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...

tDr. 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 - whic...

Dr Alain Recking has quantified gravel bed transport with just about all the tools available to our discipline.In addition to substantial field work- Dr. Recking has done some important and influential flume experiments.We have ...

A couple years ago, my agency asked me to write some guidance on sediment modeling, so, I reached out to the morphological modelers I knew, and particularly the model developers who write the morphological model code other people use.I ...

I’ve heard people call Tony the godfather of Sediment Transport Modeling and - as you’ll hear in our conversation - he very well may be the first person to use a computer to answer an engineering scale sediment question.But most people ...

Dr. Jim Selegean is the Sediment Transport Specialist at the Corps Detroit District where he studies the rivers and sediment loads into the great lakes as well as inland costal processes. He is also a professor at Wayne State in Det...

Dr. Astrid Blom is a professor Civil Engineering & Geosciences at Delft University of Technology in the Netherlands is perhaps best known for her recent reach and rive scale work, modeling hundreds of kilometers, sometimes for hundreds or t...

In the previous episode, we talked to Dr. Marcelo Garcia about the astonishing compilation of sediment science he edited, the ASCE Sedimentation Manual.   In this episode, we turn to some of his work, covering a wide range of ...

Dr. Marcelo Garcia holds an endowed chair in Hydraulics at the University of Illinois-Urbana – where he has taught for more than thirty years, and runs the remarkable Ven Te Chow hydraulic and sediment laboratory. His award page re...

Dr. David Montgomery has been so prolific, that for several years I actually thought he was two people:First, Dr. D. Montgomery is a well known geomorphologist from the University of Washington (and a 2008

We plan to start releasing season three on the first week of the new year.  It was a fun and helpful season, which I'm looking forward to releasing.This preview overviews the guests and topics of the season with fun pull qu...

Jennifer Bountry leads the Sedimentation and River Hydraulics Branch of the US Bureau of Reclamation's Technical Service Center in Denver, CO where she helped to coordinate and draft an

In the first two episodes of this season Dr. Annandale and Dr. Morris talked about reservoir sediment management practices all over the world.  But examples in the continental US were noticeably absent.   Reservoir sediment management...

Dr. Greg Morris wrote the first text on reservoir sediment management, which generated the categories and set the parameters for a lot of the work and conversations surrounding the topic in the last three decades.  Most of us who work in t...

Dr. George Annandale has been advocating for forward thinking about global water supply for decades...which is more connected to sedimentation processes than you might imagine.  In his book, Quenching the T...

The RSM River Mechanics Podcast is returning with a summer mini-season on reservoir sediment management.  We recorded four episodes on this topic with some remarkable guests, so we're running them together this summer as a shorter "Season ...

We are wrapping up season 1 with the second half of our first interview.  This is the rest of my conversation with US Army Corps of Engineers River Mechanics and River Engineering Subject-Matter Expert, Dr. David Biedenharn.If you ...

 The regressive erosion on the Rio Coca (Ecuador) may be the morphological event of our generation.  But, because it happened in February 2020, when there was not much room in the news cycle, most people haven't heard about it...even ...

Dr. Richard Iverson led the mud and debris flow investigations at the USGS Cascade Volcano Observatory for years, including large scale flume and numerical work that unlocked a remarkable number of new insights about these high-concentration fl...

Dr. Katie Brutsche led the Regional Sediment Management Program for several years.  Regional Sediment Management is the "RSM" in the title of this podcast, and the reason this project exists.  RSM is the aspirational conceptual model ...

 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 al...

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...

 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 challe...

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 sev...

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 Bounda...
