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.  Video shorts and other bonus content are available at the podcast website:https://www.hec.usace.army.mil/confluence/rasdocs/rastraining/latest/rsm-river-mechanics-podcastand the HEC Sediment YouTube channel:https://www.youtube.com/user/stanfordgibson
