Turning seawater into sweet water, S12E1

The Klamath River is transforming after four dams were removed in 2024. In this episode, we join the research team studying the impacts of the dam removals on plant and algae. Hear from the students and faculty about what they are learning at the confluence of engineering and ecology.   BONUS CONTENT  River Rebalance (story)  Mark Bransom Heads the Historic Klamath Dam Removals (video)  How Engineers Decommissioned Four Dams Along the Klamath River (lecture video)  Rewilding the Klamath (story)  What it Takes to Take Down a Dam (podcast) 

The removal of four dams from the Klamath River was a once-in-a-lifetime opportunity to capture the interplay of science, engineering, and culture. Desirée Tullos, professor of water resources engineering at Oregon State University assembled a collaborative team that unites Western science and traditional ecological knowledge of Indigenous people.   BONUS CONTENT:  What it Takes to Take Down a Dam (podcast) Unrestricted Flow (video about River Engineering field trip on the Klamath)   

This is a historic year on the Klamath River, where the biggest dam removal in the U.S. is underway. The hope for the monumental engineering project is that it will restore some balance to a damaged ecological system. We hear from Mark Bransom, who is overseeing the demolition and restoration, about why and how it’s happening and some of the challenges of the project.

Will swarms of unmanned aerial vehicles be able to aid humans in wildland firefighting or package delivery? Research summarized in a new paper in Field Robotics represents a big step towards realizing such a future. In this interview, Professor Julie A. Adams describes the research showing that one person can supervise more than 100 autonomous ground and aerial robots. 

The final episode of the season occupies a time of transition, as spinoff company Espiku ramps up. We get an update on two systems that received patents and a third that could provide an environmentally benign technology for extracting lithium. We also hear from four graduating students who reflect on their experiences.

The pandemic didn’t stop Bahman Abbasi’s desalination research. In this third episode, we learn about the successful lab-scale demonstration of his team’s technology and the next steps toward its commercialization. Plus, the team takes on a new project to clean up wastewater from oil and gas production. Bonus content:  Espiku, OSU spin-off company  Turning freshwater into saltwater, Bend Source article 

In the second episode of this four-part season, we travel to Bend, Oregon to visit the Water and Energy Technologies Laboratory and meet the team that is inventing a new technology to desalinate water. Bahman Abbassi, associate professor of mechanical engineering, talks about building the lab from the ground up, and graduate student Mohammed Elhashimi demonstrates their system to desalinate water.  Bonus content:  Quest for Clean Water (story, video)  Water and Energy Technologies Laboratory 

Can turning seawater into drinking water be a cost-effective way to provide clean, fresh water for the growing numbers of people facing water scarcity? Bahman Abbasi, associate professor of mechanical engineering, is taking up that challenge with a mobile, modular, solar-powered, desalination system. This is the first episode in a four-part season.
