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.
