I recently described Chris Nygaard as the Corps’ BSPS, our 'Big Sediment Pulse Specialist.'  He led sediment analysis and modeling on the Corps’ latest evaluation of Mount Saint Helens downstream-sediment impacts and a dam removal alternative on the Snake River.  In those projects he analyzed the fate of sediment pulses (real or hypothetical) on the order of hundreds-of-millions of tons.  But Chris also recently spent a couple years as a project engineer with Bonneville Power’s, where he got to see more small, medium, and large scale, river restoration projects in a couple years than most people see in a career.

We plan to occasionally push out short bonus episodes between our longform conversations.  This first bonus short is a conversation with two of the organizers of the Federal Interagency Sediment Conference, which will be in St Louis in May.  SEDHYD is a conference that specializes in applied river mechanics and engineering topics, and has a lot of overlap with the topics of the conversations we're having on this feed.   So I invited two of the conference leaders to talk about it.

Dr. Tim Randle (Bureau of Reclamation) and Dr. Paul Boyd (Corps of Engineers) are part of the team of agency sediment specialists planning this conference.  

SEDHYD is in St Louis May 8-12, 2023.  You can find out more at: https://www.sedhyd.org/

 John Remus leads a team of Corps of Engineers, sediment and river engineering, subject-matter experts.  This team (which I like to call "the Sediment Avengers") deploys to the Corps' most problematic sediment and morphological challenges around the country.  And that's a fitting role for the man who manages the river sometimes called the "Big Muddy."  In his "day job," John is currently the the chief of the Corps Missouri River Basin Water Management Division where he leads the team that manages the massive reservoirs on the upper Missouri.

But for most of his career John led the Sedimentation and Reservoirs branch at the Corps' Omaha district.  Over the years I made two observations about this branch: 1) it was the only Corps-District Branch with an specific sedimentation mission and 2) it generated a remarkable amount of sediment analysis and river mechanics talent...which always made a lot of sense to me, given how much I've learned from John Remus over the years.

Dr. Joanna Curran is probably best know for her early, academic, laboratory work on step-pool systems, gravel cluster turbulence,  and the Wilcock and Crowe transport function.  But she has since worked on northwestern rivers with several engineering firms, and most recently joined the Corps of Engineers at the Seattle District.  This academic/private sector/public sector perspective and experimental/numerical/field experience gives her a couple different multi-perspective views on rivers.  When you match those perspectives with a fundamental curiosity about how sediment processes work, it makes for a fascinating conversation.  

We talked about Wilcock-Crowe, step pool systems (see her flume experiment video at the webpage), gravel clusters, "low flow bed tempering," the impact of vegetation "porosity" on sediment mechanics, and several other topics.

Ron Copeland has worked for the Corps of Engineers for over 5 decades, 52 years at the Los Angeles district and the Corps' Coastal and Hydraulics lab in Vicksburg Mississippi. He also worked for 10 years as a principle engineer at Mobile Boundary Hydraulics, which was the premiere 1D sediment transport modeling firm for decades.  But Dr. Copeland has not only been on a very short list of the very best 1D sediment transport modelers for decades, he also developed several equations and algorithms that multiple models use.  In 2020, he won the ASCE, Hans Albert Einstein award. 

And, while I think Dr. Copeland's modeling expertise has a lot of value to the community growing around this podcast (and we spent some time talking modeling) his sediment and river mechanics contributions include much more .  He led a team who wrote the Corps early guidance on restoration channel design and developed an important, expedited, tool to evaluate sediment continuity of restored channels, a common failure mode of early restoration projects.  We talked to him about all of that...and some more technical topics that we spun out into video shorts (see the website link).

Molly Wood is the National Sediment Specialist for the USGS Water Resources Mission Area’s Observing Systems Division. She develops policies and methods for measuring fluvial sediment transport and for computing streamflow using complex rating techniques. She also teaches national and international training courses on surface-water and sediment data collection.

I have lost track of just how much of what I understand about sediment data I've learned from Molly.  But a substantial percentage of what I know about sediment measurements, sediment data processing, and potential data pitfalls comes either from her publications or conversations we've had over the years.   This was a fun conversation that hit on several of those topics.

We talked about the sediment data types that the USGS collects and publishes, concentration-vs-load, sources of flow-load variability, isokinetic sampling, common sediment data interpretation errors, sediment surrogates, international sediment sampling studies, the future of sediment sampling, and several other topics.

You can find the data we talked about at the USGS NWIS Water Quality and Sediment Data Site: https://waterdata.usgs.gov/nwis/qw

Dr. David Biedenharn is a river mechanics, subject matter expert, with the Corps of Engineer's Coastal and Hydraulic Laboratory.  He is a professional engineer with over forty years of experience in hydraulics, river engineering, sedimentation, channel restoration, and fluvial geomorphology.  Dr. Biedenharn also teaches in the Tulane Department of Science and Engineering, where he helped develop their River Science and Engineering Program. 

But the main reason we invited David to be the first guest on the podcast, is that he is responsible for mentoring a generation (and, by now, more than one generation) of River Scientists and Engineers in the Corps of Engineers.    From the first time I met him in my early 20's, conversations with David have formed the way I think about river processes and our engineering interventions in river systems at every scale.  

We talked about his experiences mentoring new river scientists and engineers, the lessons the Corps learned from the "demonstration project," the appropriate place of rock and vegetation in restoration design, and balancing the "E's" of human intervention in river systems.
