

    But 10 years ago he moved to Utah State, improving his proximity to classic gravel bed rivers, and in the years since I put that binder together of his paradigm shifting work,
    Peter has been very intentional about translating his science into practical channel design methods, particularly for restoration channel designs.

    So we talked about both…starting out with more of the channel design topics and then moving into his classic findings.

    The Link to Peter's Stream Assessment and Design Class Materials (including iSURF) that we talk about is here:

    We also talk about Ron Copeland's channel design method. We made a short video with Ron on that method which is good background for this episode here:

    Finally, we also have an interview with Joanna Curran (the Crowe in Wilcock and Crowe) which makes a good companion to this episode here:

  • Mary Power on River Ecology, Disturbance, and Inverted Pyramids
    Apr 19 2024

    t

    Dr. Power is a food web ecologist at UC Berkeley, where she leads the Power lab which has compiled careful, long term data sets in the Angelo Reserve in Northern CA.

    In addition to her early work, in Panama and the Ozarks - which we touch on briefly - Dr. Power’s multi-decadal data sets on the Eel River, have yielded remarkable findings about how food webs function in gravel bed rivers…and spoiler alert, it sometimes involves the sorts of things we tend to talk about here…like the gravel - and how it transports.

    While this is a physical science podcast, I hoped to include interviews with river Ecologists from the beginning particularly ecologists who make careful observations
    at that interface of physical and biological processes. And I always hoped I could kick that emphasis off with Dr. Power.

    I teach an Ecogeomorphology module in one of our classes here at HEC and I always lead that with the Eel river story she shares About 20 minutes into this episode.
    That Eel river story was one of the early influences that got me interested in the ecological interactions with river mechanics processes.

    I also asked Mary about a couple of Ecological models and categories, that have corollaries in geomorphology. So we talked about disturbance, alternative stable states as well as the Box model and the Ideal Free Distribution, which are just really helpful ideas for anyone who is interested in rivers.

    Dr. Power was inducted into the National Academy of Sciences in 2012.
